Glass fiber-treating agent and glass fiber-treating composition

摘要

A glass fiber-treating agent comprising (A) 5-95% by weight of an acetylene glycol or an ethylene oxide and/or propylene oxide adduct of acetylene glycol and (B) 5-95% by weight of a silicone surfactant. The agent functions to reduce dynamic and static surface tension and contact angle and offers excellent wetting, penetrating and antifoaming properties when glass fibers are treated therewith.
