Abstract: A description is given of azetidine derivatives and methods for producing them, and of their use as a latent curing component for resins having functional groups which are reactive toward amino groups. The particular advantages of the curing component proposed in accordance with the invention, such as effective producibility, high environmental friendliness, and excellent storage stability of the resin/curing agent mixtures, make these azetidine derivatives outstandingly suitable for one-component, moisture-hardening polymer compositions, which are of special interest in particular for the production of (floor) coatings, sealants, and adhesives.

Abstract: The invention relates to the use of diazepine derivates of general formula (I) and/or (II), wherein R1, R2, R3 and R5 independently represent H, C1-C20-alkyl, C3-C8-cycloakyl, C6-C10-aryl or alkylaryl comprising C1-C4-alkyl and C6-C10-aryl groups, R4?H, C1-C6-alkyl(iden), as latent hardening components for resinous substances comprising functional groups which can react with amines. Based on the particular advantages of the inventive hardening components, such as good producibility, environmentally friendly and having an excellent shelf life of the resin/hardening mixture, said diazepine derivatives are outstanding for single-componented, moisture-hardening polymer masses, which are particularly useful in the production of sealing materials, adhesives and coating materials.

Abstract: A solvent-free polyurethane-polymer hybrid dispersion having a high solids content of polymer or formulation constituents is described, which is obtainable by a) the multistage preparation of a polyurethane base dispersion and b) by the subsequent preparation of a polyurethane-polymer hybrid dispersion. This polyurethane-polymer hybrid dispersion not only is distinguished by complete freedom from solvents and high solids contents in combination with low viscosity and a technically simple preparation process but also has excellent mechanical properties and, owing to the low hydrophilicity, high water resistance.

C. and a pH value of 8.0 to 13.0 as an aqueous solution with a solids content of 20% by weight. The product is obtainable by (a) condensation of amino-s-triazine, formaldehyde and sulfite in a molar ratio of 1:1.9 to 2.9:0.7 to 1.3 in aqueous solution at a pH value of 9.0 to 12.0 and a temperature of 50.degree. to 90.degree. C. until the sulfite is no longer detectable, and (b) subsequent further condensation at a pH value of 2.0 to 5.0 and a temperature of 50.degree. to 100.degree. C. until the viscosity exhibits the desired value.
