Abstract: A release coating composition includes a curable polysiloxane and an aerosol suppressant that has more than one SiO4/2 unit. The aerosol suppressant includes the polymerization product of a siloxane and a cyclic polysiloxane polymerized in the presence of a polymerization catalyst. The siloxane has units of the chemical formula (SiO4/2)(RaRb2SiO1/2)x wherein Ra is a vinyl moiety, Rb is an alkyl moiety, and x is a number from 1.05 to 4. The release coating composition is formed by combining the aerosol suppressant and a curable polysiloxane. The release coating composition is also used to coat a substrate in a release coating process producing a mist of less than 50 mg/cubic meter measured at approximately 457 m/min.

Abstract: The present invention relates to silicone compositions that can be used to control the interface at which release occurs when a bi-layer or multi-layer structure comprising compositions as separate layers, and a pattern of a different material sandwiched in between, is separated. The present invention further relates to a process that utilizes these compositions to control the transfer or release of patterns deposited on a substrate.

Abstract: A release coating composition according to the present invention comprises an alkenyl functional polysiloxane (1), a silicon hydride functional polysiloxane (11) and a catalyst (111) comprising a platinum group metal. The alkenyl functional polysiloxane (1) is an alkenylterminated polysiloxane prepared by siloxane polycondensation and/or equilibration using a phosphazene base catalyst followed by neutralisation with an acidic neutralising agent. The level of catalyst (III) in the composition can be as low as 2-40 parts per million platinum group metal by weight.

Abstract: The present invention relates to curable silicone coatings containing silicone resins. More particularly the present invention relates to curable silicone coating compositions comprising an olefinic organopolysiloxane, an organohydrogensiloxane, a platinum catalyst, and silicone resins in which the resins are prepared by a continuous method whereby the ratio of reactants is kept constant thus producing less variation in the final silicone resin that is produced. The silicone resins provide beneficial release properties when added to curable silicone coating compositions.

Abstract: The present invention relates to methods for making silicone resins. More particularly, the present invention relates to methods for producing silicone resins comprising monofunctional units in the form of R.sub.3 SiO.sub.1/2 units and tetrafunctional units in the form of SiO.sub.4/2 units. The methods of the present invention are characterized by a continuous process for producing silicone resins while maintaining a constant ratio of reactants thus producing less variation in the final product. The present invention is further related to the compositions produced by the methods of this invention.

Abstract: The use of siloxanes for conditioning of hair is disclosed. They hold particular usefulness as substitutes for oxidizing agents in the hair waving process. A novel polymeric composition which comprises a silanol endblocked polydiorganosiloxane, cyclic siloxanes, a chlorobenzyl-functional siloxane and a catalyst is also disclosed.

Abstract: There is disclosed a herbicide composition in which a postemergent herbicide is activated by the inclusion of a silicone glycol adjuvant consisting essentially of (i) a silicone glycol having an average of 4 or 5 ethylene oxide units in its glycol chain and (ii) a silicone glycol dispersant compound for component (i). The composition provides enhanced phytotoxicity in the control of weeds, particularly velvetleaf plants, and shows an improved degree of rainfastness relative to prior art compositions.

Abstract: There is disclosed a herbicidal composition in which a foliar-applied herbicide is activated by the inclusion of a silicone glycol-silicone alkane terpolymer adjuvant. The composition provides enhanced phytotoxicity in the control of narrowleaf weeds, particularly Barnyardgrass, Quackgrass and Johnsongrass, and often also shows an improved degree of rainfastness relative to similar herbicidal compositions employing prior art silicone glycol adjuvants.
