  • Abrasion-resistant and low friction coating compositions
    Patent number: 5674951
    Abstract: Coating compositions are disclosed which use a polyoxetane polymer having CH.sub.2 --O---CH.sub.2 --R.sub.f side chains where R.sub.f is a highly fluorinated alkyl or polyether. The coating compositions use polyisocyanates to create isocyanate terminated polymers from the poly(oxetanes) and from various polyols from alkylene oxides or polyester polyols. These can be reacted together to form block copolymer structures or can be linked together when the coating is crosslinked. A preferred method is to use blocked isocyanate groups. Another preferred embodiment is to use the composition as a abrasion resistant coating for glass run channels.
