Document Type and Number:
WIPO Patent Application WO/2024/080049
Kind Code:
A1
Abstract:
The present invention is an emulsion composition of a film-forming organopolysiloxane, the emulsion composition being characterized by comprising: 100 parts by mass of (A) an organopolysiloxane which is represented by average composition formula (1), has a viscosity of at least 300,000 mPa∙s at 25ºC, and contains alkoxy groups or hydroxy groups bonded to at least two silicon atoms in one molecule; 0.1-30 parts by mass of (B) a cationic surfactant; 30-3,000 parts by mass of (C) water; and 0.5-50 parts by mass of (D) colloidal silica. Consequently, provided is an emulsion composition of a film-forming organopolysiloxane having favorable film formability, excellent film strength and flexibility after curing, and favorable storage stability. (In the formula, R1 is a hydrogen atom or a C1-C20 monovalent organic group, and R2 is a C1-C20 alkyl group, a C6-C20 aryl group, a C1-C20 alkoxy group, or a hydroxy group.)
