SKYRESTORE
(EXTRA THICK - 2%)
DIGESTIVE SOLVENT FOR FULLY CURED
ONE OR TWO PACK POLYSULPHIDE
SKYRESTORE digests; its more than a solvent. Its chemical action shears the
?br>
polysulphide molecule, breaking it up into short lengths, thus rendering the polysulphide
soluble. SKYRESTORE is effective on both cured and uncured material so it is ideal for
removing unwanted polysulphide.
?SKYRESTORE does not contain aromatic or halogenated solvents; the ingredients are
also biodegradable so SKYRESTORE is 'environmentally friendly', plus a low hazard
when used as directed.
?SKYRESTORE will only digest polysulphide, but will also dissolve partially cured
polyurethane, paints, inks and other polymeric material.
?SKYRESTORE is a low evaporating liquid with a Flash Point of 56C(Open Cup). It is
classified 'Irritant' under EEC supply legislation.
APPLICATION
As SKYRESTORE will digest and dissolve fully cured polysulphide its main advantage and use is to remove fully
cured polysulphide and adhesives; something that ordinary solvents will not do. It can be used to clean
dispensing equipment, remove tank linings, remove polysulphide residue from joints and around window
frames; and reclaim rejects. The potential applications are too numerous to list. SKYRESTORE can be used
anywhere that fully cured (or uncured) polysulphide needs to be removed for cleaning, reclamation or
maintenance purposes.
DILUTION
There is no need to dilute - use neat.
METHOD OF USE
Apply SKYRESTORE liberally to the area to be treated and ensure area is kept moist; leave until the
polysulphide dissolves. The action starts immediately but the length of time required will depend on the thickness
of the polymer. This time may be dramatically reduced if the area can be agitated by brush/spatula. If dispensing
or other equipment has to be cleaned fill with SKYRESTORE and circulate through the system.

Subject Removing cured sealant with Elixair SkyRestore
The SkyRestore material has been cleared for use on the 146/RJ aircraft for the removal of cured sealant.
There is no process specification written to cover this operation at present but the procedure proposed is as
follows: -
1. Swab clean the sealant to be removed with the solvent cleaner in accordance with AVP 2-024.
2. Apply SkyRestore gel to the sealant by brush and allow to dwell for sufficient time to soften the
sealant. (Approx. 20 minutes).
3. Agitate the coated sealant with a non-metallic scraper (eg Tufnell) to aid removal.
4. Clean off the softened sealant with cloths and/paper towels and swab clean with water wetted
cloths.
5. Wet abrade the cleaned areas with medium red Scotchbrite to remove any softened epoxy
primer. Swab clean with water and dry the surfaces.
6. Apply Alocrom 1200 to any exposed metal surfaces in accordance with AVP 2-007.
7. Thoroughly dry the surface and apply a brush coat of epoxy primer to AVP 3-003 to restore the
protection.
8. After four hours drying of the primer coating, fresh sealant can be applied as required, to
AVP 4-002.
9. The manufacturers recommended safety procedures shall be followed when applying
SkyRestore. Any health and safety queries arising from the application should be referred
to Derick Burton at Woodford (ext. 4145}

TASK 3139 - CHEMICAL REMOVAL OF PRC USING ELIXAIR PRODUCTS - ON AIRCRAFT
TRIAL AT RAF ST ATHAN 21 APR 98.
Reference:
A. SMG/513367/4/3139 dated 20 Mar 98.
1. At Reference A, this office was tasked to investigate the use of the Elixair range of
aviation products to facilitate removal of PRC from the centre fuselage bag tank area, and to
conduct an on-aircraft trial at RAF St Athan.
INTRODUCTION
2. REI 1592 (work instruction) details an NDT inspection of the internal structure
associated with the centre fuselage fuel tank skin area. The NDT inspection requires the removal
of PRC from the centre fuselage tank skin structure. RAF St Athan have allocated 300 manhours
for the mechanical removal of the PRC to enable this instruction to be carried out. In an effort to
reduce this timescale, the use of the Elixair product range has been identified as a possible
alternative method of PRC removal. An authorised on-aircraft trial of these products was carried
out at RAF St Athan on 21 Apr 98.
ELIXAIR RANGE OF AVIATION PRODUCTS
3. Elixair products are manufactured by LMC Chemical Ltd, Unit 2, Roman Hill Trading
Estate, Broadmayne, Dorchester, DT2 8LY; their Aviation Consultant is Mr Len McLaughlin, Tel
01305-852999.
4. The range consists of 3 main products that are of particular interest, which are
known under the brand names Sky Wipes, Sky Wash and Sky Restore.
a. Sky Wipes. This product is a solvent-free wipe impregnated with Sky Wash and
lanolin. It is supplied in tubs of 300 wipes, similar to baby wipes, that are kept moist
by a resealable top. Sky Wipes are considered non-hazardous and protective
clothing/equipment is not required. Sky Wipes are primarily used for the removal of
25
wet or tacky polysulphides (including PRC), particularly the residue left after using
Sky Restore. It is also effective in cleaning tooling and can be safely used to remove
sealant contamination from hands. It should be noted that the wipe is a cleaning
product, not a degreaser as the lanolin leaves an invisible residue that requires
removal using Sky Wash. Sky Wipes are also considered to be a safe alternative to
MEK.
b. Sky Wash. Sky Wash is a liquid degreasing agent that can be dispensed
directly from its container by brush or cloth, or more effectively through the use of a
plastic spray bottle. Sky Wash is a neutralising agent for areas where Sky Restore or
Sky Wipes have been used. Although Sky Wash is classified as non-hazardous, and
it does not contain lanolin, wearing of rubber gloves is nevertheless recommended.
c. Sky Restore. Sky Restore is a thixotropic solution used for the removal of
fully cured sealant. Sky Restore is classed as an irritant and suitable protective
clothing must be worn. This should include overalls, rubber gloves and goggles. (For
the Hawk trial and subsequent removal of the PRC in the fuel tank area, forced air
breathing apparatus was used). Sky Restore is applied undiluted by brush directly
onto the PRC and left for 30-45 minutes, dependent on the thickness of the PRC to
be removed. A chemical action occurs between the Sky Restore and sealant,
breaking up its molecular structure and rendering it soluble. The sealant can then be
easily removed using non-metallic scrapers.
INVOLVEMENT OF OTHER AGENCIES
5. During investigation by this office, it became apparent that other agencies within the
RAF had shown considerable interest in this product, particularly SM35e(RAF), the Support
Authority for Non-Metallic Materials and Aircraft Washing Equipment. The Hercules AEDIT are
also carrying out an evaluation of the product, as are 2(Eng) Tornado Sqn, RAF St Athan. This
office was further informed by SM35e that DERA, Farnborough and DESAT (Dangerous
Engineering Substance Advisory Team), RAF Halton were evaluating the product for its effect on
aircraft structure, and health and safety aspects. In addition we have recently been made aware
by LMC Chemical Ltd that the Institute of Naval Medicine (IONM), the Naval equivalent of DESAT,
has approved the productive. This office has been able to confirm that Mr Andy Britton of IONM
((01705)768168) has approved the product providing the manufacturers instructions are adhered
to. Supportive evidence from Elixair also indicates that their product range has also been
successfully tested by Aerostructures Hamble on Airbus products and by Boeing.
ON AIRCRAFT TRIAL AT RAF ST ATHAN
6. An on-aircraft trial took place at 6 Sqn, RAF St Athan on 21 Apr 98, with the following
in attendance:
Mr P A Oldershaw SMG RAF Wyton (SM35e(RAF))
Mr N Jones SMG RAF Wyton (SM35e1(RAF))
FS G D Browne Hawk AEDIT, RAF Valley
Chf Tech G Hallsworth SMG RAF Wyton (SM57als(RAF))
Sgt S Walsh 3 Sqn, RAF St Athan
Sgt K Baker 3 Sqn, RAF St Athan
26
Mr J Hunter 6 Sqn, RAF St Athan
Mr S Millington DERA Farnborough (Senior Scientist Adhesives and Sealants)
Mr L McLaughlin LMC Chemical Ltd
BAe Brough, Customer Support, were invited to attend but chose not to send a representative.
7. Mr McLaughlin firstly briefed the attendees on the company products and then
demonstrated the use of Sky Restore on a sample of cured PRC 1422. Sky Restore was applied
by brush directly onto the PRC, and within 10 minutes the PRC showed signs of softening. After
agitation of the PRC with a brush and further waiting time of approximately 15 minutes, the PRC
was removed with a non-metallic scraper. The area was then cleaned with Sky Wipes and
neutralised using Sky Wash. Sky Wipes were also used successfully to remove PRC from tools
and skin.
8. A demonstration then took place on Hawk aircraft XX265 undergoing Major
maintenance. Sky Restore was liberally applied directly over cured PRC 1422 and masking tape
in the centre fuselage fuel tank skin area. PRC thickness in this area varies between 2mm to 8mm
depending on the initial application. After 15 minutes the PRC began to soften and was further
agitated with a paint brush. After 50 minutes both the tape and PRC was easily removed using a
non-metallic scraper. In some instances the PRC came cleanly away from the fuselage skin in
large strips. The area was then given a final clean using Sky Wipes and neutralised with Sky
Wash. Sky Restore was also used on a removed leading edge panel and effectively removed
cured PRC within 15 minutes.
9. It was noticeable that the Sky Restore has a particularly unpleasant smell, and in the
confined space of the fuel tank area appeared to emit a noxious odour. It would therefore be
necessary to use full protective equipment, including forced air breathing in confined spaces, such
as fuel tanks. When used in well ventilated areas, rubber gloves and goggles would be sufficient.
The DESAT investigation should establish exactly what health and safety implications will need to
be considered. Additionally it was felt that the liberal application of Sky Restore in the fuel tank
area had made the flooring very slippy and absorbent paper towelling should be positioned before
application.
10. Mr McLaughlin was made aware of our concerns regarding the unpleasant smell
associated with Sky Restore and agreed to investigate the possibility of reducing this odour
without effecting the formula of the product.
EFFECTIVENESS
11. All three Elixair products trialled were judged to have been effective, particularly Sky
Restore, which removed PRC in a fraction of the time taken by mechanical means. At present the
time allocation for removal of PRC for the fuel tank inspection is 300 manhours, and in one case
RAF St Athan informed this office that they expended 6 weeks on one particular aircraft. It is the
AEDIT's opinion that using Sky Restore to remove PRC for this inspection would reduce
timescales to approximately 24 manhours or 4 working days, a dramatic reduction in both time
and cost. It became obvious during the trial that the technique and method used to apply Sky
Restore to PRC in the fuel tank area had a significant effect on the time taken for removal.
27
CODIFICATION BY SM35(RAF)
12. SM35e(RAF) has codified the Elixair products as follows:
Sky Wipes (300) 33C/8030-99-5008568
Sky Wash (5 Lts) 33C/6850-99-3911135
Sky Wash (25 Lts) 33C/6850-99-9576783
Sky Restore (5 Lts) 33C/6850-99-7397555
Sky Restore (25 Lts) 33C/6850-99-6167913
To date, they have only agreed to purchase Sky Wipes and Sky Wash, which can be ordered
through Malcolm Hick at RAF Wyton, Tel 01480-444620. Sky Restore will not be available until
approval from DERA/DESAT is received.
CONCLUSIONS
13. The trial of Elixair products proved successful in effectively removing PRC from an
area on the aircraft in a fraction of the time normally taken using mechanical means. It therefore
clearly indicates a major cost saving.
14. From the success of the Hawk trial it is not unreasonable to assume that, providing a
positive response is received from DERA/DESAT, Sky Restore will be authorised by SM35(RAF)
and become available through normal supply channels.
RECOMMENDATIONS
15. Pending such approval, this office would recommend that the Elixair products known
as Sky Wipes, Sky Wash and Sky Restore be authorised for use on Hawk. It is further
recommended that the AEDIT are tasked to produce a procedure for the Topic 1B, Chap 7-00,
General Maintenance, the Topic 1C, Chap 15-10, Fuselage Structure, for these products prior to
their general use. This could be completed with the assistance of 6 Sqn, RAF St Athan.

ELIXAIR RANGE OF AVIATION PRODUCTS
(An alternative to MEK)
MEK is a solvent based, toxic, highly inflammable liquid which requires careful handling
and storage in a flame proof cabinet.
MEK Health and Safety data sheet calls up the use of masks, eye protection, rubber
gloves in addition to protective clothing when using in well ventilated areas. When using in
confined spaces the use of powered respirators is specified. See attached Health and
Safety Data Sheet.
For the past month, experiments have been carried out on the Airbus product using the
Elixair range of aviation products (Sky wipes, Sky wash and Sky Restore). I am now
happy to report that the experiment has been successful in terms of effectiveness and
cost.
SKY WIPES
This product is a solvent free wipe which is supplied in tubs of 300 wipes similar to baby
wipes. The product is impregnated with Sky wash and lanolin thus rubber gloves and
masks are not required.
The wipe has been most effective in removing excess sealant from aluminium assemblies,
and reports from the users state that it is more effective than MEK and reduces the time
taken to clean parts and assemblies. Please note the wipe is a cleaning product not a
degreaser as the lanolin will leave an invisible residue thus needs to be wiped with sky
wash to degrease. The product is approved by Boeing and is being used by Bae on
Airbus,
SKY WASH
This is the liquid agent used in the Sky wipe and is a degreaser. Application does require
the use of a cloth or brush and the wearing of rubber gloves is recommended. Sky wash is
non inflammable and solvent free thus usage is greatly reduced as no evaporation is
experienced.
SKY RESTORE
Product is in a gel form and is used for removing hard sealant deposits but can currently
only be used on detailed parts as experiments have not been completed to prove that
there is no erosion of the sealant under riveted parts of an assembly.
Airbus are currently carrying out tests thus approvals are expected shortly.
Product is FLAMMABLE and an irritant thus application requires the wearing of rubber
gloves, eye protection and protective clothing.
36
AIRBUS EXPERIMENTS IN HAMBLE
EFFECTIVENESS
All three products have been used on Airbus cleaning over the past month and operators
have been impressed.
Sky wipes have proven to be more effective than MEK in removing sealant and time taken
to clean assemblies has been reduced.
Sky wash has only been required when sealant is particularly wide spread and dried, thus
usage has been minimal.
Sky Restore has been used on cleaning aged detailed parts where the sealant is brittle
and hard. In comparison to cleaning with MEK, Sky Restore completes the job in a fraction
of the time.
COSTS
Airbus cleaning was selected for a controlled experiment to ascertain the usage cost
against MEK.
Volume Cost ?br>
Average monthly consumption of MEK 360 Litres 194.40
Average monthly consumption of mutton clothes 12 bundles 33.00
Average monthly consumption of Rubber gloves 6 pairs 8.70
Average monthly consumption of mask filters 8 40.48
Average monthly consumption of scotch brite 30 17.40
Average monthly consumption of brushes 36 15.84
Total monthly cost of cleaning material 309.82
Consumption of cleaning material using Sky products
Last months usage of Sky wipes 300 50.00
Last months usage of Sky wash 3 Litres 33.30
Last months usage of Sky Restore 0 0.00
Last months usage of mutton cloths 1 bundle 2.75
Last months usage of rubber cloves 2 pairs 2.90
Last months usage of mask filters 0 0.00
Last months usage of MEK 30 Litres 16.20
Last months usage of brushes 6 2.64
Last month usage of scotch brite 0 0.00
Total monthly cost 107.79
37
CONCLUSION
The experiment conducted on Airbus cleaning clearly indicates a major cost saving on
cleaning material (approx 66% reduction on monthly costs).
Whilst it would be beneficial to remove the use of MEK from the site, this is not practical
due to the requirement on Composite produces as specified by McDonald Douglas. MEK
at 54 pence a litre is also the cheapest product to use when cleaning and degreasing
equipment ie machine tools, engines, maintenance jobs etc, thus continued stocking of
this solvent is required.
In order to control the use of Sky products to aircraft cleaning, the ordering media will be
via indent (see attached sample) and be approved by Jim Beeden.

Standard Test Method for
Flash Point by Cleveland Open Cup
SCOPE The test method covers the determination of the flash point of all petroleum
products except fuel oils and those having an open cup flash below 79癈
(175癋).
SUMMARY OF TEST METHOD
The test cup is filled to a specified level with the sample. The temperature of the
sample is increased rapidly at first and then at a slow constant rate as the flash point
is approached. At specified intervals a small test flame is passed across the cup. The
lowest temperature at which application of the test flame causes the vapors above
the surface of the liquid to ignite is taken as the flash point.
Result:
Flash point: 56癈 (133癋)

Materials Engineering Laboratory Report
The Boeing Company MELR00-33
EVALUATION OF ELIXAIR SEALANT STRIPPER AND CLEANER
SOLUTIONS FOR COMPLIANCE TO BAC5725 PER BSS7219.
DATE: 5/2/00
AIRCRAFT: CH47
PARTNAME: CORROSION SPECIMENS-INTERGRANULAR AND END GRAIN
MATERIAL: ALUMINIUM 2024, 7050, AND 7075.
HEAT TREAT CONDITION: 2024-T3, 7050-T7451, AND 7075-T6
1.0 OBJECTIVE
The objective of this report was to evaluate aluminum corrosion specimens per
BSS7219 (Intergranular attack, Test Method) to the criteria of BAC5725 (Stripping
Organic Materials).
2.0 BACKGROUND
The RAF has requested permission to use ELIXAlR's SkyRestore stripper
and Sky Wash cleaner solutions to remove sealant materials from the CH-
47 during maintenance operations. Boeing was requested to evaluate these
materials for potential corrosion during use in removing sealant. Specimens
from three aluminum alloys (2024-T3, 7075-T6, and 7050-T7451) were used
in testing per BSS7219. The criterion for acceptance/rejection was obtained
from BAC 5725.
3.0 SPECIMEN PREPARATION, IMMERSION, AND EVALUATION
Six specimens were obtained by cutting aluminum from plate or sheet approximately
1 inch wide, 1 inch long, and 1/8 inch thick. One specimen from each alloy was
immersed for 30 minutes in each room temperature solution (SkyWash and
SkyRestore). Specimen thickness was measured before and after immersion. The
process qualification testing portion of BSS7219 requires the specimens to be
immersed for 30 minutes or the time necessary to remove 0.001 inch of metal per
surface, whichever is less. All specimens had less than 0.001 inch metal removed per
surface after immersion for 30 minutes.
The six aluminum
specimens were
examined visually without
magnification and the
results recorded in Table
1. The specimens were
then sectioned, and
mounted per BSS7219
(Figure 1). The cross
section of each

The Boeing Company MELR 00-33
specimen was metallographically examined at 200X magnification and the results
recorded in Table 1
4.0 TEST RESULTS
Visual examination of all six
specimens without magnification
did not reveal pitting or etching. All
six specimen cross-sections
examined at 200X magnification
complied with the criteria for
intergranular attack as described in
BAC5725 (Figure 2 is an exampIe
of evaluating Face A). Table 1 is a
summary of the results obtained
metallographically and visually.
5.0 CONCLUSIONS:
Aluminum samples of 2024-T3, 7075-T6, and 7050 T7451 exposed to ELIXAIR's
SkyRestore stripper and SkyWash cleaner solutions met the etching, pitting, and
intergranular attack criteria of BAC5725 when examined per BSS7219.
