Abstract
A method for coating arylene sulfide polymers onto substrates by applying to the surface of the substrate a sufficient amount of a compound that acts as an aid in obtaining a smooth surface of arylene sulfide polymer over the substrate, applying a sufficient amount of arylene sulfide polymer to form a surface coating, and raising the temperature of the coated surface sufficiently to cure the coating of arylene sulfide polymer. In one embodiment, the compound acting as an aid in obtaining a smooth surface is applied as a film over the substrate surface and this film is overcoated with poly(arylene sulfide). In another embodiment, the aid for obtaining a smooth surface is applied over the substrate as part of a powdered mixture containing both the compound and powdered poly(arylene sulfide).
Claims9
A method for coating arylene sulfide polymer onto a substrate comprising:
- (a) applying to the surface of said substrate in an amount sufficient to effect on the surface of said substrate a film consisting essentially of at least one compound from the group consisting of:
- (1) hydrocarbons and polyhydrocarbons selected from the group consisting of mineral oil, petrolatum, paraffin wax, montan wax, ozocerite, Fischer-Tropsch wax, and normally liquid and normally solid polymers of aliphatic mono-1-olefins;
- (2) fatty alcohols containing from about 14 to about 30 carbon atoms per molecule;
- (3) esters of fatty alcohols containing from about 12 to 30 carbon atoms per molecule;
- (4) naturally occuring plant and animal waxes comprising mixtures of fatty alcohols, esters, and hydrocarbons;
- (5) esters of polyhydric alcohol;
- and
- (6) fatty acid amides;
- (b) applying poly(arylene sulfide) as an overcoating on said film of step (a) in an amount sufficient to form a surface coating;
- and
- (c) curing at a temperature in the range of about 400.degree. F. to about 900.degree. F.
