Application

1. It is a kind of synthetic polymer compound with excellent performance, because of a
variety of active functional groups in the molecule, it has the characteristics of high charge density, low surface energy, etc. It is equipped with dispersing, wetting, film-forming, colloid protection and other functions at the same time.
2. It is used as dispersant in the production of carbonless copy paper, and has excellent performance in the even distribution of particle size of microcapsules and protection of colloid.
3. It is used as reinforcing agent in paper, which can obviously improve the gloss and strength of paper such as coated paper, and can also be used as dispersing stabilizer of ink.

Packing and Storage
Packing: In 25kgs net paper bag.
Storage: Keep container tightly closed in a dry and well-ventilated place.
