Abstract:
A silicone composition comprising a formula: (M1)a(D1)b(D2)c wherein M1=R1R2R3SiO1/2; D1=R4R5SiO2/2; and D2=R6R7SiO2/2; wherein R1 is independently at each occurrence a monovalent hydrocarbon radical comprising a reactive end- group other than an amino group; R6 comprises a monovalent poly(oxyalkyl) hydrocarbon radical; and R2, R3, R4, R5, and R7 are independently monovalent hydrocarbon radicals; wherein a, b, and c are stoichiometric subscripts that are zero or positive subject to the following limitations: a is greater than or equal to 2; c is greater than or equal to 1; and when b=0, a+c is greater than or equal to 3 is disclosed.
Abstract:
The invention relates to curable, storage-stable silicon-containing compositions reinforced with functionalized silica useful as one and two-part sealant and adhesive systems. The cured compositions provide silicon-containing rubber having excellent translucency, physical properties and primerless adhesion.
Abstract:
An apparatus is provided for vaporizing a source of vaporizable substance for delivering an aerosol. The vaporizing apparatus comprises a housing defining a first combustion chamber, a second vaporizing chamber for receiving the vaporizable substance, and a transverse wall spanning the interior of the housing for separating the first chamber and the second chamber. A heat transfer element, comprising an elongated member of heat conductive material, extends from the first chamber through the wall and into the second chamber in heat transfer relation with the vaporizable substance for transferring heat from the first chamber to the vaporizable substance. A gas burner disposed in the combustion chamber converts fuel gas to a flame for heating the combustion chamber and the heat transfer element. The heat transfer element maintains the temperature in the second chamber at or above the vaporization temperature of the substance.
Abstract:
The invention relates to a high thermal efficiency, insulated glass unit structure sealed with a cured composition containing, inter alia, diorganopolysiloxane(s) and organic nanoclay(s), the cured composition exhibiting low permeability to gas(es).
Abstract:
The invention relates to an insulated glass unit having an increased service life. An outer glass pane and inner glass pane are sealed to a spacer to provide an improved gas impermeable space. The glass unit includes a curable two-part sealer composition which, upon curing, exhibits unexpectedly high adhesion to substrates.
Abstract:
A composition includes a polycarbonate-polysiloxane block copolymer that has at least one polycarbonate block and at least one polysiloxane block, and a surface modifying agent that includes at least one polysiloxane segment. Increased levels of the surface modifying agent can be incorporated without compromising high transmittance and low haze. The compositions also exhibit improved hemocompatibility and are therefore useful for a variety of articles that may contact blood.
Abstract:
Disclosed are methods and systems that include receiving data associated with the compliance of a user with a self-care regimen, evaluating the data to determine a level of compliance of the user with the self-care regimen, and using at least one executable processor application to provide the user with an incentive based on the determined level of compliance.
Abstract:
Operation methods and systems for distributed generation from a plurality of generators, and computer readable media. One method comprises the step of applying a forward looking matching algorithm to determine a matching matrix with elements mi,j denoting the fraction of generator i's predicted supply assigned to respective load j of a plurality of loads such that a probability of meeting each load's associated power demand characteristic in a next supply cycle satisfies a threshold criterion.
Abstract:
Moisture-curable resin compositions comprising (a) a moisture-curable polymer having at least one hydrolysable silyl group; (b) a reactive modifier; (c) a catalyst for catalyzing the reaction between the moisture-curable polymer (a) and reactive modifier (b) under curing conditions; and cured compositions produced by contacting such resin compositions with water are disclosed. The moisture-curable resin composition is useful in the production of adhesives, including hot melt adhesives, primers, sealants, and coatings.
