Abstract: A crosslinkable composition is useful for preparing a skin contact adhesive or a coating on a substrate. The crosslinkable composition includes (A) a polyurethane-polyorganosiloxane copolymer and (B) a curing catalyst. The skin contact adhesive prepared by crosslinking the crosslinkable composition is useful in applications such as adhesives for medical tapes, adhesives for wound dressings, adhesives for prosthetics, ostomy appliance adhesives, adhesives for medical monitoring appliances, adhesives for scar therapy treatments, adhesives for cosmetic patches, and transdermal drug delivery systems.

Abstract: The invention relates to coatings for leather. In particular it relates to top coats for leather. It provides a leather coating composition comprising an organic synthetic resin in aqueous dispersion and an organopolysiloxane, characterized in that the organopolysiloxane is present in aqueous emulsion and comprises a silicone resin having an empirical formula: (I) where •R is a monovalent organic group having 1-30 carbon atoms, •Z is hydrogen or an alkyl group having 1-4 carbon atoms, •x has a value from 0.75 to 1.7, and •y has a value from 0.1 to 2.0, and having a viscosity of from 1 to 4000 mPa·s at 25° C. We have found that the use of a silicone resin according to the invention greatly increases the abrasion resistance, as measured by the Taber method, of leather coated with the coating composition.
