SILANE COUPLING AGENT, SIZING AGENT COMPRISING THE SAME, GLASS FIBER BUNDLE COATED WITH THE SAME SIZING AGENT AND POLYESTER RESIN COMPRISING THE SAME GLASS FIBER BUNDLE

摘要

PROBLEM TO BE SOLVED: To obtain a silane coupling agent capable of suppressing the static electricity of glass fibers from generating and providing a glass-fiber reinforced polyester resin having excellent water resistance and physical characteristics, a sizing agent comprising the silane coupling agent, a glass fiber bundle coated with the sizing agent and the glass-fiber reinforced polyester resin comprising the glass fiber bundle. SOLUTION: This silane coupling agent is obtained by reacting one mol of a silane compound represented by the following general formula (1) NH2(R1- NH)n-R2-Si-(OCxH2x+1)3 (1) [R1 and R2 are each an alkylene group; n is 0-5; and x is 1-3] with 2 mol of glycidyl (meth)acrylate.
