Catalysts for solvent-free polyurethane textile coatings - consist of adducts of lactams with hydroxyl cpds., amines, hydrazines or oximes

Catalysts for polyurethane polyaddition reactions, consisting of adducts of (A) lactams of formula: (in which X is OH, R is hydrogen, and m is 0-9, or X is nitrogen, R is an aliphatic, araliphatic or opt. alkyl-substd. pyridine gp. and m is 3) with (B) hydroxyl cpds., amines, hydrazines and/or oxime...

Beschreibung
Zusammenfassung:	Catalysts for polyurethane polyaddition reactions, consisting of adducts of (A) lactams of formula: (in which X is OH, R is hydrogen, and m is 0-9, or X is nitrogen, R is an aliphatic, araliphatic or opt. alkyl-substd. pyridine gp. and m is 3) with (B) hydroxyl cpds., amines, hydrazines and/or oximes. Amount of catalysts used is 0.4-5 (0.6-3) wt. % or the reaction partners. The catalyst is used in the polyurethane coating or impregnating of textiles, bonding of non-woven fabrics or production of polyurethane films by reactive processes, using little or no solvent. Catalysts are liquids and easily metered into the reaction mixt. Hydrolysis resistance is not impaired, as by use of metal oxide catalysts they also act as diluents and solvents for obtaining the required viscosity.
