The GESTER GT-KC01-2 IULTCS & Veslic Tester is a high-efficiency laboratory testing instrument engineered to assess the rubbing color fastness and surface durability of natural leather, synthetic leather, plastics, and coated textiles. Featuring two independent testing stations, the iultcs veslic rub fastness tester allows laboratory technicians to perform simultaneous dry and wet rubbing fastness tests or run parallel sample evaluations, effectively doubling testing throughput. Fully compliant with ISO 11640, SATRA PM 173, and EN ISO 20344, the instrument evaluates finish adhesion, color bleeding, and surface degradation under controlled cyclic pressure using standard white wool felt pads. It is widely used in commercial testing laboratories, tannery R&D centers, footwear manufacturing facilities, and automotive trim production lines.
