Abstract:
The silicone emulsion composition for forming a rubber coating film according to the present invention, including
(A) an organopolysiloxane having at least two hydroxyl groups bonded to silicon atoms at terminal ends of the molecule in each molecule thereof,
(B) an aminoalkyltrialkoxysilane represented by formula (1) (where R1 through R3 represent H or a univalent hydrocarbon group, R4 and R5 represent divalent hydrocarbon groups, R6 represents a univalent hydrocarbon group, and n is an integer 0 to 6), (C) a vinyltrialkoxysilane represented by formula (2): CH2═CHSi(OR7)3 (where R7 represents a univalent hydrocarbon group), (D) a surfactant, and
(E) water
and not containing an organic tin compound, is free of problems with storage stability or byproducts, and a rubber coating film can be formed thereby in a short time without the use of an organic tin compound.
