Abstract
Abstract An aqueous silicone emulsion coating material has been developed with can be used to form a membrane with a decorative, uneven surface. The decorative surface is durable and waterproof. The coating material consists essentially of aqueous silicone emulsion which gives an elastomer upon removal of the water component, inorganic filler, and short, hydrophilic, organic fibers.

An aqueous silicone emulsion coating material consisting essentially of (A) 100 parts by weight of aqueous silicone emulsion which gives an elastomer upon removal of the water component, (B) 10 to 200 parts by weight inorganic filler and (C) 0.1 to 10 parts by weight hydrophilic, organic fiber selected from the group consisting of natural fibers, regenerated fibers, and synthetic fibers, said fibers having a length of from 0.1 to 10 millimeters.
Claim 3
Dependent Claim
76 words
An aqueous silicone emulsion coating material described in claim 1, wherein the aqueous silicone emulsion which gives an elastomer upon removal of the water component consists essentially of (i) essentially linear organopolysiloxane having at least 2 silicon-bonded hydroxyl groups in each molecule, (ii) crosslinker for component (i), selected from the group consisting of colloidal silica, alkali metal silicate, hydrolyzable silane and the partial hydrolysis-condensation product of hydrolyzable silane, (iii) curing catalyst, (iv) emulsifier and (v) water.
Claim 4
Independent Claim
100 words
A method of forming a membrane with a decorative, uneven surface which is also durable and waterproof consisting essentially of (1) applying an aqueous silicone emulsion coating material consisting essentially of (A) 100 parts by weight of aqueous silicone emulsion which gives an elastomer upon removal of the water component, (B) 10 to 200 parts by weight inorganic filler and (C) 0.1 to 10 parts by weight hydrophilic, organic fiber selected from the group consisting of natural fibers, regenerated fibers, and synthetic fibers, said fibers having a length of from 0.1 to 10 millimeters, and (2) removing the water component.
