Abstract
A composition for promoting the release of bituminous materials and other adhesive materials from a substrate and methods of use thereof. More particularly, a composition comprising a silicone oil-in-water emulsion, which is stabilized by an alkoxylated polysiloxane surfactant, for use as a release agent that can be applied to a substrate, such as a truck bed, prior to use for promoting the free release of a bituminous material, such as asphalt, from the substrate.
Claims20
A method for promoting the release of an organic material from a substrate, the method comprising:
- (a) providing a substrate;
- (b) applying a release composition to the substrate before contacting the substrate with the organic material, wherein the release composition comprises:
- (i) a silicone oil component;
- and
- (ii) an alkoxylated polysiloxane surfactant;
- and
- (c) contacting the substrate with the organic material.
A method for releasing asphalt from a substrate, the method comprising:
- (a) applying a release composition to a substrate to form a coated substrate, wherein said release composition comprises:
- (i) a silicone oil component, and (ii) an alkoxylated polysiloxane surfactant;
- (b) contacting the coated substrate with hot asphalt;
- and
- (c) removing the asphalt from the substrate.
A method for promoting the release of an organic material from a substrate, the method comprising:
