The present invention provides anaerobic adhesive compositions, reaction products of which demonstrate controlled-strength at ambient temperature conditions and enhanced resistance to thermal degradation at elevated temperature conditions. The compositions are (meth)acrylate- and/or polyorganosiloxane-based and may include one or more of a variety of other components, such as certain coreactants, a maleimide component, a diluent component reactive at elevated temperature conditions, mono- or poly-hydroxyalkane components, and other components.
摘要:
The present invention is directed to silicone formulations which are capable of being rapidly cured to tough elastomeric materials through exposure to UV radiation, and optionally through exposure to moisture as well. The cured products demonstrate high resistance to flammability and combustibility. The flame-retardant components is a combination of hydrated alumina and an organo ligand complex of a transition metal or an organosiloxane ligand complex of a transition metal or a combination thereof.

摘要:
The invention provides a conductive, resin-based composition, which includes a resinous material, and a conductive filler dispersed therein. The conductive filler includes a first conductive filler component and a second conductive filler component. The particles of the first conductive filler component are harder than those of the second conductive filler component, when measured using the Mohs hardness scale. The composition is subjected to shear mixing forces which shearingly disperse the first and second conductive filler components throughout the resinous material in such a way that the particles of the second conductive filler component occupy the interstitial voids within the network of first conductive filler component particles contained in the resinous material and thereby enhance conductivity.
