Abstract
Organosiloxane compositions comprising specified combinations of MQ resins and liquid polyorganosiloxanes can be applied as molten materials to form coatings that are non-flowable under ambient conditions and can initially be remelted by heating the coating above its flow transition temperature. In the presence of moisture, the flow transition temperature of the coating gradually increases due to the reaction of hydrolyzable groups on the polyorganosiloxane ingredient until the coating is converted to a non-flowable resin reinforced elastomer. Preferred coatings are non-transferable at 25.degree. C. within ten minutes following application.
