Document Type and Number:
Japanese Patent JP2023057598
Kind Code:
A
Abstract:
To provide a composition to become a water absorption-preventive agent capable of giving excellent water absorption-preventive property onto the surface of a structural material.SOLUTION: An organoalkoxysilane-containing composition includes: (A) an organohydrogenpolysiloxane having a structural unit selected from the group consisting of SiO2, HSiO1.5, R1SiO1.5, R1HSiO, R12SiO, R12HSiO0.5, and R13SiO0.5; (B) an organopolysiloxane having a structural unit selected from the group consisting of SiO2, R2SiO1.5, R1SiO1.5, R1R2SiO, R12SiO, R13SiO0.5, and R12R2SiO0.5 (R2 is an alkenyl group); and (C) an organoalkoxysilane expressed by R3aSi(OR4)4-a and/or a partial hydrolysis condensation product thereof, where the content of (C) is 100-10,000 pts.mass to 100 pts.mass of a total of (A) and (B).SELECTED DRAWING: None
