<p>A method of decreasing wear on flexible bodies caused by rubbing on rigid surfaces is shown. The rigid surface is coated with a paraffin composition, preferably paraffin or petroleum wax. Improved stability of the composition, with time, is obtained by incorporating, in the composition, an additive such as polyethylene. The compositions are applied to rigid surfaces such as concrete by spraying or by roller application. In the former case the compressed air for the spray gun and the surface to be coated are heated. The coatings may be advantageously applied to concrete tracks upon which air cushion (hover) vehicles are guided.</p> |
