Definitions
- This invention relates to non-stick coating compositions particularly useful on cookware.
- Poly (phenylene sulfide) resins are known for use in cookware coatings. Sometimes fluoropolymers and pigments, extenders or hardening agents such as titanium dioxide and aluminum dioxide are used.
- the present invention provides a coating composition comprising, in weight percentage ranges based on the solids content, about:
- the liquid carrier can be aqueous or organic.
- the poly(arylene sulfide) resin is preferably poly (phenylene sulfide) resin.
- the fluoropolymer is preferably polytetrafluoroethylene, but it can also be a perfluorinated copolymer of hexafluoropropylene and tetrafluoroethylene or a copolymer of tetrafluoroethylene and hydrocarbon ether monomers which have been completely substituted with fluorine atoms.
- the invention also comprises articles of cookware, such as bakeware, coated with such coating compositions and heated to remove the liquid carrier and more or less coalesce the coating.
- Aluminum flake can substantially increase the hardness at elevated temperatures of coating compositions of poly(arylene sulfide) resins and fluoropolymers, with optional titanium dioxide pigment.
- coating compositions have liquid carriers which are either aqueous or organic.
- Applicable arylene sulfide polymers include polymers of the type which are prepared as described in U.S. 3, 354 ,129. As disclosed in this patent, these polymers can be prepared by reacting a polyhalo-substituted cyclic compound containing unsaturation between adjacent ring atoms and an alkali metal sulfide in a polar organic compound. The resulting polymer contains the cyclic structure of the polyhalo-substituted compound coupled in repeating units through a sulfur atom.
- the polymers which are preferred for us e i n the coating procedure of this invention are those polymers having the repeating unit -R-S- where R is phenylene, biphenylene, naphthylene, biphenyl ether, or a lower alkyl substituted derivative thereof.
- R is phenylene, biphenylene, naphthylene, biphenyl ether, or a lower alkyl substituted derivative thereof.
- lower alkyl is meant alkyl groups having 1 to 6 carbon atoms such as methyl, ethyl, propyl, isobutyl, hexyl, and the like.
- the arylene sulfide polymers have melting temperatures within the range of about 205-483°C.
- the arylene sulfide polymer can be lightly cured, i.e., the molecular weight of the polymer can be increased by cross-linking or chain extension, e.g., by heating moderately, prior to application to the substrate.
- PPS polytetra fluoroethylene
- FEP hexafluoropropylene
- aqueous compositions preferably the aluminum flake has been reacted with phosphate ester or emulsified with fatty acid and neutralized to form a morpholine salt.
- Tipure R 900 TiO 2 pigment from Du Pont 4.24
- This premix is then mixed in the following proportions:
- the coating composition is applied to a substrate of any suitable material such as aluminum by suitable techniques such as spraying or roller coating.
- the coating is cured by heating 10 minutes at 400°C. This drives off the liquid carrier and coalesces into a desirable coating. Alternately, the coating can be cured at 370°C for 15 minutes, at 425°C for 5-7 minutes or under equivalent conditions .
- This premix is then mixed in the following proportions:
- Example 2 Two coating compositions were prepared and applied as in Example 1, differing in that one contained the aluminum flake of Example 1 while the other did not.
- the hardness of the two coatings was compared at elevated temperatures by the Erichsen technique described, inter alia, in the article by Weinmann entitled “Ein 14 Geratzzy Hartefug von Antrichen und to Schutz ⁇ berz ⁇ gen", published in Park und Lack, 68, No. 5, 323-326 (1962).
- the results in the following table demonstrate advantages of the invention.
