Abstract
Abstract A coating composition comprising a major amount of at least on fluorocarbon resin (A) and a minor amount of a property-improving additive (B) or (C); the resin (A) being: perfluoroalkoxy tetrafluoroethylene copolymer resin (PFA); ethylenechlorotrifluoroethylene copolymer resin (E-CTFE); ethylenetetrafluoroethylene copolymer resin (E-TFE); poly- (vinylidine fluoride) resin (PVDF); tetrafluoroethylenehexafluoropropylene copolymer resin (FEP); poly(chlorotrifluoroethylene) resin (CTFE); or a mixture of two or more of these resins; the additive being: (B) a poly(phenylene sulfide) (PPS); or (C) a nitride; an oxide; a diboride; or a carbide of silicon, zirconium, tungsten or boron.

Claim 3
Dependent Claim
17 words
A composition according to claim 1 comprising about 1 to about 40 wt. % of the additive.
Claim 4
Dependent Claim
19 words

Claim 7
Dependent Claim
52 words
An article according to claim 5 comprising a metal substrate having thereon a primer formed from a fused composition comprising PFA and about 1 to about 20 wt. % PPS and a top coating formed from a fused composition comprising PFA and about 1 to about 5 wt. % of additive (C).
Claim 8
Dependent Claim
55 words
An article according to claim 5 comprising a metal substrate having thereon a primer coating formed from a fused composition comprising PFA and about 1 to about 5 wt. % of additive (C) and a top coating formed from a fused composition comprising PFA and about 1 to about 5 wt. % of additive (C).
Claim 9
Dependent Claim
15 words
A molded article formed from the fused compositions of any of claims 1 to 4.
Claim 10
Dependent Claim
14 words

Claim 11
Independent Claim
79 words
A method for forming a fused coating from the composition of any of claims 1 to 4 comprising heating the composition to a temperature for a period of time no longer than a predetermined period of time, the said temperature being at least 14°C (25°F) below the temperature at which the resin of the composition in neat form can be fused completely by heating for no longer than the said determined period of time without substantially degrading the resin.
