ABSTRACT:
A method for applying a thin abrasion resistant polyurethane coating while minimizing exposure to volatile free isocyanate is disclosed. The method involves forming a hydroxy-terminated prepolymer which is subsequently crosslinked using a relatively non-volatile triisocyanate, and applying the material by flow coating or dip coating techniques, rather than spraying, in order to minimize volatilization.
