Cured perfluoroelastomer articles are disclosed which have improved surface characteristics. The articles are coated with a thin durable film comprising a fluorocarbon telomer which reduces surface stickiness, while maintaining the sealing properties of the article.

Perfluoroelastomer articles having good surface properties

Elastomeric parts having a magnetic flux density of at least 10 gauss on their surface deflect a portion of reactive plasmas from contact with the surface of the parts. Thus, such parts may be exposed to reactive plasmas for longer periods, with less degradation, than may similar elastomer parts that do not have such a magnetic flux density on their surface.

Plasma resistant elastomer parts

Cured perfluoroelastomer articles are disclosed which have improved surface characteristics. The articles are coated with a thin durable film comprising a polysiloxane and urethane oligomer which reduces surface stickiness, while maintaining the sealing properties of the article.
