ABSTRACT:
A process and composition for treating glass fibers for use as reinforcement of cementitious materials. The glass fibers are first sized with a size composition containing cationic fiber forming organic polymer and then a second coating containing an anionic film-forming organic polymer is applied to the glass fibers whereby the cationic and anionic polymers react to form a thin film on the glass fiber surfaces. The resulting glass fibers have good wetting and dispersibility characteristics for use as reinforcement of cementitious materials.
