Product Description:

NOVOC™ series are anionic, water-dispersible high molecular weight polyester products. This series of products has excellent dispersion effect on fine particles and stable dispersion with using of water as a medium. They do not contain surfactants such as emulsifiers. It is non-combustible, with small odor, good for energy saving and environmental protection.It is easy to operate, etc. Same as the solvent-based polyesters, NOVOC™ can be cured and cross-linked with isocyanates, amino resins, etc. to obtain good adhesion strength. NOVOC™ series products can not only perform surface pretreatment on substrates such as paper, plastic film, leather and aluminum foil, but also perform amazingly in the textile industry because of their strong adhesion to polyester fibers, nylon fibers and fabrics. In additional, the use of NOVOC™ series products can reduce VOC emissions during the production processing, which is more conducive to environmental protection and human health compare with other solvent-based products.


-       The same superior performance of solvent-based polyester with high bonding strength;

-       Stable pH and viscosity;

-       Anionic, can be stably dispersed in water-based systems;

-       Good water resistance, heat resistance and good durability;

-       The solution appears as transparent, unclear, turbid, emulsion, gel, and layered;

-       Good flexibility;

-       Water-dispersible resin, self-emulsifying, without neutralizer like amine and ammonia;

-       Low VOC, good for environmental protection.
