INGREDIENT NAME CAS NUMBER WEIGHT % EINECS/ELINCS Acrylic adhesive Not known < 95% Not known Silver 7440-22-4 < 10% 231-131-3 Trace impurities and additional material names not listed above may also appear in Section 15 near the end of the MSDS. These materials may be listed for local "Right-To-Know" compliance and for other reasons. However, we have never found any evidence for trace contaminants in these adhsive materials.
Emergency overview:
A silver filled adhesive layer. Not considered hazardous under normal usage.
Can release irritating and/or toxic vapors at elevated processing
temperatures or if involved in a fire. Caution should be exercised
about not permitting the film to come in contact with a hot plate
that is going to take the acrylic beyond the point where vapors
are released from the film.
Potential Health Hazards:
Skin: Not considered hazardous but constant contact with this
product could lead to some skin irritation.
Eyes: Not considered hazardous but if eye contact should occur,
wash with fresh water for 15 minutes.
Inhalation: Not a route of exposure under normal usage. Elevated
processing temperatures may release irritating vapors,
and large amounts of cutting could generate irritating
particulates, but mainly coming from the release papers,
not from the "silver-filled" adhesive.
Ingestion: Not a route of exposure. Ingestion of silver may cause
irritation of the digestive tract; effects may be cumulative,
causing abdominal pain, rigidity, convulsions and shock.
Chronic effect: Chronic inhalation or ingestion of silver salts may cause
argyria, with permanent blue-gray discoloration of eyes, skin,
mucous membrandes, and internal organs.
Target Organs [2440-22-4]: Kidneys
Ingredients found on one of the OSHA designated carcinogen
lists are listed below.
Carcinogenicity - NTP: NO
Carcinogenicity - IARC: NO
Carcinogenicity - OSHA: NO
Explanation Carcinogenicity: NONE
Take proper precautions to ensure your own health and safety before
attempting to rescue and providing first aid. For specific information
refer to the Emergency Overview in Section of this MSDS.
Skin: If molten material contacts the skin, immediately flush the
skin with large amounts of water to cool the affected tissue
and polymer. Do not attempt to peel polymer from skin. Get
medical attention immediately.
Eyes: None needed under normal usage. If material comes into contact
with the eye, flush eyes with water while holding eyelids apart
to ensure complete irrigation.
Inhalation: None needed under normal usage. If exposed to vapors at
elevated processing temperatures, remove to fresh air.
Ingestion: None needed under normal usage.
Advice to physician: Treat symptomatically and supportively.
Flammable Properties
Flash Point: Not applicable.
Flash Point Method: Not applicable.
Autoignition Temperature: Not determined.
Upper flame limit (volume % in air): Not applicable. Non-volatile solid.
Lower flame limit (volume % in air): Not applicable. Non-volatile solid.
Flame propagation rate (solids): Not determined.
OSHA Flammability class: Not determined.
Extinguishing Media: Carbon dioxide, dry chemical foam, water or
other agents as appropriate for materials in
surrounding fire.
Unusual Fire and Explosion Hazards: Gaseous products may be evolved
if the film is heated to very high
temperatures and they should be
regarded as hazardous. This could
also include organo-silver compounds.
Special Fire Fighting Precautions/Instructions:
Wear NIOSH/MSHA approved positive pressure self-contained breathing
apparatus and full protective clothing.
In Case of Spill or Other Release: (Always wear recommended personal protective equipment.) Collect and place in a solid waste container. Spills and releases may have to be reported to Federal and/or local authorities. See Section 15 regarding reporting requirements.
Normal Handling: Always wear recommended personal protective equipment
such as laboratory safety glasses. Use normal personal
hygiene and good housekeeping.
Storage Recommendations: Store in a cool, dry area, preferably
refrigerated, away from direct heat
or sunlight.
Engineering Controls: General room ventilation is adequate for normal
cutting and shaping of the film.
Personal Protective Equipment
Skin Protection: Not normally required. Use heat resistant gloves if
handling melted material.
Eye Protection: As a general practice in manufacturing areas, safety
glasses that conform to ANSI Z87.1 should be worn.
Respiratory Protection:
Under normal usage, not normally required. A NIOSH/MSHA approved
respirator should be worn in areas where the PEL/TLV is exceeded.
Additional Recommendations: None.

Other Exposure Limits for Potential Decomposition of Products
Appearance: Silver-filled adhesive layer Physical state: Solid, sticky adhesive layer. Odor: None. Specific Gravity (water = 1.0): Not known Solubility in Water (weight%): Negligible. pH: Not applicable. Boiling Point: Not applicable. Melting Point: Not known Vapor Pressure: Negligible at room temperature. Vapor Density (air = 1.0): Not determined. Evaporation Rate: Not determined. % Volatiles: Negligible. Flash Point: Not applicable. Flash point method and additional flammability data are found in Section 5.
Normally Stable? (Conditions to Avoid) Normally stable. Avoid exposure to open flame or temperatures exceeding recommended processing temperatures. The maximum temperature to which the film can be exposed will vary with exposure (dwell) time. Any such heating should be done under exhaust fume hood conditions and the breathing of vapors should be avoided. Incompatibilities: Alkali metal complexes and organic amines. Highly chlorinated-fluorinated solvents, nitrogen tetroxide and chlorine gas tend to plasticize the film. Silicones tend to induce stress cracking. Hazardous Decomposition Products: Thermal decomposition products may include silver vapors, organo-silver compounds, hydrogen chloride, hydrogen fluoride, carbon monoxide, carbon dioxide and combustion by-products (oxidized and non-oxidized hydrocarbons). Hazardous Polymerization: Will not occur.
RTECS# [7440-22-4]: VW3500000 LD50/LC50: Not available Immediate (Acute) Effects: Not determined. Delayed (Subchronic and Chronic) Effects:Chronic inhalation or ingestion of silver salts may cause argyria, with a permanent blue-gray discoloration of the eyes, skin, mucous membranes and internal organs. Other Data: None.
Exotoxicity: Exotoxicity is expected to be low based on the near zero water solubility of the polymer and also, metallic silver. Material is considered inert and not expected to be biodegradable or toxic. Bioaccumulation: Not expected to occur.
RCRA Is the unused product a RCRA hazardous waste if discarded? No. Other Disposal Considerations: Dispose of in compliance with Federal, state and local government regulations. Usually considered an inert packaging material that can be recycled or landfilled. Incineration is not a preferred disposal method because of the possible formation of hydrogen chloride and hydrogen fluoride. The information offered here is for the product as shipped. Use and/or alterations to the product such as mixing with other materials may significantly change the characteristics of the material and alter the RCRA classification and the proper disposal method.
US DOT Hazard Class: Not regulated. US DOT ID Number: Not applicable, none assigned.
Toxic Substances Control Act (TSCA)
TSCA Inventory Status: Listed on the TSCA Inventory.
