NUSIL Technology Releases a Low Coefficient of Friction Silicone Coating

NuSil Technology LLC (http://www.nusil.com), a leading formulator and manufacturer of silicone compounds for the healthcare and pharmaceutical industries, announces the release of MED-6670, a curable coating that decreases the coefficient of friction of a cured silicone surface by a minimum of 50 percent when compared to a non-coated silicone surface.

NuSil designed MED-6670 to overcome obstacles in applications in which silicones come in contact with each other, such as precision molded parts, molded rubber stoppers or O-rings. Silicone elastomers inherently have a high degree of surface tack and a tendency for blocking (sticking to themselves by virtue of chemical affinity), which may cause problems in applications in which they come in contact with each other or other surfaces

MED-6670 is a two-part, low-coefficient of friction silicone coating dispersed in xylene. A thin coat of MED-6670 cures rapidly with elevated temperatures and once cured, the coating chemically bonds to the silicone elastomer substrate, mimicking its mechanical properties. The result is a smooth finish with durable, yet flexible coating that resists abrasion from moving, sliding and rubbing parts.

"By bonding to the substrate and resisting abrasion, the MED-6670 coating eliminates the concern of migration, which commonly associated with lubricants such as fluids or greases," said Brian Nash, vice president of sales and marketing. MED-6670 is designated unrestricted and safe for use in human implantation of 29 days or longer. Master Access File and biological testing are currently on file with the U.S. FDA. (the end)
