Abstract:
A polyurethane geotextile composite comprising a geotextile impregnated with a polyurethane-forming reaction mixture with adjustable mix viscosity comprising:a) a liquid polyisocyanate having an isocyanate group content of at least 10% by weight; b) an isocyanate reactive component comprising a polyether polyol having from 2-6 hydroxyl groups and a number average molecular weight of from 250 to about 8,000 and 0-10% by weight, based on total weight of b), of a low molecular weight diol or triol having a hydroxy equivalent weight of from about 31 to 99; c) a catalyst for catalyzing the reaction between hydroxyl groups and isocyanate groups; d) from 0.2 to about 5.0 parts by weight per hundred parts by weight of isocyanate-reactive component b) of a viscosity adjusting component; and optionally, e) filler; which has cured.
