3. Hazard Identification
Base: Base resin is flammable, harmful by inhalation and irritating to eyes and skin.
Strongly exothermic polymerisation may be initiated by heat, peroxides or
other free radical generators.
Hardener: The hardener is an oxidising substance, may cause fire. Irritating to the eyes
and may also cause sensitisation by skin contact.
4. First Aid Measures
Inhalation: In case of drowsiness or sickness remove to fresh air, keep patient warm and
at rest. If unconscious, turn to the recovery position. Seek medical assistance.
Skin Contact: Promptly remove contaminated clothing and wash the affected area with
plenty of soap and water to ensure all traces of product are removed, then
rinse thoroughly. Any contaminated clothing must be thoroughly cleaned
before re-using. Seek medical advice if irritation persists.
Eye Contact: Flush with copious amounts of clean water for at least 15 minutes, with the
eye lids held open. Seek medical attention.
Ingestion: Wash out mouth with water. Keep patient at rest and obtain medical attention.
DO NOT INDUCE VOMITING.
5. Fire Fighting Measures
Suitable Extinguisher Media: Alcohol-resistant foam, dry powder, carbon dioxide or
sand.
Unsuitable Extinguishing Media: Water, halons.

Exposure Hazards: May give off toxic fumes if heated or involved in a fire,
including carbon monoxide, carbon dioxide, benzoic
acid, benzene and phenyl benzoate.
Special Protective Equipment: Full face, positive pressure, self-contained breathing
apparatus and full protective clothing.
6. Accidental Release Measures
Personal Precautions: Wear protective equipment as specified in Section 8.
Do not eat, drink or smoke. Avoid contact with skin
and eyes. Avoid breathing vapours and dust.
Eliminate all ignition sources.
Environmental Precautions: Eliminate all ignition sources. Keep people and
animals away. Prevent entry into drains, sewers and
watercourses. If spillage enters drains leading to
sewerage works inform the local water company. If
spillage enters rivers or watercourses inform the
Environment Agency.
Spillages: Cordon off area. Absorb/contain spillage using inert
absorbent granules, sand or earth. Transfer collected
material to heavy-duty plastic/steel drums and keep in
a well ventilated place for subsequent safe disposal.
See Section 13.
7. Handling and Storage
Handling: No specific precautions required when handling
unopened containers; follow any relevant manual
handling guidance. Refer to Sections 6 and 8 if
exposure to product is possible. Take precautionary
measures against static discharges. Wash thoroughly
with soap and water before eating, drinking or
smoking, and after work
Storage: Store in original containers in a well ventilated area
away from heat, sunlight, ignition sources or open
flame. Keep away from reducing agents (eg amines),
acids, alkalis and heavy metal compounds (eg
accelerators, driers, metal soaps).
8. Exposure Controls / Personal Protection
Occupational Exposure Standards: Styrene - 8 hour TWA 100ppm, 15 min STEL 250ppm
MEL.
This exposure limit must not be exceeded at any time
during the exposure period.
3
Talc - 8 hour TWA 1mg/m (respirable) OES.
3
General Dust - 8 hour TWA 10mg/m (total inhalable),
3
4mg/m (respirable) OES.
While the base component contains talc and general
dusts, which have an Occupational Exposure
Standards assigned to them, these materials are not
present in powder form and therefore do not present
an inhalation hazard.
3
Dibenzoyl Peroxide - 8 hour TWA 5mg/m OES.
3
Diisobutyl Phthalate - 8 hour TWA 5mg/m OES.

While the hardener component contains dibenzoyl
peroxide and diisobutyl phthalate, it is very unlikely
that these Occupational Exposure Standards would
be exceeded under foreseeable conditions of use.
Engineering Control Measures: Refer to any applicable COSHH assessments.
Engineering controls should be used where
practicable in preference to personal protection and
may include physical containment and good
ventilation.
Respiratory Protection: If levels of styrene exceed the above limits, or in the
unlikely event that the limits for dibenzoyl peroxide or
diisobutyl phthalate are exceeded, use an approved
respirator fitted with an appropriate gas cartridge
(organic substance). All items must conform to EN149
and should be suitable for the levels of contamination
present in the workplace.
Hand Protection: Wear Neoprene, Nitrile or PVC gloves or gauntlets.
These must be manufactured to EN374. The material
breakthrough time should be stated by the glove
manufacturer, and must be observed at all times.
Eye Protection: If eye contact with the product is likely chemical
resistant goggles conforming to BS 2092 should be
worn.
Body Protection: Wear suitable impervious, chemical resistant overalls.
Foot Protection: Wear chemical resistant safety footwear.
Hygiene Measures: Handle in accordance with good industrial hygiene
and safety practice.

10. Stability and Reactivity
Stability: Base: Stable under normal conditions (see Section 7).
Hardener: A dangerous self-accelerating decomposition reaction
and, under certain circumstances, explosion or fire
can be caused by direct contact with incompatible
substances or by thermal decomposition at and above
o
the SADT of 50 C.
Materials to Avoid: Base: Strong oxidising agents.
Hardener: Acids, alkali, heavy metals and reducing agents.
Avoid contact with rust, iron and copper. Do not mix
with peroxide accelerators. Do not mix with reducing
o
agents. Avoid temperatures above 25 C. Avoid shock
and friction.

combined the harmful constituents will react to form an inert product.
Both styrene and dibenzoyl peroxide are readily biodegradable.
Dibenzoyl peroxide (78%)
