Patent
Wacker Chemical Corporation | Date: 2015-09-28

Defoamer compositions contain a) a two-stage hydrosilylation product of one or more M_(4)^(H)Q or M_(3)^(H)T^(phenyl )starting materials with a hydrosilylatable composition containing -methylstyrene, and then with a linear or branched organopolysiloxane bearing at least two hydrosilylatable groups; b) a silicone resin; and c) silica. The defoamers are particularly useful in machine laundering and dishwashing compositions.

Water-in-oil invert emulsions containing no surfactant are formed by simple mixing of water with organopolysiloxanes containing all of aralkyl, long chain alkyl, and hydrophilic groups.

High electrolyte agrochemical formulations with reduced foaming are formulated with a polyorganosiloxane defoamer containing defoaming polyoxyalkylene ether groups and tertiary aminoalkyl groups. The defoamers are stable in the high electrolyte formulation.


Composite structures prepared by laying up a plurality of plies of thermoplastic or thermoset fiber reinforced prepregs are produced by adhering a high parting force consolidation liner on at least one surface of the layup prior to curing and consolidation. The surface coating on the release paper is preferably free of controlled release additives, adheres well to consolidated compositions, and can be removed to expose the composite surface.

Organopolysiloxanes bearing regularly spaced pendent carboxylic acid groups or salts thereof have a block polymer structure and are derived by the double half-esterification of a dianhydride and a silanol- or carbinol-functional organopolysiloxane or sulfur analog thereof. The products can form stable aqueous dispersions without the need for a surfactant.

A carpet product includes in sequence a) a primary backing material having a back side and a face side, with carpet fibers extending from the face side to form a carpet pile and also passing through the primary backing material and forming loops on the back side; b) a primary coating layer on the loops, including a vinyl acetate ethylene copolymer and present at from 542 to 1085 g/m^(2 )(16 to 32 oz./yd^(2)) on a dry solids basis; c) a secondary coating layer on the primary coating layer, including a styrene-butadiene copolymer; and d) a secondary backing material on the secondary coating layer and adhered thereby to the primary coating layer.

Stable emulsions of silicone terminated polyethers and silicone resins are used to prepare one-component grout with very good mechanical properties gained within a short time after the grout cures by adding a proportion of aggregate to the emulsions.


Patent
Wacker Chemical Corporation | Date: 2015-02-09

A grout compositions, storable with the exclusion of water, and crosslinkable upon ingress of water at room temperature is prepared by admixing a relatively minor proportion of a moisture-curable organopolysiloxanes, composition containing an alkoxysilyl-terminated, urethane-group-containing polymer and a silicone resin, with a major proportion of aggregate.


Patent

The subject of the invention is a polymer-modified asphalt composition obtained by blending asphalt with a vinyl acetate/ethylene polymer, and optionally with further additives, and a process for the preparation of the polymer-modified asphalt composition, and the use of the polymer-modified asphalt composition.


Patent
Wacker Chemical Corporation | Date: 2014-03-26

Aqueous emulsions of in situ-polymerized hydroxyl-functional organopolysiloxanes prepared in the presence of an acid catalyst and an alkanol have lower neat fluid viscosities than otherwise similar polymers prepared in the absence of the alkanol.
