Abstract
The invention disclosed herein relates to an elastomeric article, such as a glove, containing an elastomeric material such as latex and a coating layer formed from an aqueous dispersion containing a composite of a silicone-modified polymer, e.g., a silicone-modified polyurethane, and silicone resin particles integrated therein. The interaction between the silicone groups on both the polymer and particles produces enhances binding effectiveness of the particles to the material. Gloves and other articles made in accordance with the invention contain a microroughened skin-contacting surface and exhibit a reduced coefficient of friction and increased lubricity, thereby enhancing the donning properties thereof.
Claims39
An elastomeric article having an elastomeric material and a coating layer adhered to said elastomeric material, which coating layer comprises:
- a) a silicone-functionalized polymer;
- and
- b) silicone particles integrated throughout said polymer;
- wherein the coating layer is on a contacting surface of the article and there is a chemical affinity between the silicone functional groups on both the polymer and the silicone particles.
An aqueous dispersion for coating elastomeric materials to increase lubricity comprising:
- a) a silicone-functionalized polymer;
- and
- b) silicone particles;
- wherein there is a chemical affinity between the silicone functional groups on both the polymer and the silicone particles.
A method of making an elastomeric article comprising the steps of:
- a) forming a first layer of elastomeric material;
- and
- b) adhering a second, friction-reducing coating layer to the first layer, said coating layer being formed from a dispersion comprising a silicone-functionalized polymer in combination with silicone particles integrated therein, wherein there is a chemical affinity between the silicone functional groups on both the polymer and the silicone particles.
A method of making a powder-free glove comprising the steps of:
- a) forming a first layer of elastomeric material;
- b) adhering a second, friction-reducing coating layer to said first layer, said coating layer being formed from a dispersion containing a silicone-functionalized polymer in combination with silicone particles integrated therein wherein there is a chemical affinity between the silicone functional groups on both the polymer and the silicone particles;
- and
- c) subjecting the coated glove to a chlorination process.
