Abstract
A flexible epoxy coated fabric has good hand, good wear resistance, good hydrolytic resistance, and good ultraviolet light resistance. An optional but desirable binder is a true coating and not an impregnation of the fabric in that at least 50 percent of the binder material resides on the surface of the fabric. A flexible epoxy material is utilized as a coating and generally has an intermediate hydrocarbon portion having at least 25 carbon atoms for each chain. The fabric is suitable as a substitute for leather in clothing, and upholstery as in automotive upholstery.
Claims21
An epoxy coated fabric, comprising:
- a fabric support coated with a flexible epoxy resin, said resin consisting essentially of an epoxy resin having an apparent bending modulus of from about 20 to about 2,000 psi as measured by ASTM D47-86 or an admixutre of said epoxy resin with up to 10% by weight of a rigid epoxy resin.
An epoxy coated fabric, comprising:
- a fabric support coated with a flexible epoxy resin, wherein said flexible epoxy resin is (1) derived from an epoxy having the formula ##STR2## wherein n, independntly, is a whole number of at least about 25 for either of the chains or (2) an admixture of that epoxy resin with up to 10% weight of a rigid epoxy resin.
A flexible epoxy coated lamina, comprising:
- a first discrete layer comprising a fabric;
- a second discrete layer comprising a flexible binder;
- and
- a third discrete layer comprising a flexible epoxy, said binder layer adhering said flexible epoxy layer to said fabric layer and said flexible epoxy resin is (1) derived from an epoxy having the formula ##STR3## wherein n, independently, is a whole number of at least about 25 for at least one of said chains or (2) an admixture of that epoxy resin with up to 10% by weight of a rigid epoxy resin.
