  • Method of manufacture of silicone elastomer coated cloth
    Patent number: 4478895
    Abstract: A method of preparing a silicone elastomer coated cloth having a surface coating of silicone resin is described. The coated cloth is elastic and pliable with a surface which has superior dirt resistance. The cloth is first coated with an addition-reaction-curing silicone elastomer composition which uses a platinum system catalyst or with an organic peroxide-curing silicone elastomer composition. The uncured elastomer layer is then coated with a silicone resin composition of the addition-reaction-curing type which uses a platinum system catalyst and has a molar ratio of organic groups to silicon atoms of 0.8 to 1.8. The silicone elastomer composition layer and the silicone resin composition layer are then heat cured simultaneously.
