ABSTRACT:
A glass fiber forming size utilized to produce glass fiber strands is described in which the forming size is an aqueous mixture of polyvinyl acetate, fatty acid lubricant, methacrylato chromic chloride and gamma (ethylene diamine) propyl trimethoxy silane, the mixture being adjusted to pH between 6.1 and 6.5. The size composition is applied to glass fibers during forming. The strands produced utilizing this forming size find particular utility when formed into roving and produce a particularly effective gun roving product.
