Abstract:
The present invention refers a procedure for preparation of a reflective and oxide inhibiting coating consists of adding hard water, a series of compounds such as titanium dioxide, calcium hydroxide at 95%, an acrylic polymer, hydroxy methyl cellulose, sodium hexametaphosphate at 10% y monoethylen glycol, maintaining specific conditions of pH and viscosity during process. The resulting coating of this process, presents highly adhesive actions, as well as a high level of reflection to solar rays, which place it as a oxide inhibitor, that no require previous sealed when it is applied to steel and/or galvanize surfaces.
Abstract:
The present invention provides for a dispersion containing cellulose particles dispersed in a continuous liquid phase comprising a first and a second continuous liquid phase, wherein the first continuous liquid phase consists of a liquid swelling agent or an aqueous solution of said liquid swelling agent, and the second continuous liquid phase comprises, preferably consists of, one or more organic solvents, with the proviso that the one or more organic solvents of the second continuous liquid phase are not capable of dissolving cellulose, have a boiling point higher than the boiling point of the first continuous liquid phase, and are miscible with the constituents of the swelling composition.

Copolymers comprising ethylene, vinyl esters, in particular vinyl acetate and esters of (meth)acrylic acid, selected from esters comprising branched alkyl, cyclic alkyl or optionally alkyl substituted aryl moieties and having a weight average molecular weight of 35,000 g/mol to 150,000 g/mol, formulations of such copolymers in organic solvents and their use as pour point depressant, wax inhibitor and flow enhancer for crude oils.
Abstract:
Water-borne cross-linking polymeric compositions and related embodiments, such as methods of making and using the compositions, as well as products formed with said compositions are described. For example, the water-borne composition may comprise polymers incorporating cross-linking functionality such as, but not limited to, carbonyl or epoxy functionality, and a blocked cross-linking agent, for example, a hydrazone. The cross-linking functionality does not react with the blocked cross-linking agent; however, the blocked cross-linking agent is capable of reacting with the alternative form cross-linking agent such as, but not limited to, a hydrazide, to yield a cross-linked polymer. The alternative form cross-linking agent may be formed in an equilibrium reaction including the blocked cross-linking agent.
Abstract:
A dispersion having from one to sixty percent by weight of total dispersion of a solids component dispersed in an organic continuous phase is useful as a coating for substrates. The solids component contains 40-95 weight-percent of a polyolefin containing only carbon and hydrogen and that has a number average molecular weight that is greater than 400 gram per mole, 5-40 weight-percent of an amine salt of a functionalized polyolefin; and 0-20 weight-percent of optional additives, wherein weight-percent is based on total weight of solids and wherein the dispersed particles have an average particle size of less than 35 micrometers and the organic phase is a dispersion support medium for the polyolefin and amine salt of a functionalized polyolefin.
