SECTION 2: Hazards identification

EFFECTS OF SINGLE OVEREXPOSURE: SWALLOWING: Small amounts transferred to the mouth by fingers during use, etc., should not injure. Swallowing large amounts may cause digestive discomfort. SKIN ABSORPTION: No evidence of adverse effects from available information. INHALATION: No evidence of adverse effects from available information. SKIN CONTACT: No evidence of adverse effects from available information. EYE CONTACT: Direct contact may cause temporary discomfort with mild redness, dryness, and irritation. EFFECTS OF REPEATED OVEREXPOSURE: No injury from silica or dust should occur during reasonable use. If use creates respirable particles, some respiratory system injury may occur. However, since the silica in this product is compounded into the polymer matrix, it is not expected to present the same hazards as neat silica.

Medical Conditions Generally Aggravated by Exposure

OVEREXPOSURE A knowledge of the available toxicology information and of the physical and chemical properties of the material suggests that overexposure is unlikely to aggravate existing medical conditions. SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH HAZAPD EVALUATION: None currently known. OTHER EFFECTS OF OVEREXPOSURE None currently known. 4. FIRST AID MEASURES EMERGENCY AND FIRST AID PROCEDURES: SWALLOWING: No emergency care anticipated. SKIN: Wash with soap and water. INHALATION: Short-term harmful health effects are not expected from vapor generated at ambient temperature. Obtain medical attention if discomfort persists. EYES: Immediately flush eyes with water and continue washing for at least 15 minutes. Obtain medical attention if discomfort persists. NOTES TO PHYSICIAN: There is no specific antidote. Treatment of overexposure should be directed at the control of symptoms and the clinical condition of the patient. Do not induce vomiting. Emesis of this material may prove difficult due to its high viscosity. Aspiration may cause lung damage. 5. FIRE FIGHTING MEASURES FLASH POINT (test method(s): >275ºF (Cleveland Open Cup) FLAMMABLE LIMITS IN AIR (by volume): LOWER: N/A UPPER:N/A EXTINGUISHING MEDIA: Apply alcohol-type or universal-type foams by manufacturers' recommended techniques for large fires. Use water spray, carbon dioxide, or dry chemical media for small fires. SPECIAL FIRE FIGHTING PROCEDURES: Do not direct a solid stream of water or foam directly into a pool of hot, burning liquid as this may cause frothing, and may intensify the fire. Use self-contained breathing apparatus when fighting fire in an enclosed area. UNUSUAL FIRE AND EXPLOSION HAZARDS: This product contains polydimethylsiloxane which can generate formaldehyde as a byproduct of oxidative thermal decomposition at temperatures greater than 150ºC (300ºF). See Section 10 for further information. 6. ACCIDENTAL RELEASE MEASURES STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: Spills should be contained with mechanical barriers. Transfer spilled material to a suitable container for disposal. WASTE DISPOSAL METHOD: Dispose of in accordance with all Federal, State, and local regulations. 7. HANDLING AND STORAGE PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE: Normal precautions common to safe manufacturing practice should be followed in handling and storage. Store below 90ºF Keep container closed, in a cool dry place S3/S7/S8 Any proposed use of this product in elevated-temperature processes should be thoroughly evaluated to assure that safe operating conditions are established and maintained. 8. EXPOSURE CONTROLS / PERSONAL PROTECTION OCCUPATIONAL EXPOSURE VALUES AND SOURCE: Silica, amorphous 10mg/m3- 8 hours TWA (ACGIH) 6mg/m3 8 hours TWA(OSHA,NIOSH) RFSPIRATORY PROTECTION: Use NIOSH approved respirator or self-contained breathing apparatus as needed to maintain personal exposure below established Occupational Exposure Values. VENTILATION: General (mechanical) room ventilation with local ventilation as needed to maintain exposure below established Occupational Exposure Values. PROTECTIVE GLOVFS: PVC-coated. EYE PROTECTION: Use safety goggles. 0THER PROTECTIVE EQUIPMENT: Eye bath and safety shower. 9.

STABILITY AND REACTIVITY DATA STABILITY: Stable. CONDITIONS TO AVOID: Contact with water or moist/humid air. INCOMPATIBILITY: Oxidizing materials can cause a reaction. HAZARDOUS COMBUSTION OR DECOMPOSITION PRODUCTS: Burning can produce carbon monoxide, carbon dioxide, oxides of silicon, and hydrocarbons. Carbon monoxide is highly toxic if inhaled; carbon dioxide in sufficient concentrations can act as an asphyxiant. Acute overexposure to the products of combustion may result in irritation of the respiratory tract. Traces of formaldehyde may be generated due to oxidative thermal decomposition at temperatures greater than 150ºC (300ºF). Exposure to formaldehyde can cause adverse effects such as skin and respiratory sensitization and eye and throat irritation. Formaldehyde is a potential carcinogen. Evaluate and control exposure to formaldehyde when warranted by conditions of use. HAZARDOUS POLYMERIZATION: Will not occur
