Star Branched Silicone Polymers As Anti Mist Additives For Coating Applications

Abstract: A hydrido-silicone resin is incompletely reacted with an olefin under hydrosilation conditions to produce a partially substituted hydrido-silicone that is further reacted under hydrosilylation conditions with a vinyl containing silicone to consume the remaining hydride species to produce a composition that is useful as an anti-mist agent in the coating of flexible supports.

Specification

FORM 2 THE PATENT ACT 1970 (39 of 1970) & The Patents Rules, 2003 COMPLETE SPECIFICATION (See Section 10, and rule 13! 1. TITLE OF INVENTION STAR-BRANCHED SILICONE COATING APPLICATIONS POLYMERS AS ANTI-MIST ADDITIVES FOR 2. APPLICANT(S) a) Name b) Nationality c) Address GENERAL ELECTRIC COMPANY AMERICAN Company 1 RIVER ROAD, SCHENECTADY ,NY 12345 U.S.A. 3. PREAMBLE TO THE DESCRIPTION The following specification particularly describes the invention and the manner in which it is to be performed : - WO 2006/062714 PCT/US2005/041582 STAR-BRANCHED SILICONE POLYMERS AS ANTI -MIST ADDITIVES FOR COATING APPLICATIONS FIELD OF USE The present invention relates to coating flexible materials or supports such as sheets of paper or other polymeric material, either woven or non-woven, with a silicone composition. The present invention also relates to the coating of flexible materials or supports with liquid compositions comprising one or more cross-linkable polyorganosiloxanes wherein such polyorganosiloxanes are cross-linkable by an addition reaction, a condensation reaction, a cationic reaction, or a free-radical reaction. The present invention also relates to star branched polyorganosiloxanes (silicone polymers) that reduce misting during the application of the silicone composition (polyorganosiloxane) to the flexible material or support. The flexible support may be paper, cardboard, plastic film, metal film and the like. Some exemplary applications are paper for foodstuffs, adhesive labels, adhesive tapes, seals and the like. BACKGROUND OF THE INVENTION The coating of flexible supports with liquid silicones is typically carried out on coating devices that operate continuously at very high speed. These devices usually comprise coating heads composed of several rolls, including in particular a pressure roll and a coating roll that are continuously fed with a silicone composition that may or may not be cross-linkable, by means of a series of rolls that are placed next to one another. A strip of flexible support of the desired material to be coated is fed at high speed between the pressure roll and the coating roll to be coated on at least one of its surfaces. When it is intended to cross link the silicone coating, apparatus to implement a cross linking reaction are 1 WO 2006/062714 PCT/US2005/041582 positioned downstream of the coating head. The apparatus that implements cross linking may be for example an oven or an emitter of radiation, e.g. ultraviolet (UV) radiation or an emitter of a beam of electrons (EB). High speed coating of flexible supports with silicones has been associated with problems associated with the transfer of the silicone liquid (or fluid) from the coating roll to the flexible support which moves forward through the coating apparatus. One of the particular problems associated with transfer of the silicone liquid from the coating roll to the flexible support is the appearance of a fog, mist or aerosol in the immediate vicinity of the coating head and particularly close to the points of contact between the coating roll and the flexible support being coated. Typically, the density of this fog, mist or aerosol increases with an increase in the forward speed of the flexible support being coated by the apparatus. The first effect of this transfer problem is to reduce the amount of silicone liquid actually transferred to the flexible support. A second effect is for the droplets comprising the fog, mist or aerosol to condense onto the newly coated flexible support downstream of the coating rolls creating an orange peel effect. This orange peel effect, or coating non-uniformity, creates problems with coverage, the mechanical properties of the coating, e.g. ruboff, and adhesion resistance. An additional problem caused by non-uniformity in the coating is related to industrial hygiene and the safety of people operating the coating equipment who are working in the vicinity of the coating equipment. SUMMARY OF THE INVENTION The present invention provides fpr a composition comprising the reaction product of: 2 WO 2006/062714 PCT/US2005/041582 in the presence of a noble metal hydrosilylation catalyst where the subscripts a, b, c , d , e , f , g, h, i, j, k, 1, m, n, o, p, are zero or positive and q is non-zero and positive, for mixtures of compounds the average values of each of the subscripts will most likely be non-integral, for specific compounds the subscripts will be integral, with k + m+o-g-h-I
