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.
Features：
- 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.
