摘要:
An emulsion is made by dispersing a siloxane in water by forming a mixture of water, a cyclic siloxane and an ethoxylated alcohol nonionic surfactant. An organosilanolate initiator is used and the mixture is free of other surfactants which bear a charge. The cyclic siloxane is polymerized until an emulsion is formed and the emulsion is free of electrical charge. The emulsion is more compatible in the personal care arena.
摘要:
Fluorescent organopolysiloxane compounds which bear two or more reactive silicon-bonded sites are useful as durable markers in curable silicone compositions. Having more than one reactive site the compounds participate in the curing reaction of the curable composition and thus do not adversley affect its curing behavior. The resulting fluorescent curable compositions are particularly useful in the preparation of adhesive-release coatings.
摘要:
Novel silicone acrylate polymers and a method for their preparation is disclosed. These polymers are formed from silicone acrylates, silicone diacrylates or mixtures with organic acrylates. The copolymer formed from the reaction mixture of silicone acrylates and organic acrylates is useful in enhancing glass reinforced polyesters.
摘要:
A process of curing and cross-linking methylhydrosiloxanes by contacting and forming a mixture of an allyl amide with at least one methylhydrosiloxane in the presence of a Group VIII metal catalyst and heating the mixture of the allyl amide, the methylhydrosiloxane and the Group VIII metal catalyst, in the presence of ambient moisture until the methylhydrosiloxane becomes cured and cross-linked.
摘要:
The present invention relates to coating compositions containing multifunctional acrylate monomers, organic compounds and colloidal silica. Silanes are absent from these coating compositions. Transparent, abrasion resistant coatings result from the cure, either by ultraviolet light or electron beam radiation, of these compositions.
摘要:
The present invention relates to a novel coating composition containing alkoxy-functional silanes and colloidal silica to which hydroxyacrylates have been added. This coating composition may be applied to solid substrates and thermal cured to form a substantially clear, abrasion resistant layer. The composition has particular utility as an abrasion resistant coating for plastics, especially polycarbonate, without the need for primers.

摘要:
The present invention relates to catalyst compositions and methods for the preparation thereof. More particularly, the present invention relates to novel rhodium catalyst complexes compositions useful for crosslinking of compositions containing methylhydrogensiloxanes. The present invention further relates to a method for the preparation of these catalyst complexes and to their use in emulsions of methylhydrogensiloxanes for treatment of textile fibers or fabrics.
