a thermally curable coating is spin applied to the surface of a lens through a process that comprises the following steps : preparing a thermally curable coating composition , spin applying the coating onto one surface of a lens , and curing the coating . the process combines the best features both of the spin application technique and a thermally cured coating to obtain high productivity with high yield in the application process yet provide superior coating properties without requiring stripping or other pretreatment steps , which have negative attributes . the process can also incorporate the use of either a thermoset or a thermoplastic primer to enhance the coating adhesion .
