The water resistant agent NS666K is a formaldehyde free water soluble polyamide synthetic resin, which is suitable for high-speed coating machine and calcium carbonate based coating formula. It can improve the porous property of coating layer, improve ink absorption, reduce wet rejection and wet roughing. The specific characteristics are as follows:
1) Excellent printability improvement effect, especially for reducing wet rejection and improving wet galling strength.
2) Excellent dry galling effect, good cross-linking effect on coated starch, soybean protein and Sb latex. It is especially suitable for coating formulations based on calcium carbonate.
3) Excellent printability, avoid printing blistering and improve ink absorption.
4) It has good compatibility with coating adhesive.
5) There is no formaldehyde release, in accordance with FDA specifications (176.170176.180175.300).
