Abstract

A process for producing a flexible hardened finish on a rubber surface comprises superficially treating the surface with concentrated sulphuric acid alone or with a diluent, the concentrated acid being the major ingredient. The acid may have a concentration of 66 DEG B<\>ae. The diluent may be water, up to 25 per cent (by volume), or water-soluble organic liquids such as methyl, ethyl or isopropyl alcohol and polyhydric alcohols such as glycerol or ethylene glycol. Suitable mixtures are 20 parts of glycerol or ethylene glycol or 15 parts of glycerol &c. and 5 parts of water with 80 parts (by volume) of 66 DEG B<\>ae acid. The rubber article should not contain more than 3 parts of combined sulphur per 100 parts of rubber. The time of treatment is a few seconds up to 2 minutes.
