Abstract:
The present invention provides a composition containing about 90% to about 30% of at least one amorphous thermoplastic or at least one semi crystalline thermoplastic or a mixture thereof and about 10% to about 70% of expanded graphite, wherein about 90% of the particles of the expanded graphite have a particle size of at least about 200 microns. The inventive compositions may find use in LED heat sink applications.
Abstract:
The present invention relates to a coating composition comprising: a) silanized colloidal silica particles; b) alkyd-containing binder; c) a carrier fluid, wherein the coating composition is essentially free from a cobalt-based drier. The present invention also relates to a method of producing a coating composition and the use of such coating composition for coating of a substrate.
Abstract:
The present invention provides shaped articles comprising one or more composite layer of (i) a vulcanizate encapsulated in a colored or uncolored thermoplastic polymer matrix containing one or more passivating agent, and (ii) a reflective material chosen from colored fluidizable particles of a thermoplastic reflective colorant encapsulated vulcanizate, roofing granules, thermoplastic encapsulated roofing granules, the colored thermoplastic polymer matrix, and combinations thereof. The articles can be laminates of colored or reflective layers on uncolored or other layers, or one or more colored layer having colored fluidizable particles are dispersed within the surface of the uppermost composite layer or having either the colored fluidizable particles or the granules are dispersed on the surface of the composite layer or are adhered thereto with a thermoplastic resin. Roofing shingles are provided.
Abstract:
A coating comprising epoxy functional resin, corrosion resistant particles, and a multi-functional crosslinker are disclosed as are methods of using such a coating to coat at least a portion of a substrate and a substrate coated thereby.
Abstract:
Masterbatch comprising a dimeric and/or trimeric cyclic ketone peroxide dispersed in a polymeric matrix with a porosity, expressed as percentage of voids on the volume of the matrix, of 0.1-80 vol %, wherein said masterbatch comprises, per 100 g of polymeric matrix, 1-30 g dimeric and/or trimeric cyclic ketone peroxide and less than 0.20 g saturated hydrocarbons with 17-51 carbon atoms.
Abstract:
The embodiments described herein generally relate to an electronic communication module suitable for incorporating into a tire or tire retread, where the electronic communication module comprises a radio device having at least a portion of its outer surface surrounded by a rubber composition. Certain embodiments also relate to tires or tire retreads containing the electronic communication module. In addition, certain embodiments relate to methods for improving the readability of a radio device incorporated into a tire or tire retread.
Abstract:
Embodiments of organic peroxide formulations provide significant improvements in surface tackiness (often including tack-free surfaces) when curing elastomers in the presence of oxygen. The peroxide formulations may include, for example, one or more compounds selected from sulfur-containing compounds, organophosphite compounds, HALS (Hindered Amine Light Stabilizer) compounds, aliphatic allyl urethane compounds, and blends comprising nitroxides (e.g., 4-hydroxy-TEMPO) and quinones (e.g., mono-tert-butylhydroquinone).
Abstract:
The invention provides a rubber composition comprising at least a diene elastomer, at least 60 phr of a reinforcing inorganic filler, and 20 to 100 phr of a plasticizer comprising more than 4 phr of a mercapto-modified silicone oil.
