摘要:
A novel silicone-acrylic copolymer which comprises a covalently bonded silicone polymer with an acrylic polymer through the —Si—O—Si— linkage is described. The silicone-acrylic copolymer is a reaction product of (a) a silicone polymer, (bi) a mixture of acrylic monomers wherein at least one acrylic monomer comprises a silane (meth)acrylic monomer and/or a siloxane (meth)acrylic macromer with a radical initiator to form an acrylic prepolymer or (bii) an acrylic polymer which comprises a silane or a siloxane functional group; and (c) a scrambling catalyst, wherein the ratio of the silicone polymer (a) and the mixture of acrylic monomers (bi) or polymer (bii) is from 50:1 to 1:50. The silicone-acrylic copolymer is useful as an adhesive, sealant, coating, and the like.

Combinations of alkyl siloxy siloxane-containing polymers admixed with liquid polydimethylsiloxanes are excellent non-stinging, non-irritating liquid coating material for forming films which act as conformable bandages adhering to and protecting nails, skin and mucous membrane wounds from abrasion, contamination, and desiccation, while stopping pain from exposed nerve ends and allowing body fluid evaporation.

Described herein are glass articles and methods of making glass articles, comprising a thin sheet and a carrier, wherein the thin sheet and carrier or bonded together using a coating layer, which is preferably an organosiloxane polymer coating layer, and associated deposition methods and inert gas treatments that may be applied on the thin sheet, the carrier, or both, to control van der Waals, hydrogen and covalent bonding between the thin sheet and the carrier. The coating layer bonds the thin sheet and carrier together to prevent a permanent bond at high temperature processing while at the same time maintaining a sufficient bond to prevent delamination during high temperature processing.

Provided herein is a method for coating a surface. The method comprises providing a towelette moistened with a mixture of constituents to form a non-aqueous silicon-based composition comprising 7% to 80% (w/w of the total composition) polysilazane, 1% to 10% (w/w of the total composition) polysilane, 0.2% to 1% (w/w of the total composition) polysiloxane, and 20% to 70% (w/w of the total composition) at least one organic solvent; wherein polysilazane is present in a 10:1 to 110:1 weight ratio to polysiloxane; and wherein the polysilane is of a formula (R1R2Si)n, wherein n is greater than 1, and wherein R1 and R2 are the same or different and are chosen from alkyl, alkenyl, cycloalkyl, alkylamino, aryl, aralkyl, or alkylsilyl. The mixture from the towelette to form a coating on a surface and the coating is cured ambiently without additional heat. Also provided are towelettes containing the mixture.
摘要:
The present invention relates to coating composition. And in particular, to an inorganic coating composition which can be cured at low temperature and a preparation method thereof. In order to solve the problems that the organic coating is harmful for the environment, the inorganic coating has bad flexibility, and the traditional ceramic coatings need heat and is inconvenient for curing in prior art, the present invention provide an inorganic coating composition which can be cured at low temperature and a preparation method thereof. The inorganic coating composition comprises the ingredient as below: 70-80 wt % of inorganic solution; 5-10 wt % of functional additives, which are potassium titanate, alumina, or a compound thereof; 10-20 wt % of inorganic pigment; 0.5-2.0 wt % of other functional additives. The said inorganic solution comprises the following ingredients: 30-40 wt % of organic alkoxy-silane, 15-20 wt % of organic solvent, and 25-30 wt % of silica sol. The inorganic coating composition is able to be cured at low temperature, the film formed by it has excellent flexibility, and the film will not release harmful organic gases, and is beneficial to the environmental.
