Title:
EMULSION COMPOSITION BASED ON ORGANOSILICON COMPOUND
Document Type and Number:
Japanese Patent JP3403217
Kind Code:
B2
Abstract:

PURPOSE: To obtain the subject composition which can improve the water repellency and storage stability of a porous inorganic base material by mixing a specified organoalkoxysilane, a specified organosiloxane, an anionic surfactant and water.
CONSTITUTION: 100 pts.wt. mixture of 100 pts.wt. organoalkoxysilane (A) of the formula R1aSi(OR2)4-a (wherein R1 is a 1-20C monovalent hydrocarbon group; R2 is a 1-3C monovalent hydrocarbon group; and a is 1 or 2) and 1-20 pts.wt. organosiloxane (B) having at least one organic group of the formula R3-Si(R4)b(OR2)3-6 (wherein R3 is a divalent hydrocarbon group; R is a monovalent hydrocarbon group; and (b) is 0 to 2) attached to an Si atom in the molecule is mixed with 0.1-50 pts.wt. anionic surfactant (C) and water (D) to form an emulsion so that the total content of components A and B is 5-60wt.%.
