摘要： The gripping characteristics of the contact surface of a handle, grip or glove are improved by applying an extremely soft, elastomeric coating having a hardness of 20 to 40 Shore A, a tensile strength of 700 to 1700 psi, an elongation of 400 to 1400 percent and a tear resistance of 100 to 400 PLI, such as an oil-modified, styrene/ethylene-butylene/styrene block copolymers. The oil-modified, styrene/ethylene-butylene/styrene block copolymer is dissolved by high temperature, high shear mixing in an aromatic hydrocarbon solvent, such as ethyl benzene, in the range of 10% to 45% solids. 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.
