A polybutylene glycol was reacted with toluene-2,4, di-isocyanate, resulting in a viscous liquid. Ten grams of this polymer was dissolved in 300 g of methyl ethyl ketone to which 1.1 g of 3,3'-dichloro-4,4'-diamino diphenyl methane (cross-linker) was added. The solution was applied to the PVF surface such that a thin film was formed.
