    摘要: Described is a process for preparing a dispersion of microcapsules by condensing a partially methylated melamine-formaldehyde resin having a molar ratio of melamine:formaldehyde:methanol of from 1:3.0:2.0 to 1:6.0:4.0 in water in which the essentially water-insoluble material forming the capsule core is present in dispersion in the presence of an alkali metal salt of a homopolymer or copolymer of 2-acrylamido-2-methylpropanesulfonic acid as protective colloid at a pH of from 3 to 6.5 by preforming the microcapsules at a temperature of from 20 to 50° C. and then curing the capsule wall of the preformed microcapsules at >50 to 100° C., which comprises adding from 5 to 100% by weight of melamine, based on the melamine-formaldehyde resin, in the course of curing. The microcapsule dispersions are formaldehyde-reduced and of low viscosity.

    摘要: Crosslinker compositions consisting essentially of 50 to 95 weight percent monomeric C1 to C8 alkoxymethyl melamine derivatives containing not more than about 0.20 wt. % of imino (>NnullH) groups. Such compositions further comprise 5 to 50 weight percent oligomeric C1 to C8 alkoxymethyl melamine derivatives and are useful for low temperature curing of functional resins, e.g. with active hydroxyl groups, for wood, automotive, appliance, coil and other coatings.

    摘要: A high solids polymer resin coating composition cross-linked with alkylated melamine resins possessing improved intercoat adhesion in multiple coating applications. A mixed methylated isobutylated melamine resin as a cross-linking agent for the high solids polymer resin coating composition surprisingly substantially eliminates intercoat adhesion failure without any negative effects on overall coating properties and performance. The backbone polymer of the composition may advantageously be acrylic resin, a polyester resin or mixtures thereof while the mixed methylated isobutylated melamine resin cross-linking agent is advantageously predominantly monomeric poly(methoxy isobutoxymethyl) melamine resin with an average methoxy content of 1-5 and an average isobutoxy content of 5-1, per triazine.

F. and containing a water-miscible partially etherified melamine formaldehyde cross-linking agent and an acrylic copolymerization product of about 3% to about 8% of an unsaturated carboxylic acid, about 10% to 30% of a hydroxy functional monomer and about 62% to 87% of a nonfunctional monomer. The acrylic copolymer is further characterized as having a glass transition temperature of about -10.degree. C. to 45.degree. C. and a molecular weight of about 2,000 to about 100,000. The aminoplast resin preferably is only partially etherified and contains about 10% to about 30% by weight reactive methylol groups.

    摘要: AN ENCAPSULATION PROCESS IS PROVIDED WHEREIN THE SUBSTANCE TO BE ENCAPSULATED IS DISPERSED IN A LIQUID WITH WHICH IT IS SUBSTANTIALLY IMMISCIBLE IN THE PRESENCE OF A TENSIDE CAPABLE OF FORMING A COMPOUND THAT IS INSOLUBLE IN THE DISPERSING LIQUID AND THEREAFTER THE TENSIDE IN THE DISPERSION, WHICH IS IN ASSOCIATION WITH THE SUBSTANCE, IS CONVERTED INTO THE IRREVERSIBLY INSOLUBLE STATE TO ENCAPSULATE THE SUBSTANCE. PARTICULARLY SUITABLE A TENSIDES ARE THE SURFACE-ACTIVE, CROSS-LINKABLE AMINOPLASTS, PREFERABLY SURFACE-ACTIVE, ETHERIFIED METHYLOMELAMINES OR THE CORRESPONDING METHYLOLUREAS.
