Silicone Coating Touts Low Coefficient of Friction

Sat, 06/05/2010 - 9:03am
NuSil Technology LLC announced the release of R-2182. This curable coating is designed to alleviate surface tackiness and blocking (sticking to themselves by virtue of chemical affinity) in applications in which silicones come in contact with each other or other surfaces, such as precision molded parts, molded rubber stoppers, O-rings, gaskets, accordions or cables/cable coatings. R-2182 can also be used to control the flow of hydrophilic fluids. According to the company, R-2182 decreases the coefficient of friction of a cured silicone surface by at least 50 percent as compared to a non-coated silicone surface, reduces the surface energy for masking by approximately 50 percent and has a high contact angle of 123°. This two-part, low-coefficient of friction silicone coating dispersed in xylene. A thin coat of R-2182 cures rapidly with elevated temperatures and, once cured, it chemically bonds to the silicone elastomer substrate, mimicking its mechanical properties.
