Abstract
The present invention is a composite coating material and a process for making the same. The composite material comprises a latex polymeric material into which has been dispersed high molecular weight polyethylene particles which have been surface treated under conditions to render the surfaces hydrophilic. The surface treated polyethylene particles are dispersed into the latex polymeric material in a concentration range of 1-50 wt. % of the total composite. When applied to a substrate, the resultant composite coating material exhibits high abrasion resistance and very low coefficients of friction after abrasive wear.
