Geotextile/polyurethane composites based on blocked isocyanate compositions

摘要

The present invention relates to a geotextile/polyurethane composite prepared from one or more geotextiles and a blocked isocyanate composition and also to a process for preparing such composites. The inventive geotextile/polyurethane composites may find use as liners for canals and ditches for irrigation and wastewater, roof membranes, secondary containment, etc.
