In the coating of rubber surfaces with adherent slip coatings the need for release agents is avoided by selecting as the slip coating a synthetic polymer latex composition consisting essentially of about 5 to 95% by weight of a film-forming, non-elastomeric synthetic polymer component (1) having an elongation of at least about 200% and about 5 to 95% of a normally solid, non-elastomeric, synthetic polymer component (2) exhibiting an elongation of below about 20% and a coefficient of friction of up to about 0.20, said slip coating having an elongation of at least about 200 up to 700%, a coefficient of friction of up to about 0.25 and a thickness of below about 0.005 inch.

Process for the production of rubber articles having improved slip

An article comprising a rubber surface provided with an adherent slip coating of a synthetic polymer latex composition consisting essentially of about 5 to 95% by weight of a film-forming, non-elastomeric synthetic polymer component (1) having an elongation of at least about 200% and about 5 to 95% of a normally solid, non-elastomeric, synthetic polymer component (2) exhibiting an elongation of below about 20% and a coefficient of friction of up to about 0.20, said slip coating having an elongation of at least about 200 up to 700%, a coefficient of friction of up to about 0.25 and a thickness of below about 0.005 inch.

Rubber articles having improved slip coatings

Rubber articles, such as surgeon's gloves, are provided with a synthetic resin slip coating by contacting the rubber surface with a synthetic resin latex composition. The slip coating is adherent to the rubber substrate and is very extensible without adverse effect. The synthetic resin slip coating includes from 5 to 90 percent by weight of a first resin copolymer component selected from the group consisting of vinyl chloride-alkyl acrylate copolymer, vinylidene chloride-alkyl acrylate copolymer, and vinyl acetate-alkyl acrylate copolymer, and correspondingly, from 95 to 10 percent by weight of a second resin copolymer component selected from the group consisting of vinyl chloride-vinyl ester copolymer, and vinylidene chloride-vinyl ester copolymer.
