Leak-Proof SS
PU Soil Stabilization Grout
(Activator sold seperately)
DESCRIPTION 
Leak-Proof SS is a soil stabilizer designed to increase the bearing capacity of sandy ground to increase the strength. When Leak-Proof SS comes into contact with water, it expands quickly to form a polyurethane foam. The speed of reaction can be changed by altering the amount of accelerator used and the temperature at which it is used. PHYSICAL PROPERTIES* 
Part A Accelerator Appearance Dark Brown Clear Colourless Liquid Viscosity 25oC, cps 25 5 ASTM D-1638 Solids, wt% 100 100 ASTM D-1010 Specific gravity @25oC 1.15 ASTM D-1638 Flash Point >142oC >160oC ASTM D-93 Mix Ratio (A:Accelerator) 100 1-5% Pot Life --------- 25 Seconds to 8 minutes ------------ Mixed Viscosity @ 5% Accelerator 25oC, cps….. 265 TYPICAL FILM PROPERTIES* 
Tensile Strength, psi 170 ASTM D-3574 Compression Strength psi 1648 ASTM C-190-1963 Bending Strength, psi 369 Shearing Strength, psi 184 Toxicity Non-Toxic Packaging:
Five (5) gallon (18.9 ltr.) metal pail (46Lbs or 20kg), closed head with flex spout. CAUTION - pH NOTICE: All water that is to be used to "activate" Polyurethane Grouts must be in the range of ph 3 - 10 for proper chemical reactions of the product to take place. Clean Up: All equipment must be cleaned immediately after use. Thorough and repeated flushing is required using Leak-Proof PUMP CLEANER. The equipment lines should then be filled with Leak-Proof PUMP CLEANER to eliminate air/moisture from the lines. Cured material should be mechanically removed. Safety and Toxicity: Leak-Proof SS is an MDI based single component polyurethane. These recommendations are common with all MDI based polyurethanes. Within the generic group of polyurethane polymer technology the MDI based polyurethanes are considered the safest in terms of safety and toxicity. Isocyanates are designated substances and are capable of producing a severe allergic breathing problem in some people. If any difficulty at all with breathing is experienced the person should immediately vacate the work area. Particular care should be taken to avoid mixing and application in confined areas. Avoid breathing vapours at any time. Precautions must be taken to prevent prolonged or repeated skin contact and it is essential to protect the eyes from splashes.
Repeated skin contact can also cause sensitization. Protective clothing, rubber gloves and chemical goggles should be worn when working with these products. A facemask with organic cartridge and a particulate filter is usually adequate. Air supplied mask is suitable for use in confined areas.
Refer to MSDS for details. MSDS is availble on request.
NOTE:
Although reactive chemicals are needed to form Leak-Proof SS the final cured material is a non-toxic polyurethane foam.
Storage: Store in heated area and on pallets. Do not allow products to freeze. Shelf life in unopened containers is one year. Once opened, then dependent on humidity, shelf life may be reduced to as little as 3 months.
