  • Method for preparing silicone rubber molds
    Patent number: 3989790
    Abstract: A silicone rubber mold is prepared by applying a room temperature curable, dough-like silicone composition to an area of a pattern which is vulnerable to high stress and thereafter the remainder of the pattern is coated with a flowable silicone composition which is curable at room temperature. The mold is cured and ultimately separated from the pattern being copied. The resulting silicone rubber molds may be used for high frequency flow molding.
