Section 1. Description

Urethane CombiAcc an aliphatic tertiary amine accelerator designed for the Urethane Combi. The Urethane CombiAcc can be used to modify the reactivity time of the grout.

Section 2. Ingredients

Section 3. Physical Data

Physical Form: Liquid Color: Pale Yellow Odor: Amine Odor Initial Boiling Point: 140 °F (60 °C) at 0.5mm Hg Freezing Point: -8 °F (-22 °C) Vapor Pressure: <0.1 mm Hg @ 68 °F (20 °C) Viscosity: 5 cps @ 68 °F (20 °C) Specific Gravity: 0.921 @ 68/39.8 °F (20/4 °C) Bulk Density: 7.68 lbs/gal H2O Solubility: not soluble in water. Other Solubilities: Miscible with most organic solvents (ketones, benzene, waxes, and oils).

Section 4. Fire and Explosion Data

Flash Point: >300 °F (>149 °C) Extinguishing Media: For small fires, use dry chemical, carbon dioxide (CO2). For large fires, use fog or regular foam. Unusual Fire or Explosion Hazards: Vapors are heavier than air and may collect in low lying areas. Container may explode in heat of fire. Exposure to flames or arc welding can produce highly toxic gases due to the thermal decomposition or combustion of the product. (see section 5) Fire Fighting Procedures: Since fire may produce toxic thermal decomposition products, wear a self-contained breathing apparatus with a full face piece operated in pressure-demand or positive-pressure mode. Apply cooling water to sides of container until well after fire is out. Do not release fire water runoff to sewers or water ways.

Section 5. Reactivity Data

Stability: Is stable at room temperature in closed containers under normal storage and handling conditions. Hazardous Polymerization: can not occur. Incompatibility: Is incompatible with strong acids and strong oxidizers. Hazardous Products of Decomposition: Thermal decomposition can produce carbon monoxide (CO) and oxides of nitrogen.

Section 6. Health Hazards Data

FIRST AID PROCEDURES Eyes: Immediately flush eyes with a directed stream of water for at least 15 minutes, forcibly holding eyelids apart to ensure complete irrigation of all eye and lid tissue. GET IMMEDIATE MEDICAL ATTENTION TO PREVENT EYE DAMAGE. Skin: Quickly remove contaminated clothing. Wash contaminated areas with plenty of soap and water. A soothing ointment may be applied to irritated skin after thorough cleansing. SEEK MEDICAL ATTENTION. Inhalation: Remove exposed person to fresh air and support breathing if necessary. Ingestion: Do not induce vomiting. Give 1 to 2 cups of milk or water to drink. If vomiting is inevitable, prevent aspiration by keeping the victims head below the knees. DO NOT GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON. GET MEDICAL ATTENTION IMMEDIATELY. Exposure Limits: have not been established for this material. Dermal LD50: 4.29 ml/kg (rabbit) Oral LD50: 1.58 ml/kg (rats)

Section 7. Employee Protection Recommendations

Goggles: Wear a face shield (8 in. minimum) per OSHA eye and face protection regulations (20 CFR 1910.133). Respirator: Follow OSHA respirator regulations (29 CFR 1910.134) and if necessary wear MSHA/NIOSH - approved respiratory. In confined spaces use supplied air respirator or self contained breathing apparatus with a full face piece operated in pressure demand or positive-pressure mode. Clothing: Wear chemically protective gloves, boots and aprons to prevent repeated or prolonged skin contact. Viton, neoprene and nitrile rubber are recommended materials for protected gear. Ventilation: Provide general and local exhaust ventilation systems to prevent hazardous accumulation of vapors. Others: Never drink, eat or smoke in work areas. Practice good personal hygiene after using this material and before eating, drinking and smoking.

Section 8. Spill and Leak Procedures

Notify safety personnel, isolate and ventilate the area. Stay up wind. Remove all ignition sources. For small spills, absorb with sand or other absorbents and place in suitable containers for later disposal. For large spills, dike ahead for a later disposal or reclamation. For disposal, follow applicable federal, state, and local regulations.

Section 9. Special Precautions

Storage: Prevent physical damage to containers. Store in lined steel or plastic drums, in a cool, dry, well ventilated area, away from sunlight and incompatibles, and food.

Section 10. Transportation

DOT Shipping name: Alkylamines, n.o.s. DOT Hazard Class: 8 ID No.: UN2735 DOT Packaging Group: II    Packaging Instr.: 808 (passenger aircraft) DOT Label: Corrosive
