A method for facilitating the removal or preventing the adherence of residual oil in oil tankers and other vessels or containers, on the surfaces of oil spill cleanup equipment such as skimmers and booms, and on sucker rods or other surfaces in oil wells, by coating surfaces contacting the oil with a film of a polymer that prevents or reduces oil adherence. Materials effective in reducing oil adherence are oleophobic films formed by complexing a polyacrylamide or carboxymethylcellulose with salt...

There is disclosed the coating of a metallic substrate with a cross-linked polymeric film by contacting the substrate with an aqueous composition containing: at least an acrylic or metacrylic compound which can be defined by the general formula: ##STR1## wherein: R is a straight-line or branched aliphatic hydrocarbon radical, either saturated or unsaturated containing from 2 to 10 carbon atoms, or a cycloaliphatic or an aromatic group; R.sub.1 and R.sub.2, equal to or different from one another,...

A method of minimizing the degradative or corrosive effect of ionic materials on solid substrate surfaces comprising coating such surfaces with a curable composition comprising essentially (1) a polyepoxide and (2) an oxazine or oxazoline curing agent.

The adhesion to metal surfaces of room temperature vulcanizable silicone rubber curable through condensation of silicon-bonded hydroxyls with silicon-bonded alkoxy radicals is improved by contacting the metal surface with dimethyl-formamide or an aqueous solution of glycine, removing the glycine or dimethylformamide, drying, thereafter applying the room temperature vulcanizable silicone rubber to the treated surface and allowing it to cure.

A composition of a vinyldiorganosiloxy endblocked polydimethylsiloxane and a mixture of an organosiloxane having five to 20 silicon atoms per molecule and an average of at least three silicon-bonded hydrogen atoms per molecule and a modified organosiloxane having six to 21 silicon atoms per molecule, an average of at least two silicon-bonded hydrogen atoms per molecule and an average of at least one unit of (RO).sub.3 Si(CH.sub.2)x(CH.sub.3)SiO, (RO).sub.3 Si(CH.sub.2)x(CH.sub.3).sub.2 SiO.sub.0...

The adhesion to metal surfaces of room temperature vulcanizable silicone rubber curable through condensation of silicon-bonded hydroxyls with silicon-bonded alkoxy radicals or silicon-bonded hydrogen atoms is improved by contacting the metal surface with acetic acid, formic acid, propionic acid, butyric acid, benzoic acid, toluic acid, metal salts thereof and ammonium salts thereof, removing any excess acid or salt from the surface along with any extraneous materials formed during the contacting...

The adhesion to metal surfaces of room temperature vulcanizable silicone rubber curable through condensation of silicon-bonded hydroxyls with silicon-bonded alkoxy radicals is improved by contacting the metal surface with aqueous solutions of sodium ammonium or potassium salts of chlorides, iodides, bromides, bicarbonates, sulfates, dihydrogenphosphates, monohydrogenphosphates, tetraborates, perchlorates, nitrates or nitrites, rinsing the surface, drying, thereafter applying the room temperature...

The use of pulverulent thermosetting coating compositions based on physical mixtures of individual isocyanato isocyanurates formed from aliphatic and (cyclo)aliphatic and/or cycloaliphatic diisocyanates and from polyesters containing hydroxyl groups and terephthalic acid for coil powder coating materials, to a process for producing such coatings, and to the metal coils coated with such coating materials.

The present invention relates to a coating composition comprising (A) at least one hydroxyl-containing component which [lacuna] of (A1) from 5 to 60% by weight of at least one polyester and (A2) from 40 to 95% by weight of at least one polyacrylate resin which has been prepared at least partially in the presence of component (A1) and (B) at least one crosslinking agent, characterized in that component (A2) is obtainable from the monomer units: (a) a cycloaliphatic ester of (meth)acrylic acid, (b...

A multipackage system for providing a refinish coating composition and a method for applying the same onto a substrate. The method comprises separately transporting at least one component under pressure to a proportioning device which provides a controlled volumetric ratio of the components. The components of the coating composition are then mixed and coated onto the substrate at ambient temperature or, to accelerate curing, at moderate temperatures. The compositions involve new or modified exis...
