Abstract:
Flame retardant tackifiers are represented by the formula ′ wherein R represents a hydrocarbyl group having 20 carbons and three consecutive fused six-membered rings; and each R2 independently represents an alkyl group having from 1 to 8 carbon atoms. Curable compositions contain a curable binder precursor and at least one of the flame resistant tackifiers. Pressure-sensitive adhesives comprises an elastomer and at least one flame retardant tackifier compound represented by the formula ″ wherein R represents a hydrocarbyl group having 20 carbon atoms and three consecutive fused six-membered rings and each R1 independently represents an alkyl or aryl group having from 1 to 8 carbon atoms.
Abstract:

Abstract:
Described herein are release layers formed via solventless extrusion. The release layers include a polyolefin and an alkyl dimethicone. The release layers exhibit tailorable release properties from pressure-sensitive adhesives. The release layers are simple to make and require no post-treatment in order to impart the observed release properties. The release layers are adaptable to multilayer extrusion, blown film formation, and cast film formation techniques.

Abstract:
Condensation-cure systems comprising at least one silanol-functional polyorganosiloxane and a platinum catalyst are described. The platinum catalysts include Pt(0) complexes, a Pt(II) complexes, and a Pt(IV) complexes. Condensation-cure systems comprising two or more silanol-functional polyorganosiloxanes are described, as are systems comprising a silanol functional polyorganosiloxane in combination with hydride-functional silanes or alkoxy-functional silanes. Articles incorporating cured condensation-cure systems are also disclosed.
Abstract:
Photoactivated, precious metal catalysts in combination with condensation-cure silicone systems are described. Curable compositions including hydroxyl-functional polyorganosiloxanes, hydride-functional silanes, and a catalyst comprising a precious metal complexed with an actinic-radiation-displaceable ligand are described. Methods of curing such compositions and the resulting cured compositions are also discussed.
