1. An article of manufacture comprising a first component having a surface in frictional engagement with a surface of a second component, at least a portion of at least one surface of at least one of the first component or the second component being coated with a coating prepared from a composition comprising:
(a) a first, curable organopolysiloxane comprising at least two alkenyl groups, wherein the first organopolysiloxane (a) is (7.0-8.0% vinylmethylsiloxane)- dimethylsiloxane copolymer, trimethylsiloxy terminated,
and
(b) a second, curable organopolysiloxane comprising at least two polar groups, the second organopolysiloxane being different from the first organopolysiloxane, each polar group of the second organopolysiloxane (b) being independently selected from the group consisting of acrylate, methacrylate, amino, imino, hydroxy, epoxy, ester, alkyloxy, isocyanate, phenolic, polyurethane oligomeric, polyamide oligomeric, polyester oligomeric, polyether oligomeric, polyol, and carboxypropyl, and fluoro groups.
2. An article of manufacture comprising a first component having a surface in frictional engagement with a surface of a second component, at least one surface of at least one of the first component or the second component being coated with a coating prepared from a composition comprising:
(a) a first, curable organopolysiloxane comprising at least two alkenyl groups, and
(b) a second, curable organopolysiloxane, wherein the second organopolysiloxane (b) is 15-20% (acryloxypropyl)methylsiloxane – dimethylsiloxane copolymer.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
