SILANE COUPLING AGENT
Document Type and Number:
WIPO Patent Application WO/2022/039043
Kind Code:
A1
Abstract:
Provided is a silane coupling agent having low viscosity and excellent coatability, and having an excellent effect of improving the adhesiveness between inorganic materials and organic materials. This silane coupling agent contains a silicon compound described below and water, the silicon compound concentration being 0.01-10 wt%. Silicon compound: contains a compound (I) represented by formula (1) and a polycondensate thereof, the ratio (compound (I)/compound (II); ratio by weight) of the amount of compound (I) and the amount of a compound (II), which is the portion of the polycondensate of compound (I) having a weight-average molecular weight expressed in terms of standard polystyrene of 200-10000, being 1/99-95/5
