NK ASSIST NY-11
Cross-linking Agent for Various Polymers
NK ASSIST NY-11 is a newly developed cross-linking agent which is based on blocked isocyanate chemistry. NK ASSIST NY-11 imparts excellent durability to various kinds of finishing polymers, such as fluorocarbon, acrylic, resin, polyurethane and polyvinyl alcohol. As NK ASSIST NY-11 is water dispersed and absolutely free from formaldehyde, it is very safe and convenient to use.
-
1. NK ASSIST NY-11 generates the cross-linking reaction during the heat treatment (usually above 150°C), when polymers are treated on fabrics in conjunction with it.
2. NK ASSIST NY-11 imparts a softer hand than polyfunctional ones such as trimethylol melamine, as it is the bi-functional cross-linking agent.
3. NK ASSIST NY-11 is very safe and convenient to use since NK ASSIST V is water dispersed and absolutely free from formaldehyde.
4. NK ASSIST NY-11 is a aliphatic type blocked isocyanate, which is no-yellowing effect on the white fabric.
5. NK ASSIST NY-11 has an excellent compatibility with cationic polymer, although the ionic nature of it is slightly anionic. -
