  • Siloxane graft co-polymers for mold release
    Patent number: 9309412
    Abstract: A graft co-polymer is provided comprising a vinyl polymeric backbone with grafts of siloxane monomers and monomers containing an anchoring group. Such co-polymers are well suited for coating metal molds. The siloxane groups provide release to the metal mold, while the anchoring groups provide durability to the coating. The durability and release characteristics may be varied by the number of grafts of each monomer and the molecular weight of the siloxane moiety. The co-polymers may be coated from water or organic solvents.
    Type: Grant
