Coatings are often additionally crosslinked to improve their performance characteristics. The anionic type RUCOPUD B-FX 21 (40%) as well as the non-ionic RUCOPUD B-FX 41 (40%) is used as formaldehyde-free crosslinking components for aqueous polymeric dispersions of polyurethanes, polyacrylates or polyvinyl acetates. *)
Moreover, RUCOPUD B-FX 21 and RUCOPUD B-FX 41 are suitable boosters for non-ionic or anionic fluorocarbon water-repellent agents (acrylate or PU types).
In contrast to the majority of well-known types, RUCOPUD B-FX 21 and RUCOPUD B-FX 41 are free of N-methylene-2-pyrrolidone (NMP), butanone oxime and formaldehyde. Thermal activation deblocks and initiates the crosslinking effect.
The blocked isocyanates RUCOPUD B-FX 21 and RUCOPUD B-FX 41 enable the manufacture of stable product formulations as well as pot-life-free recipes.
