What is so special about synthetic rubber conformal coatings? Why do many high reliability applications require synthetic rubber? Would synthetic rubber be a better fit for your application? Synthetic rubber copolymer provides higher operating temperature and exhibits superior mechanical properties compared to traditional materials. The products have been developed to withstand the demanding conditions in the most severe environments required in today’s applications. Commonly used conformal coatings are acrylic, polyurethane and silicone. Less known are synthetic rubber conformal coatings, however these have been used for many years and HumiSeal continues to develop new and improved varieties of this chemistry.
