Cross-linking Agent for Various Polymers

NK ASSIST FU is a newly developed cross-linking agent which is based on blocked isocyanatechemistry.
NK ASSIST FU imparts excellent durability to various kinds of finishing polymers, such as fluorocarbon, acrylic, resin, polyurethane and polyvinyl alcohol. As NK ASSIST FU is water dispersed and absolutely free from formaldehyde, it is very safe and convenient to use.

Characteristics
1. NK ASSIST FU generates the cross-linking reaction during the heat treatment (usually above 150℃), when polymers are treated on fabrics in conjunction with it.
2. NK ASSIST FU imparts a softer hand than polyfunctional ones such as trimethylo melamine, as it is the bi-functional cross-linking agent.
3. NK ASSIST FU is very safe and convenient to use since NK ASSIST V is water dispersed and absolutely free from formaldehyde.
4. NK ASSIST FU is 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 FU has an excellent compatibility with cationic polymer, although the ionic nature of it is slightly anionic.
