JH-WH325 SURFACE STRENGTHENING ADHESIVE

1.Product introduction

JH-325 anionic surface-enhancing sizing agent is a new generation of enhanced surface sizing agent developed by our company. It can effectively combine with starch, endowing the starch coating with good crosslinking strength and hydrophobic properties. This product features low dosage, low cost, and ease of use. It has good film-forming properties, significantly improving the surface strength of paper types such as double-sided adhesive paper, electrostatic copy paper, and white cardboard. This product has good compatibility with various chemicals and is compatible with starch, direct dyes, acid dyes, fluorescent whitening agents, and other anionic or nonionic substances.
