Abstract
A glass fiber article having enhanced alkali resistance is described. The glass fiber has thereon a coating comprising zinc stearate and a film forming polymer with the coating being present in an amount of 1 to 60% by weight of solids based on weight of the glass fiber. The polymer is preferably initially in the form of a latex and is selected from the group consisting of acrylic terpolymers, vinyl acetate/ethylene copolymers, vinyl acetate/vinyl chloride/ethylene terpolymers, urethane polymers and epoxy polymers. The glass fiber is used at a rate of approximately 5% to 20% as reinforcing fiber in Portland cement and other alkaline cementitious composites. Such composites are also described, as is a method of imparting alkali resistance to glass fiber by applying such coating to the fiber.
