Abstract
A non-yellowing urethane adhesive based on a polyurethane prepolymer which is prepared by reacting a specific combination of polyhydroxy compounds and an isocyanate compound. The polyhydroxy compounds include a polyalkylene ether diol, a polyalkylene ether triol, and a polyester polyol. The combination of these polyhydroxy compounds and an isocyanate compound results in an adhesive composition which has exceptionally good resistance to high temperature, humidity, and sustained UV radiation, particularly when applied to fabric-like materials.
