          100-SS is a low viscosity,
        
        
          polyurethane resin designed to penetrate and
        
        
          stabilize loose or sandy soil when medium or high
        
        
          strength is required. It migrates through loose soil
        
        
          and into voids and reacts with moisture in the
        
        
          soil to form a polymer cement/soil matrix of high
        
        
          strength and durability. PolyLEVEL

          100-SS is
        
        
          resistant to most organic solvents, mild acids and
        
        
          bases, and micro-organisms. The polyurethane
        
        
          encapsulates loose soil, fills voids, and forms a
        
        
          solid, water-tight barrier.
        
        
          
            Unique Advantages
          
        
        
          • Contains no solvents
        
        
          • Very low viscosity for good penetration
        
        
          • Fast cure time controlled by catalyst ratio and
        
        
          moisture in the treated soil
        
        
          • Encapsulates and strengthens loose soil
        
        
          • Forms a water-tight barrier to stop water
        
        
          migration
        
        
          • Good resistance to chemicals
        
        
          • Excellent compressive strength (over 1,000
        
        
          psi in sand) and thermal stability

            Storage and Cleanup
          
        
        
          Activator MUST be agitated (shaken) before use.
        
        
          Flush equipment with acetone before and after
        
        
          use to clean equipment and remove moisture.
        
        
          If work area temperatures are low, heat the
        
        
          product to 55°F - 85°F to improve product
        
        
          performance. Do not use open flame as a heat
        
        
          source. Store chemicals between 55°F - 85°F
        
        
          in a dry atmosphere. Shelf life is 6 months, in
        
        
          original, unopened factory containers, under
        
        
          normal storage conditions of 55° to 85° F. Do
        
        
          not store in direct sunlight. Keep drums tightly
        
        
          closed when not in use. Cured product may be
        
        
          disposed of without restriction. Excess liquid
        
        
          material should be mixed together with sand or
        
        
          other absorbent material and allowed to cure,
        
        
          then disposed of in the normal manner.
        
        
          
            Safe Handling of Liquid Components
          
        
        
          Use caution in removing caps and bungs from the
        
        
          container. Loosen caps and bungs first to let any
        
        
          built up gas escape before completely removing.
        
        
          Avoid prolonged breathing of vapors. In case of
        
        
          chemical contact with eyes, flush with water for
        
        
          at least 15 minutes and get medical attention.

            Caution
          
        
        
          Polyurethane products manufactured or
        
        
          produced from this liquid system may present a
        
        
          serious fire hazard if improperly used or allowed
        
        
          to remain exposed or unprotected. The character
        
        
          and magnitude of any such hazard will depend
        
        
          on a broad range of factors which are controlled
