ABSTRACT:
The water-repellent silicone water-based emulsion composition of the present invention consists of a mixture of (A) a silicone water-based emulsion composed of water, emulsifying agent, and diorganopolysiloxane having at least 2 silicone-bonded hydroxyl groups in each molecule, (B) a silicone water-based emulsion composed of water, emulsifying agent, and organohydrogenpolysiloxane having at least 2 silicon-bonded hydrogen atoms in each molecule, and (C) curing catalyst. It is characterized by an excellent storage stability, and by the formation on curing of a rubbery elastomeric coating film which has an excellent alkali resistance, water repellency, water-repellant sealability, and durability of adhesion.
