Patent number: 4857582Abstract: Colloidal suspensions of organopolysiloxanes are prepared by mixing an organosilicon compound selected from the group consisting of mixtures of alkoxysilanes and/or partial hydrolysates thereof and an organo(poly)siloxane which is optionally free of alkoxy groups and contains a maximum of 8 siloxane units, which is mixed with at least one alkoxysilane and/or a partial hydrolysate thereof, with water in the presence of an emulsifier, at a maximum rate of 5 moles of organosilicon compound per hour per liter of water, in which the organosilicon compound and the water is fed continuously, but separately from one another, into a reactor, in which at least one of the two substances contains an emulsifier, while the alkanol is being continuously removed by distillation from the aqueous suspension continuously emerging from the reactor. The aqueous suspension from which the alkanol has been removed by distillation is, if desired, recycled back into the reactor.Type: GrantFiled: May 18, 1988Date of Patent: August 15, 1989Assignee: Wacker-Chemie GmbHInventors: Matthias Wolfgruber, Bernward Deubzer, Volker Frey

Patent number: 4855352Abstract: Stable finely-divided dispersions of polyureas and/or polyhydrazodicarbonamides in a hydroxyl-group-containing material are made by reacting (i) an isocyanate with (ii) a compound selected from polyamines, hydrazines, hydrazides and mixtures thereof in the presence of (iii) a hydroxyl compound selected from polyethers, polyesters, polyester amides, polycarbonates and mixtures thereof and (iv) a catalyst. The catalyst is a compound which catalyzes the reaction of isocyanate groups with hydroxyl groups. The catalyst is used in a quantity of at least 50 parts per million parts of (i), (ii) and (iii). These dispersions are particularly useful in the production of polyurethanes.Type: GrantFiled: July 28, 1988Date of Patent: August 8, 1989Assignee: Mobay CorporationInventors: Michael K. Lowery, Richard E. Keegan, Mark A. Koshute

Patent number: 4800040Abstract: There are provided low temperature, storage stable, liquid mixtures of (1) isocyanato-containing prepolymers obtained from the reaction of linear and/or slightly branched polyols and a polyisocyanate characterized by a methylene group --CH.sub.2 -- bonded to two benzenoid nuclei, and (2) a non-hydroxyl-containing flow modifier which is compatible with the said prepolymer. Novel liquid mixtures thus prepared exhibit little tendency to crystallize or phase separate when stored for prolonged periods of time, i.e., well below room temperature for several days.Type: GrantFiled: May 20, 1987Date of Patent: January 24, 1989Inventor: Fritz Hostettler

Patent number: 4778845Abstract: A one-component adhesive and/or sealing mass which is stable and pumpable at temperatures up to 30.degree. C. containsat least one prepolymer on the basis of a polyurethane, which contains from 0.1 to 15 percent by weight, referred to the prepolymer, of free, reactive isocyanate groups, andat least one with heat activatable hardener.Thereby the stoichiometric ratio between said prepolymer and said hardener is chosen in such a way that only a partial cross-linkage is possible during heating said mass to temperatures from 60.degree. C. to 180.degree. C., and that a product is obtained having from high viscous to plastic characteristics.The inventive masses may be used for bonding and/or sealing of one or more materials of the same or different origin to a composite.Type: GrantFiled: June 4, 1987Date of Patent: October 18, 1988Assignee: Sika AG, vorm.
