Non-stick coating and method of forming same
Non-stick coatings for use on a flexible substrate include a fluoropolymer, an acrylic polymer, and a polyol and/or diol. The ratio of acrylic polymer to polyol and/or diol is between about 90:10 and about 10:90 by weight, preferably about 50:50. The ratio of acrylic polymer and polyol or diol to fluoropolymer is preferably about 100:60 by weight.
1. A non-stick coating formulation comprising:
a. an acrylic polymer,
b. an alcohol selected from the group consisting of a diol, a polyol, and mixtures thereof, and
c. a fluoropolymer, and
d. a cross-linking agent for cross-linking the acrylic polymer with the alcohol; wherein the alcohol comprises a polyurethane polyol.
