Abstract
A process for coating a front and back surface of an industrial textile to increase its abrasion resistance is disclosed. The coating process comprises the steps of coating the textile with a coating compound, heating coated textile at a temperature of 120 degree Celsius and drying the coated textile for 60 seconds. Two passes of coating is applied for the process wherein the viscosity for first pass of coating is 21000 centipoise and the viscosity for second pass of coating is 12000 centipoise. On completion of the coating process, the coated textile is treated with a water repellent agent. The coating compounds used for the process are comprised of formulations including two polyurethane compositions, which are mixed with a methyl ethyl ketone solvent, and the water repellent agent is silicone. The overall process requires a curing time of 2 minutes with a curing agent.
