Abstract:

The durability of polybutadiene-polyurethane joints or glass or metals in water at room and elevated temperatures was studied. The effects of silane pretreatment of the surface and of surface morphology on adhesion were examined. The durability of the joint was related to the number of chemical bonds that could form between the polyurethane and the surface and to the type of surface treatment given to the surface. Proper treatment led to significant enhancement of durability of the joints. The polyurethane was prepared from ARCOs hydroxyterminated polybutadiene R-45HT, toluene diisocyanate, trimethylolpropane, and N,N-bis2-hydroxypropyaniline. Author
