Section 1. Description

The Reinforcing Agent is a water-based emulsion that can be used with a wide variety of chemical grouts. The Reinforcing Agent reduces shrinkage and improves the mechanical strenght of the cured gel. The cured gel will also show a better chemical resistance. The Reinforcing Agent is to be added to the water side of the Urethane Gel HF.

Section 2. Ingredients

Section 3. Physical Data

Physical Form: Liquid Color: Milky White Odor: Slight Odor Boiling Point: 212 °F (100 °C) Vapor Pressure: 17.5 mm Hg @ 20 °C Specific Gravity: 0.980 - 1.040 @ 68/39.8 °F (20/4 °C) H2O Solubility: soluble in water.

Section 4. Fire and Explosion Data

Flash Point: N/A 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 toxic gases due to the thermal decomposition or combustion of the product, once the water is evaporated. (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: Will not occur. Incompatibility: None known. Hazardous Products of Decomposition: Thermal decomposition can produce carbon monoxide (CO), oxides of nitrogen and other unknow gases.

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 victim's head below the knees. DO NOT GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON. GET MEDICAL ATTENTION IMMEDIATELY. Exposure Limits: Ingestion: oral LD50 for rats is >5000 mg/kg for similar material.

Section 7. Employee Protection Recommendations

Goggles: Use safety glasses. Respirator: Because of the low vapor pressure, ventilation is usually sufficient. Local exhaust ventilation may be necessary for some operations. Clothing: Wear chemically protective gloves, boots and aprons to prevent repeated or prolonged skin contact. 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 suitable containers for later disposal. Water may be used for final cleaning of the affected area. 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: Store at temperatures between 40 °F and 110 °F. May coagulate if frozen at 32 °F (0 °C). Material may develop bacteria odor on long-term storage. No known safety problems.
