Abstract
The present invention provides an inventive arylene sulfide coating composition which exhibits enhanced hardness, inertness, abrasion-resistance, and durability. The, inventive composition comprises an arylene sulfide polymer resin and a ceramic microsphere filler. The inventive coating composition can be applied to a substrate in order to improve the degradation resistance of the substrate and provide an article of manufacture well suited for use in high temperature, abrasive, and/or corrosive environments.
Claims30
A method of improving the degradation resistance of a substrate comprising the step of coating at least one surface of said substrate with a layer of an arylene sulfide polymer coating composition, said arylene sulfide polymer coating composition comprising an arylene sulfide polymer coating resin and a ceramic microsphere filler incorporated in said arylene sulfide polymer resin, said ceramic microsphere filler being present in said coating composition in an amount in the range of from about 15 to about 40 parts by weight and said arylene sulfide polymer resin being present in said coating composition in an amount in the range of from about 50 to about 85 parts by weight such that said ceramic microsphere filler operates to improve the abrasion resistance of said coating composition.
An article of manufacture comprising:
- a substrate having at least one surface;
- and
- a layer of an arylene sulfide polymer coating composition coated on said surface, said arylene sulfide polymer coating composition comprising an arylene sulfide polymer coating resin and a ceramic microsphere filler incorporated in said arylene sulfide polymer resin, said ceramic microsphere filler being present in said coating composition in an amount in the range of from about 15 to about 40 parts by weight and said arylene sulfide polymer resin being present in said coating composition in an amount in the range of from about 50 to about 85 parts by weight such that said ceramic microsphere filler operates to improve the abrasion resistance of said coating composition.
