Abstract
An aqueous silicone dispersion capable of forming an elastomer coating film when dried at a normal temperature, said aqueous silicone dispersion comprising: (A) a silicone elastomer which is an addition reaction product of an alkenyl group-containing organopolysiloxane (A-1) having 2 or more alkenyl groups per molecule, an organopolysiloxane (A-2) having 3 or more hydrosilyl groups per molecule and a linear diorganopolysiloxane (A-3) having hydrosilyl groups at both ends of the molecular chain; (B) an anionic surfactant; (C) a nonionic surfactant; (D) colloidal silica; and (E) water.
Claims8
An aqueous silicone dispersion comprising:
- (A) a silicone elastomer which is the addition reaction product of (A-1) an alkenyl-containing organopolysiloxane having at least 2 alkenyl groups per molecule with (A-2) an organohydrogenpolysiloxane having at least 3 hydrosilyl groups per molecule and (A-3) a linear diorganohydrogenpolysiloxane having hydrosilyl groups at both ends of the molecular chain,
- (B) an anionic surfactant in an amount of 0.1 to 5 parts by weight per 100 parts by weight of component (A),
- (C) a nonionic surfactant in an amount of 0 to 2 parts by weight per 100 parts by weight of component (A),
- (D) colloidal silica in an amount of 0 to 35 parts by weight per 100 parts by weight of component (A), and
- (E) water in an amount of 15 to 200 parts by weight per 100 parts by weight of components (A) and (D) combined,
- the dispersion having the silicone elastomer (A) dispersed therein and being capable of forming an elastomer film upon drying at normal temperature.
