Polymer coated contact surface
First Claim
1. A coated contact surface having a high coefficient of friction comprising a contact surface coated directly with a polymer having a hardness of 10 to 40 Shore A, a tensile strength of 400 to 1700 psi, an elongation of 200 to 1400 percent and a tear resistance of 50 to 400 PLI, wherein said polymer is a cross-linked acrylic polymer, a plasticized polyvinyl chloride elastomer, a silicone rubber, or a polyurethane elastomer, and forms a solid film from an evaporating solvent, said solidified polymer itself providing said high coefficient of friction.

Abstract
The gripping characteristics of the contact surface of a handle, grip or glove can be improved by applying an extremely soft, and/or tacky, elastomeric coating having a hardness of 10 to 40 Shore A, a tensile strength of 400 to 1700 psi, an elongation of 200 to 1400 percent and a tear resistance of 50 to 400 PLI, such as a cross linkable acrylic polymer. The coating solution can also contain a pigment. The thus formed coating solution is then applied to the contact surface and dried, so as to form the polymer coating.
