The invention relates to new &#x3b2;-hydroxyalkylamides, to a method for production of same and to the use of same.

&#x3b2;-hydroxyalkylamides, a method for production of same and use of same

The invention relates to novel &#x3b2;-hydroxyalkylamides, to a method for their production and to the use thereof.

Beta-hydroxyalkylamides, method for their production and use thereof

The invention relates to prepregs and composite components (molding) produced therefrom at a low temperature, obtainable by using powdery highly reactive polyurethane compositions containing uretdione groups, with specific catalysts.

Prepegs and molded bodies produced thereof at low temperature

The invention relates to a process for the solvent-free, continuous preparation of polyureas by reacting at least one isocyanate and/or isocyanurate having at least two NCO groups with at least one diamine and/or polyamine in an extruder, intensive kneader, intensive mixer or static mixer by thorough mixing and rapid reaction by briefly heating and subsequent cooling to isolate the end product.

Process for the solvent-free, continuous preparation of polyureas

A polyurethane composition comprising: A) from 3 to 35% by weight of a polymeric composition comprising B) from 15 to 45% by weight in the polymeric composition A), based thereon, of at least one amorphous and/or crystalline polyester having an OH number of from 10 to 250 mg KOH/g; C) from 7 to 25% by weight in the polymeric composition A), based thereon, of at least one curing agent based on blocked polyisocyanates, isocyanurates and/or uretdiones having a functionality of at least 1.7; D) from 1 to 50% by weight in the polymeric composition A), based thereon, of auxiliaries and additives; there being from 0.6 to 1.2 NCO groups per OH group of A) and B).

Powder coatings based on thermoset-modified polymers and polyesters

The use of pulverulent thermosetting coating compositions based on physical mixtures of individual isocyanato isocyanurates formed from aliphatic and (cyclo)aliphatic and/or cycloaliphatic diisocyanates and from polyesters containing hydroxyl groups and terephthalic acid for coil powder coating materials, to a process for producing such coatings, and to the metal coils coated with such coating materials.
