WIPO Patent Application WO/2019/146523
Kind Code:
A1
Abstract:
The present invention relates to a coating agent composition including: (A) an organopolysiloxane resin which is solid at 25°C and which includes siloxane units represented by the general formula R1 3SiO1/2 and siloxane units represented by the formula SiO4/2, the mole ratio of siloxane units represented by the formula R3SiO1/2 to siloxane units represented by the formula SiO4/2 being 0.5-1.2; (B) an organopolysiloxane which is liquid at 25°C and which has at least two silicon-atom-bonded hydrolyzable groups or hydroxyl groups in each molecule thereof; (C) a silane compound or a partially hydrolyzed condensate thereof; (D) any condensation reaction catalyst; and (E) an organic solvent. This composition is capable of forming a thin cured coating film having minimal surface tack and excellent adhesion to a mortar, concrete, or other structure or to a primer layer or intermediate coat layer on the surface thereof.
