NuSil launches low friction silicone rubber coating

ERJ staff report (LMH)

Carpinteria, California -- NuSil Technology llc, has developed a low-friction silicone coating for rubber parts such as O-rings, gaskets and moulded stoppers.

NuSil, which formulates and manufactures silicone compounds for engineering industries, announced the release of R-1182, a one-part, acetoxy-cured, low-coefficient-of-friction silicone coating in a 15 Sept news release.

R-1182 is dispersed in tert-butyl acetate, a non-volatile, organic component solvent, according to the news release. NuSil said the smooth coating is curable at room temperature and, once cured, chemically bonds to the silicone elastomer substrate, mimicking its mechanical properties.

R-1182 decreases the coefficient of friction of a cured silicone surface by an average of 85 percent as compared to a non-coated silicone surface, NuSil of Carpinteria, California, said.

“In a cured state, silicone has a naturally tacky surface that tends to pick up dust, dirt and grime,” commented Brian Burkitt, product director - engineering materials. “For ease of cleaning, R-1182 can be applied to prevent the accumulation of Foreign Object Debris (FOD).”
