Abstract
Anti-blocking compositions are disclosed that include a wax or mixture of waxes effective to reduce, retard or prevent blocking of a viscoelastic solid when applied to the surface of such a solid. Also disclosed are methods of reducing, retarding or preventing blocking of a viscoelastic solid, and the products of those methods which are viscoelastic solids resistant to blocking.
Claims14
An anti-blocking composition comprising:
- at least one wax comprising a water-based emulsion formed from a mixture of a homopolymer selected from a polyethylene homopolymer and an oxidized polyethylene homopolymer;
- and a copolymer selected from an ethylene acrylic acid copolymer and an ethylene-vinyl acetate copolymer;
- wherein said at least one wax is utilized in an amount effective to reduce blocking of a viscoelastic solid when said composition is applied to the surface of said viscoelastic solid.
A method of reducing blocking of a viscoelastic solid, comprising the steps of:
- a) treating the surface of a viscoelastic solid after manufacture with an anti-blocking composition comprising a water-based emulsion formed from a mixture of a homopolymer selected from a polyethylene homopolymer and an oxidized polyethylene homopolymer;
- and a copolymer selected from an ethylene acrylic acid copolymer and an ethylene-vinyl acetate copolymer;
- and
- b) drying;
- thereby providing a viscoelastic solid coated with said anti-blocking composition components.
