Material Identification
PYRALUX is a registered trademark of DuPont.
Product Use
In keeping with DuPont's continuing commitment to safety and
the environment, we are providing this MSDS as a service to
our customers. This product is classified as non-hazardous
under OSHA's Hazard Communication Standard (29 CFR
1910.1200). Pyralux(R) products do create off-gases in
normal use. These off-gases are regulated, but are present
at such low levels during normal use that no hazardous
exposure is anticipated.
Tradenames and Synonyms
Standard Pyralux
Vapors from Pyralux LF Bond Ply
Vapors from Pyralux LF Coverlay
Vapors from Pyralux LF Copper-Clad Laminate
# Tradenames and Synonyms (Remarks)
Pyralux (R) LF is the product name of a family of products
consisting of flexible Copper Clad Laminates, Coverlay, Bond
Ply, and Sheet Adhesive.
The Clads are made of copper foil laminated to polyimide
film with an adhesive. The Coverlay and Bond Ply are made
of polyimide film with an adhesive, and the Sheet Adhesive
is just adhesive.

# Components (Remarks)
The quantity of vapors is estimated to be 10-15 lbs per
100,000 sq feet of adhesive.
Vapor evolution results are based on the percentage of
weight loss measured by Thermal Gravimetric Analysis (TGA).
This weight loss includes water vapor. The pounds of vapor
are not all "VOC's" as "definded" by the EPA for Clean Air
Act purpose.

HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Potential Health Effects
As a part of the hazard assessment process, DuPont has
conducted industrial hygiene studies to monitor the
potential exposure to the off-gases from this product during
normal use. Conclusions from the results of these studies
indicate that exposure levels during press lamination using
adequate ventilation were well below regulated limits (e.g.
an order of magnitude below the exposure limit). Tests run
for nuisance dust levels at a drilling/routing station with
vacuum exhaust also indicated exposure levels well below
regulated limits.
As a result of this test data, DuPont believes the potential
exposure to the vapors and dusts of this product is minimal.
Equipment used for lamination and curing must be adequately
exhausted. Consult the DuPont publication "Pyralux Safe
Handling". Additional information provided in "Handling &
Safety Considerations for the Pyralux PC Curing Process"
may also be helpful.

POTENTIAL HUMAN HEALTH EFFECTS OF OVEREXPOSURE:
Inhalation may cause irritation of the upper respiratory
passages, with sneezing, coughing and discomfort; or
temporary lung irritation effects with cough, discomfort,
difficulty breathing, or shortness of breath.
Inhalation, ingestion or skin contact may cause temporary
mild depression of the central nervous system with
dizziness, confusion, incoordination or drowsiness followed
by an asymptomatic period usually ranging from 12 to 24
hours. There are reports that suggest headache, hearing loss
and vertigo (dizziness) in workers exposed to less than 110
ppm of 1-Butanol.
Skin contact may cause redness of the skin and dermatitis
with itching or rash. Evidence from animal testing on some
vapor components suggests that skin permeation can occur in
amounts capable of producing the effects of systemic
toxicity.
Eye contact with high concentrations of vapors may cause eye
irritation with discomfort, tearing or blurring of vision.
Individuals with pre-existing diseases of the central
nervous system, liver or kidneys may have increased
susceptibility to the toxicity of excessive exposures.
Some compounds have been infrequently associated with skin
sensitization in humans.
Carcinogenicity Information
None of the components present in this material at concentrations
equal to or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH
as a carcinogen.
----------------------------------------------------------------------
FIRST AID MEASURES

First Aid
INHALATION
If inhaled, remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen.
Call a physician.
SKIN CONTACT
Flush skin with water after contact. Wash contaminated clothing
before reuse.

PRECAUTIONARY STATEMENTS FOR VAPOR CONDENSATE AND
VACUUM PUMP OIL:
WARNING! CAUSES EYE, SKIN AND RESPIRATORY IRRITATION.
Oil in vacuum pump will collect and concentrate less
volatile components. Condensate will contain higher
percentages of less volatile components. The less volatile
components may include acrylate monomers which may cause
delayed skin burns and may cause skin sensitization. Avoid
contact with eyes, skin and clothing. Avoid breathing mist
or vapor. Wash thoroughly with soap and water after
handling. Laminators and curing equipment used to process
PYRALUX(R) films should be designed with adequate
ventilation to exhaust these vapors from the workplace.
Vapors may condense on cold surfaces in exhaust ducts.
Check these surfaces for condensate build-up before
handling.
