20090294023 | Pressure sensitive adhesives and methods for their preparation - A pressure sensitive adhesive composition includes (A) a bodied MQ resin containing (i) a resinous core and (ii) a nonresinous polyorganosiloxane group, where the nonresinous polyorganosiloxane group is terminated with a silicon-bonded hydroxyl group; (B) a treated MQ resin, where (B)/(A) ratio has a value of 0.3 to 5.0, and (C) a polydiorganosiloxane terminated with a condensation reactable group; where resin/polymer ratio has a value of 2.0 to 3.0; optionally (D) a crosslinker; optionally (E) a catalyst; and optionally (F) a solvent. A pressure sensitive adhesive product prepared by curing the pressure sensitive adhesive composition is useful in structural attachment applications such as structural glazing applications. | 12-03-2009 |
20100093902 | Blocked-Isocyanate Silicone Resins - This invention relates to new blocked isocyanate silicone resins which can be used to make shelf stable one part curable coating compositions. These coatings do not cure until heated. The coatings provide weather resistant protection for numerous substrates including automobile exteriors, leather fabric, electronic components, wood floors and surfaces. | 04-15-2010 |
20100272673 | Ionomeric Silicone Thermoplastic Elastomers - This invention relates to thermoplastic elastomers comprising at least one silicone ionomer. These thermoplastic elastomers may be reprocessed and/or recycled. | 10-28-2010 |
20100317249 | Article Comprising Fibers And A Method Of Forming The Same - An article is provided that comprises fibers, as is a method of forming the article. The fibers comprise an organopolysiloxane component selected from (i) an organopolysiloxane having the formula (R3SiOi/2)w(R2Siθ2/2)x(RSiθ3/2)y(Siθ4/2)z (I), wherein each R is selected from the group of an inorganic group, an organic group, and combinations thereof, w is from 0 to 0.95, x is from 0 to 0.95, y is from 0 to 1, z is from 0 to 0.9, and w+x+y+z=1, and (ii) a cured product of said organopolysiloxane having the formula (I), and combinations of (i) and (ii), provided that the fibers are free from organic polymers, organic copolymers, and organosiloxane-organic copolymers. The method of forming the article includes the step of forming fibers from a composition. The composition used to form the fibers comprises the organopolysiloxane having the formula (I), provided that the composition is free from organic polymers, all-organic copolymers, and organosiloxane-organic copolymers. The article exhibits excellent hydrophobicity and maximized fire resistance. | 12-16-2010 |
20110046272 | FILLED RUBBER COMPOSITIONS - The present invention relates to a curable rubber composition comprising an organic elastomer, a filler and at least one curing agent for the elastomer. Such curable rubber compositions are widely used in the production of cured rubber articles, such as tyres, belts and hoses. The composition contains a branched silicone resin having Si-bonded hydroxyl groups or azo groups. This may lead to a reduction in the mixing energy required for processing, particularly in the energy required in the first (non-productive) mixing phase to give good dispersion of the filler in the organic elastomer. Use of the branched silicone resin can also accelerate cure (vulcanization), thus reducing the required cure time or reducing the amount of cure accelerator required. | 02-24-2011 |
20110110873 | Personal Care Compositions Having Improved Compatibility and Providing Improved Sun Protection - Personal care composition having improved compatibility and providing improved sun protection are obtained by including a liquid silicone resin having greater than 50 mole percent Me | 05-12-2011 |
20120251729 | Coating Compositions With Alkoxy-Containing Aminofunctional Silicone Resins - This invention relates to a coating composition comprising (A) 100 weight parts of at least one epoxy resin; (B) 40 to 900 weight parts of at least one alkoxy-containing aminofunctional silicone resin; (C) up to 50 weight parts of at least one organic hardener; (D) up to 100 weight parts of at least one epoxyfunctional silicone resin; and (E) up to 10 weight parts of at least one cure accelerator, provided the alkoxy-containing aminofunctional silicone resin (B) has a total alkoxy content ranging from 26 to 80 mol percent per mole of silicon (Si) in the alkoxy-containing aminofunctional silicone resin.
