    摘要: The invention concerns a method for producing an assembly comprising several silicone elements crosslinked by polyaddition of Si-H units on Si-alkenyl (preferably Si-vinyl) units, said elements adhering firmly to each other, without deteriorating the mechanical properties of the crosslinked silicone elements. Said method essentially comprises the following steps: (I) forming (first coating) a silicone element (i) using a liquid silicone preparation (i) comprising polyorganosiloxanes (POS) (A)- with Si-vinyl units, POS (B) with Si-H units, a platinum catalyst (C), optionally a POS Si-vinyl resin (D), optionally a crosslinkage inhibitor (E), optionally an adherence promoter (F), optionally a mineral filler (G), optionally a functional additive (H) for providing specific properties; (II) crosslinking such that (i) has an unreacted surface vinyl-residue density (DS) per nm : 0.0100 >/= DS >/= 0.0400; (III) optionally repeating steps (I) and (II) n times (n being a positive integer), so as to obtain n mutually adhering elements (i); (IV) forming (second coating) a silicone element (ii) with a silicone liquid preparation (ii) of the same type as described above; (V) crosslinking to obtain crosslinked (ii) adhering to (i). The invention is useful for producing multilayer silicone coatings.

    摘要: A permanent, roughened or textured surface is applied to parts molded from polyolefins, particularly from polyethylene by applying to the surface of the part a coating mixture of a tackifier resin and polyolefin particles in a liquid carrier and incorporating a granular or particulate matter in the coating, either by application to the coating or by admixing the granular or particulate matter into the coating mixture. The coated surface is heated to the melt temperature of the polyolefin for a short time, sufficient to gel the polyolefin particles of the coating into the surface of the part, but insufficient to cause any thermal distortion of the part.
