摘要:
Coated article has a thermoplastic substrate and a surface coating of a transparent ultraviolet light-resistant polymer which is the reaction product of a melamine compound, a polyol, and a multimeric benzotriazole compound. The coating of the coated article retains its UV absorbance during curing and exposure to elevated temperatures.
摘要:
Low viscosity MQ silicone resins as a composition of matter, methods of preparation of same and cosmetic and personal care products comprising said MQ resins.
摘要:
Silicone pressure sensitive adhesive compositions are provided which are free of volatile organic solvents. Silicone fluids in the form of cyclic or linear organosiloxanes, and having a boiling point at atmospheric pressure of 250.degree. C. or less, are used in combination with an organopolysiloxane gum and an organosiloxane hydrolyzate of SiO.sub.2 units and triorganosiloxy units.
摘要:
Novel coating compositions contain a radiation polymerizable acrylic monomer or oligomer and an ultraviolight-light absorbing effective amount of a UV-absorbing multimeric benzotriazole compound.
摘要:
A method is provided for making a heat curable organopolysiloxane composition, such as a pressure sensitive adhesive composition by blending a benzene soluble resinous copolymer in the form of a spray dried particulate, comprising triorganosiloxy units, such as trimethylsiloxy units, and SiO.sub.2 units with a fluid network mixture of an alkenyl siloxane, a silicon hydride siloxane and a hydrosilylation catalyst.
摘要:
A process of producing a thermoplastic article having resistance to degradation by ultraviolet radiation, which comprises impregnating the surface of the thermoplastic article with a UV-absorbing effective amount of a solution of a multimeric benzotriazole compound at a surface impregnation effective elevated temperature.

摘要:
A free flowing silicone powder having a primary particle size in the range of 0.1-200 nm and an aggregate size of 10 nm to 200 microns which is a product formed by spray drying an organic solvent dispersion of an organosiloxane hydrolyzate having triorganosiloxy units and tetrasiloxy units.
摘要:
Organophosphorus compounds capable of being activated with light at from 360 nm to about 410 nm, such as, an acylphosphine oxide, have been found useful as photoinitiators for effecting the cure of various UV curable coating compositions, such as a UV curable organic material in the presence of up to 20% by weight of a UV absorber. UV stabilized thermoplastic composites of films, sheets, or laminates having thickness of up to an inch or more with improved optical clarity also are provided.
