摘要:
The invention relates to transparent varnish used in industries such as parquet, wooden furniture, paper, plastic and the like and not including any volatile organic material and the production method thereof. The method realized in order to achieve the objects of this invention mainly comprises the following steps: using an UV-curable polymer or oligomer resin without any volatile organic material within the reactor, making the reaction medium acidic, adding nano-sized metal oxide particles to the mixture, adding silanes to the system, modifying the surfaces of metal oxides with the structure obtained, removing the alcohol and water formed during the reaction, leaving the gel formed for the completion of the reaction, thinning the gel with a reactive thinner after the completion of the reaction, curing the final product in UV oven by adding photo-initiator.

The invention further relates to an activation treatment for an organic coating to enhance adhesion of the coating to a further coating and/or to other entities comprising a solvent and a surface chemistry and/or surface topography modifying agent and a method for the preparation of the activation treatment.
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 conjugated molecular assembly includes a substrate (100) and an extended conjugated molecule (120) attached to the substrate, the extended conjugated molecule (120) including a first conjugated molecule (130) having a first functional group (G1) for attaching to the substrate (100), and a second conjugated molecule (140) which is covalently linked to the first conjugated molecule.
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.
