Abstract
A coating on a substrate which endows the substrate with a desired surface property, the coating comprising a cross-linked polysiloxane containing X'-- and X-groups attached to different Si atoms wherein the groups X'-- are monovalent organic groups which provide the desired surface property and the groups X-- are monovalent organic groups which are reactive with a group on the substrate surface and have a higher surface tension than the groups X'--, said coating being bonded to said substrate by reaction of X-groups with substrate surface groups reactive therewith. In one embodiment a non-wetting coating is provided wherein the X'-- group has the formula CF.sub.3 Z-- where Z is a divalent organic group or the formula CH.sub.3 (CH.sub.2).sub.t where t is at least 3.
