NuSil releases low friction silicone healthcare coating

ERJ staff report (RD)

Carpinteria, California -- NuSil Technology llc, a manufacturer of silicone compounds for the healthcare industry, has released a new 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 said 3 Feb.

MED-6670 was designed to cure quickly at elevated temperatures to reduce surface tack in obstacles where silicones come into contact with each other, such as precision moulded parts, moulded rubber stoppers or O-rings, the statement said.

Once cured, the two-part coating, which is dispersed in xylene, chemically bonds to the silicone elastomer substrate and mimicks its mechanical properties. The result, NuSil said, is a smooth finish with a durable, yet flexible coating that resists abrasion from moving, sliding and rubber 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 at NuSil.
