摘要:
The process of controlling foam in a foam-generating system by adding to the system a foam-inhibiting effective amount of a block copolymer containing alkylene oxide units obtained by reacting a homopolymer or copolymer of alkylene oxides with a diisocyanate or a dicarboxylic acid derivative containing 2 to 44 carbon atoms.

An aqueous fatty alcohol dispersion containing: (a) 5% to 40% by weight of a Cl.sub.10 -C.sub.28 fatty alcohol; (b) 0.5% to 5% by weight of anionic interfacially active compounds; (c) 0.5% to 5% by weight of nonionic interfacially active compounds comprising the reaction products of ethylene oxide with alkane-1,2-diols containing 6 to 18 carbon atoms, and (d) the balance, water. The dispersion is useful as an antifoam agent.

摘要:
An aqueous thickener composition containing an organic water-dispersible or water-soluble polymeric thickener and a viscosity reducer comprising a compound corresponding to formula (1):R.sup.1 --O--(R.sup.2 --O).sub.n --H (1)in whichR.sup.1 is an aliphatic hydrocarbon radical containing 8 carbon atoms,R.sup.2 represents an alkylene radical containing 2 to 4 carbon atoms, andn is an integer of 3 to 7.
摘要:
The invention is a method for improving the flow of particulate lacquer powders when the lacquer powders are coated on a substrate and the substrate heated to fuse the lacquer particles to provide a finished lacquer surface on the substrate. The flow control agent is an oxazine, oxazoline, oligoxazine or oligoxazoline and salts of the compounds with protonic acids. The flow control agents when included in power lacquer formulations improve the flow of the lacquer when the powder lacquer coated substrate is heated to fuse the coating.
摘要:
Dispersant compositions are described which contain: (a) a carrier medium comprising a ternary mixture of diisobutyl esters of succinic acid, glutaric acid and adipic acid, the carrier medium present in an amount of from 10 to 80% by weight based on the composition; and (b) one or more polyurethane dispersants present in an amount of from 20 to 90% by weight based on the composition.
摘要:
A process for controlling the deposition of stickies from paper stock suspensions in papermaking involving the steps of: (a) providing a paper stock suspension containing stickies; and (b) contacting the stickies in the paper stock suspension with a native starch.
摘要:
The invention provides microcapsules having an average diameter of 0.1 to 25 μm, obtained by a process (a) or (b), wherein, (a1) preparing an aqueous emulsion comprising actives and optionally oil components and/or emulsifiers; (a2) treating the emulsifier with an aqueous solution of anionic polymers to form a matrix; (a3) contacting the matrix with an aqueous solution of cationic polymers to form a capsule and optionally (a4) separating the aqueous phase from the capsules, or (b1) preparing an aqueous emulsion containing actives and optionally oil components and/or emulsifiers; (b2) treating the aqueous emulsion with an aqueous solution of cationic polymers to form a matrix; (b3) contacting the matrix with an aqueous solution of an anionic polymer to form a capsule and optionally (b4) separating the aqueous phase from the capsule. The microcapsules are useful in paint and lacquer formulations.
