Abstract: Dialdimines of formula (I) and emulsions and uses thereof. In particular, they can be used for the preparation of pasty curing agent or accelerator components for polymers having isocyanate groups, which lead to very high early strength, which have good flow behavior on pumping and which can be formulated without VOC solvents, in particular without N-alkylpyrrolidones. These components can be homogeneously or inhomogeneously mixed in an outstanding manner, in particular in a laminar manner, with components which contain polyurethane polymers having isocyanate groups, the two-component compositions thus obtained curing rapidly, having extremely high early strength and remaining without annoying weaknesses.

Abstract: A blocked amine as curing aid for polymers containing isocyanate groups and having a low monomeric diisocyanate content, obtained from the reaction of at least one monomeric diisocyanate with at least one polyol in an NCO/OH ratio of at least 3/1, followed by removal of a majority of the monomeric diisocyanates by means of a suitable separation method, and to the moisture-curing polyurethane compositions obtained from this use. The use enables storage-stable, moisture-curing polyurethane compositions which can be safely handled even without special safety precautions and can be sold without hazard labeling in many countries, have good processibility and cure reliably and rapidly at ambient temperatures to give a material of high strength, elasticity and extensibility, and high stability to weathering influences. Such moisture-curing polyurethane compositions are particularly suitable as elastic sealants, adhesives or coatings, especially also for exposed outdoor applications.

Abstract: A thixotropic agent for increasing the yield point of a curable composition, wherein the thixotropic agent includes (i) at least one urea compound from the reaction of at least one isocyanate with at least one amine and (ii) at least one polyether having blocked hydroxyl groups. The thixotropic agent is preparable in a simple manner and forms a spreadable paste which is firm at room temperature. It is particularly suitable as a constituent of moisture-curing polyurethane or SMP compositions, giving a good increase in the yield point thereof, without adversely affecting storage stability or migration characteristics. It enables phthalate-free adhesives, sealants or coatings that have surprisingly good conveyability coupled with a high yield point, and do not cause any problems with odor or fogging.
