The adhesive contains mechanically abrasive particles. Skin Harmful if absorbed through skin. Causes skin burns. May cause allergic skin reactions. Inhalation May be harmful if inhaled. Material is destructive to the tissue of the mucous membranes and upper respiratory tract. Ingestion Harmful if swallowed. Chronic Prolonged and repeated exposure to the uncured material used may cause sensitization and chemical burns. Long term accumulation of silver can lead to Argyria, which is an irreversible blue-grey discoloration of the skin.

Use water spray to cool containers. COUNTER INDICATION: Avoid use of water jet as extinguishing media. Material can form a very toxic aqueous solution with water. Prevent run-off from entering drains and waterways. Combustion Products Produces CO, CO2, ammonia, nitric acid, nitrogen oxides and other toxic fumes and smoke. Fire-Fighter Wear self-contained breathing apparatus for fire fighting General Information Toxic metal fumes may be released in fire. In presence of strong oxidizers and air, the silver metal powder may lead to an explosion. Note: The GHS codes and the GHS precaution statements are used. The format is GHS Codes: Statements. a) Closed cup value for lowest flash point component b) LFL = Lower Flammability [or Explosion] Limit (in volume %); UFL = Upper Flammability [or Explosion] Limit (in volume %) Personal Protection: See Section 8. Wear protective clothing. Avoid breathing the mist/vapors. Containment Remove all sources of ignition. Cleaning Collect spill in a sealable, chemical-resistant container with a spatula. Sprinkle inert absorbent compound onto spill remainder, then sweep into the container. Wipe residues with paper towel imbibed in isopropyl alcohol and place dirty towel in container. Wash spill area with soap and water to remove the last traces of residue. RECOMMENDATION: Use a plastic, stainless steel, or carbon steel container. Avoid containers with copper, aluminum, zinc, or galvanized surfaces since the waste material can slowly oxidize them. Disposal Dispose of spill waste according to Section 13. Page 5 of 13 Section 7: Handling and Storage Prevention P262: Do not get in eye, on skin, or on clothing. P261 + P271 + P284: Avoid breathing fume/vapors. Use only outdoors or in well-ventilated area. In cases of inadequate ventilation, wear respiratory protection. P270: Do not eat, drink, or smoke when using this product. RECOMMENDATION: Protect from heat. Do NOT process in a fashion that causes mist or fumes. Handling P280: Wear protective gloves/clothing/eye protection. RECOMMENDATION: Wear neoprene, butyl rubber, nitrile or other impervious gloves with breakthrough time greater than intended use period. P264: Wash hands thoroughly after handling. Storage P403 + P233+ P235: Keep Container tightly closed. Store in a well-ventilated area. Keep cool. RECOMMENDATION: Keep in a dry and clean area, away from incompatible substances. Note: The GHS codes and the GHS precaution statements are used. Section 8: Exposure Controls/Personal Protection Routes of Entry Eyes, ingestion, inhalation, and skin Engineering Controls Ventilation Keep airborne concentrations below exposure limits given in RECOMMENDATION: If the product is heated or worker is allergic, consider using a full mask with organic vapor cartridges. Personal Protective Equipment Eye protection Wear appropriate protective eyeglasses or chemical safety goggles. RECOMMENDATION: Use safety glasses with lateral protection (side shields). Skin Protection Wear appropriate protective clothing to prevent skin contact. RECOMMENDATION: Use of protective gloves in butyl rubber, neoprene, or other chemically resistant gloves. Continued on the next page Page 6 of 13 Respiratory Protection If exposed to mist, wear respirator such as a full-mask respirator. RECOMMENDATION: Consult your local safety supply store to ensure your respirator has filter cartridges appropriate for the ingredients listed in section 3 of this MSDS, and that the respirator is fitted to the employee by a professional. Ensure vapor cartridges are stored in sealed plastic bags when not being used. General Hygiene Considerations Wash hands thoroughly with water and soap after handling.
