NK ASSISTNY-22
Non-yellowingCross-linking Agent for Various Polymers
NK ASSIST NY-22 is a newly developed non-yellowing cross-linking agent which is based on blocked isocyanate chemistry. NK ASSIST NY-22 imparts excellent durability to various kinds of finishing polymers, such as fluorocarbon, acrylic, resin, polyurethane and polyvinyl alcohol. As NK ASSIST NY-22 is water dispersed and absolutely free from formaldehyde, it is very safe and convenient to use.

1.NK ASSIST NY-22generates 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-22imparts a softer hand than polyfunctional ones such as trimethylol melamine, as it is the bi-functional cross-linking agent.3.NK ASSIST NY-22is very safe and convenient to use since NK ASSIST NY-22is water dispersed and absolutely free from formaldehyde.4.NK ASSIST NY-22is effective not only to synthetic fabrics but also to the fabrics which possess an active hydrogen, such as cotton, blends, silk and wool.5.NK ASSIST NY-22has an excellent compatibility with cationic polymer, although the ionic nature of it is slightlyanionic.
