Abstract:
A process for producing a low VOC epoxy silane oligomer which includes hydrolyzing an epoxy silane, the epoxy silane upon hydrolysis of its hydrolyzable sites producing a reduced amount of volatile organic compound compared to that produced by the hydrolysis of a silane possessing an equivalent number of hydrolyzable sites all of which are hydrolyzable alkoxy groups, the hydrolyzing of the epoxy silane being carried out with less than 1.5 equivalents of water, said water being continuously fed during the hydrolysis reaction.
Abstract:
A layered heater structure including an electrode layer and a localized tuning method for tuning the electrode layer of a layered heater structure with high precision is provided. The localized tuning method tunes the electrode layer to its proper local resistance to minimize temperature offsets on the heater surface and thus provide a desired thermal profile that is in marked contrast to conventional, non-localized resistance tuning approaches based on thickness trimming practices, such as grinding or blasting, or resistivity adjustment, such as local heat treatment.
Abstract:
In one embodiment herein there is provided a composition comprising (i) one or more unsaturated silane compounds according to the Formula (1): G1R1SiX1X2 (1) wherein G1 is an olefinically unsaturated hydrocarbon group optionally heteroatom-substituted with one or more oxygen and/or nitrogen atoms; R1 is selected from the group consisting of alkyl, aryl, aralkyl and arenyl; each of X1 and X2 is independently a hydrolyzable group or alternatively each of X1 and X2 is a hydrolyzable group having a direct bond to the silicon atom and also simultaneously a direct bond to each other to form a ring with the silicon atom of the unsaturated silane of Formula (1); and (ii) a system of at least two peroxides comprising a first peroxide having a first 0.1 hour half-life temperature and a second peroxide having a second 0.1 hour half-life temperature, the first and second 0.1 hour half-life temperatures in said composition having a temperature differential of at least about 5° C. In another embodiment herein there is provided a process for producing a silane-grafted thermoplastic polymer. In yet a further embodiment herein there is provided a process for producing a crosslinked thermoplastic polymer. In yet an even further embodiment there is provided an article.
Abstract:
A moisture-curable silylated resin possessing improved storage stability and short cure time is obtained by reacting a prepolymer with a silylating reactant comprising silane (i) possessing three methoxy groups, silane (ii) possessing three alkoxy groups independently containing from 2 to 4 carbon atoms, and, optionally, silane (iii) possessing two methoxy groups and one alkoxy group of from 2 to 4 carbon atoms and/or silane (iv) possessing one methoxy group and two alkoxy groups independently containing from 2 to 4 carbon atoms.
Abstract:
There is provided silicone gel-forming composition comprising a unique combination of polyorganosiloxane and organohydrogenpolysiloxane, which can produce silicone gel with improved hysteresis.
