Abstract
An oil-in-water type silicone emulsion composition is provided that can be uniformly coated onto a substrate and can, upon removing water content, form a cured film with low surface tackiness and excellent adhesive properties to a substrate and film strength. The oil in water type silicone emulsion composition comprises: (A) 100 parts by mass of polyorganosiloxane having at least two hydroxyl groups or hydrolyzable groups bonded to a silicon atom in one molecule, where the viscosity at 25° C. is within a range of 100,000 mPa-s to 20,000,000 mPa-s; (B) 45 to 120 parts by mass of colloidal silica (based on solid fraction); (C1) 1 to 100 parts by mass of an ionic emulsifier; and (D) 0 to 500 parts by mass of water (excluding water content in component (B), if any). Optionally, the composition further comprises (C2) a polyoxyethylene-polyoxypropylene copolymerized nonionic emulsifier. The composition can be used as a surface treating agent.
