WebApr 13, 2024 · Silane Terminated Polymers: A Safer Solution. Our innovative chemists have taken a very good polymer design and eliminated the nasty NCO group, by adding a silane molecule, which in a sealant crosslinks by a reaction of a silanol Si-OH, to form a Si-O-Si bond. This is most easily done with an isocyanato silane, which is shown below. WebThe range is widely used for synthetics, fabric coatings and printing on fabric. In addition, our Platilon® and Dureflex® TPU films are well established in the sports apparel industry. Applied in thin layers, PU coatings add breathability and water resistance to outdoor gear, as well as high-performance seals for seams and enhanced fabric colors.

The criteria of all three of these tests must be met for the PU material to get a passing grade. It is important to understand the differences in the two tests. The ISO test is the more widely known test. proshop bells
