Claims
- 1. In a process for the production of rubber articles having a slip coating on at least one surface thereof, wherein a form is first coated with a release agent, a slip coating composition is provided on said release agent coated form and a rubber substrate is thereafter formed over said slip coating, the improvement which comprises eliminating the need for said coating of release agents by selecting as said slip coating eomposition a mixture of polymeric resins 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 95 to 5% by weight 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.
- 2. The process of claim 1 wherein said rubber article is a sheet-like rubber article.
- 3. The process of claim 1 wherein said sheet-like rubber article comprises a rubber glove.
- 4. The process of claim 3 wherein said rubber glove is a sterile material rubber surgeons' glove.
- 5. The process of claim 4 wherein both the inside surface and outside surface of said glove are provided with a 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.
- 6. The process of claim 1 wherein the form is a bisque ceramic form.
- 7. The process of claim 6 wherein the bisque ceramic form is a bisque porcelain form.
