Abstract

The objective of this work was to obtain polyurethane film that has antislip, mechanical and chemical resistance properties on ceramic tiles. For this aim, different 2K polyurethane compositions were studied by NCO:OH ratio ranging from 0.7 and 1.4. The compositions that NCO:OH ratio is greater than or equal to 1 can not be applied on ceramic tiles. Water resistance test, abrasion test, antislip test (DIN 51097 and 51130), UV resistance test, SEM/EDX analyses, stain resistance test (ISO 10545-14) were performed to other compositions. PU-3 composition was durable after keeping in water for 96 hours and 60000 cycles of abrasion test. According to antislip test, the coated surface by PU-3 composition was R10B. After UV resistance and stain resistance tests, the change in color of the surface was appropriate (ΔE<0.5). In SEM analysis it is seen that the granules used to obtain antislip properties were distributed randomly but homogeneously over the surface in PU-3. According to the test results, the PU-3 composition meets all desired values for high mechanical, chemical durability and anslip level according to the standards.
