Section 1. Description

Urethane GEL HFacc an aliphatic tertiary amine accelerator designed for the Urethane GEL HF. The Urethane GEL HFacc 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: Ammoniacal Odor Boiling Point: >418 °F (214 °C) at 760 mm Hg Freezing Point: -13 °F (-25 °C) Vapor Pressure: <0.2 mm Hg @ 68 °F (20 °C) Viscosity: 5 cps @ 68 °F (20 °C) Specific Gravity: 1.05 @ 68/39.8 °F (20/4 °C) Bulk Density: 8.345 lbs/gal H2O Solubility: soluble in water. Reacts slowly with water to liberate CO2 gas Other Solubilities: Miscible with most polar organic solvents (ketones, alcohols and glycols).

Section 4. Fire and Explosion Data

Flash Point: 225 °F (107 °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. May form peroxides of unknown stability.

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 MEDICAL ATTENTION 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: 2000 mg/kg (rabbit) Oral LD50: 700 mg/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: Because of the low vapor pressure, ventilation is usually sufficient to keep the vapors below the TLV at room temperatures. Exceptions are when the material is sprayed or heated. If airborne concentrations would exceed the TLV, follow OSHA respirator regulations (29 CFR 1910.134) and if necessary wear MSHA/NIOSH-approved respirator. If inadequate ventilation 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.

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 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 steel drums, in a cool, dry, well ventilated area, away from sunlight and incompatibles, and food.
