Abstract
A glass fiber product for laminates is provided having excellent epoxy resin impregnation properties and solvent resistance, high soldering heat resistance, good heat shock resistance and low water adsorption properties, and to a silane coupling agent for providing such a glass fiber product. The silane coupling agent is prepared by reacting 2.3 to 4.0 mols of a haloalkylalkoxysilane with 1 mol of a diamine having N atoms to which 4 active hydrogen atoms are bound, a silane coupling agent prepared by reacting 1.3 to 3.0 mols of a haloalkylalkoxysilane with 1 mol of a diamine having N atoms to which 3 active hydrogen atoms are bound and to which one alkylsilyl group is bound, or a silane coupling agent prepared by reacting 0.3 to 2.0 mols of a haloalkylalkoxysilane with 1 mol of a diamine having N atoms to which 2 active hydrogen atoms are bound and to which 2 alkylsilyl groups are bound. A silane coupling agent prepared by reacting the diamine with a haloalkylalkoxysilane and a halomethylstyrene is also provided as is a glass fiber product for laminates treated with the above-mentioned silane coupling agent.
