Abstract:
The process to prepare a storage stable aqueous co-dispersion of epoxy resins and at least a silane oligomer is given. This aqueous co-dispersion of epoxy resins with a silane as part A, of a curable paint composition in which the part B comprises a hardener and optionally pigments and additives. This epoxy resins with the silane provide equal performance even after several months' storage.
Abstract:
Disclosed are bonding agents useful in the production of pelletized or briquetted fuels. The bonding agents may be incorporated into a feed containing the fuel material, providing both adhesion and cohesion of the fines to produce a uniform and predictable pellet or briquette. Specifically, the bonding composition contains a solubulized starch, a sugar source and/or a diol or polyol compound, and optionally a polymer selected from polyvinyl alcohol (PVOH), PVOH copolymers, polyvinyl acetate (PVA), polyvinyl acetate copolymers (PVAc), ethylene vinyl acetate (EVAc or VAE) or any subset or combination of such polymers. Also disclosed are methods of preparing the bonding agents and to densified and/or torrefied biomass products prepared therewith.
Abstract:
The invention relates to compositions of polyester polyol resins comprising a mixture of α,α-branched alkane carboxylic acids glycidyl esters with a defined isomeric composition where the sum of the concentration of the blocked and of the highly branched isomers is at least 50%, preferably above 60% and most preferably above 75% on total composition.
Abstract:
Embodiments of the invention are directed to materials suitable for use as proppant materials. Proppant materials, and methods for making proppant materials, are provided. In one embodiment, the proppant material comprises a substrate material, a polymeric material disposed on the substrate material and a surface wettability modifier disposed on the polymeric material. Methods of making and using the proppant materials are also disclosed.
Abstract:
Compositions and methods for forming surfactants, aqueous dispersions, and curing agents are provided. In one aspect, the invention relates to improved epoxy functional surfactants prepared by reaction of an epoxy composition and an amidoamine composition formed from a blend of acid-terminated polyoxyalkylene polyols. The improved epoxy functional surfactants may be reacted with an excess of epoxy composition and water to result in an aqueous dispersion. The amidoamone composition may be a reaction mixture of a diamine compound and an acid terminated polyoxyalkylene composition formed from two or more polyoxyalkylene polyol compounds. The epoxy functional surfactant may be reacted with amine compounds to form a compound suitable as a curing agent.
Abstract:
This invention relates to a Waterborne Polyurethane Dispersions (WPU) derived from the reaction products of tertiary alkyl glycidyl esters based hydroxyl terminal polyester polyols with polyisocyanates and chain extended with poly-functional amines and dispersed in water have shown the surprising inherent ability for self-coalescence. Furthermore the cured films have shown improved hardness and abrasion resistance over these benchmarks with a significant reduction in coalescing solvent needed to accomplish film formation.
Abstract:
The invention relates to compositions of polyether polyol resins (hydroxyfunctional oligo or poly ether) comprising a mixture of α,α-branched alkane carboxylic glycidyl esters derived from butene oligomers characterized in that the sum of the concentration of the blocked and of the highly branched isomers is maximum 55%, preferably below 40%, and most preferably below 30% weight on total composition.
