Abstract
Curable, solventless, liquid polyorganosiloxane compositions provide release coatings that exhibit a slippery feel. The composition comprises (a) a first polydiorganosiloxane terminated by silyl groups having one reactive group; (b) a second polydiorganosiloxane terminated by silyl groups having one reactive group, the reactive group of (a) being the same or different from the reactive group of (b), said reactive groups of (a) and (b) being reactive with one another to form a covalent bond; (c) a polydiorganosiloxane having three or more reactive groups that are reactive with either the reactive group of (a) or the reactive group of (b) or both to form a covalent bond; and (d) a catalyst for effecting the reaction of the reactive groups of (a), (b), and (c) to form covalent bonds. When coated on a substrate and cured, the composition provides release liners for pressure-sensitive adhesive tapes and pressure-sensitive adhesive transfer tapes.
