Erweichungspunkt von 20° bis 150°C, bestimmt mittels Differential-Thermo-Analyse und mit einer Säurezahl von 10 bis 150 mg KOH/g Substanz und B) mindestens einem N,N',N"-Triglycidyl- triazolidin-3, 5-dion mit einem Epoxidwert von 0,6 bis 1,13; A und B sind in einem solchen Verhältnis abgemischt, daß auf eine Carboxylgruppe 0,5 bis 1,5 1,2-Epoxidgruppen entfallen, sowie ein Verfahren zu ihrer Herstellung.
Abstract:
A water-based coating composition which emits very little pollutants on curing to a water-resistant coating comprises a synthetic resin containing free carboxyl groups held in solution or stable dispersion in water by an amine. The amine is a tertiary carbinamine containing at least two hydroxymethyl groups bonded to the carbon atom carrying the amine group. The coating compositions react with formaldehyde to produce stable fluid emulsion coating compositions having similar properties on curing. The coating compositions are used to coat substrates.

Abstract:
The present invention provides a product and a manufacturing process for an aqueous dispersible dendritic polymer with various functionalities, and polymer compositions and polymer formulations comprising such a dendritic polymer. The aqueous dispersible dendritic polymer composition comprises a hydrophilic functional group to allow dispersion in aqueous solvents and improve washability of the polymer, a low surface tension functional group to impart resistance to dirt pick-up and optionally, a curable functional group to allow superior cross-linking capabilities and optionally, a softening functional group to impart flexibility to the composition.
