Abstract:
Disclosed is a release material that can be applied as a liquid, gel, emulsion, foam, etc. in a shingle manufacturing line. The release material can also be used in the manufacturing of roll roofing. The release material primarily constitutes an emulsion of polymers that can be cured with heat, IR light or other methods. Silicone may also be included in the emulsion which assists in releasability. The release material can be sprayed or extruded on to the surface of the shingle in an automated fashion, eliminating the necessity for operator interaction.
