TGIC Curing Blended Polyester Resin 95/5 Outdoor Use Good Flow

Powder Paint Polyester resin NH8001&NH8505 with TGIC Curing Dry-blended for 25-40% Gloss

◇ Applications:

NH8001/NH8505 are saturated carboxyl polyester resins for low gloss polyester/TGIC powder coatings by a dry blend procedure.

Advantages of powder coatings

1. Health and environmental protection

All kinds of liquid chemical harmful film-forming, dispersion, wetting, leveling, anti-corrosion and anti mildew additives added to achieve coating performance are omitted.

2. Convenient transportation and storage

Ordinary coatings contain about 20-50% water or solvent, while powder coatings are completely solid without water or solvent, which is convenient and safe for transportation. In addition, coatings containing water or solvent tend to freeze when the transportation and storage temperature is lower than 0 ℃. This problem does not exist in powder coatings.

3. No preservative is required

In the traditional liquid coating, there is both water and bacterial food, which is easy to be polluted by bacteria. Therefore, in order to prevent deterioration, preservatives should be added, while latex powder coatings have no bacterial pollution and do not need preservatives

4. Paint smell

Compared with the general traditional coating smell residue, this coating can disperse quickly, which can be said to disappear immediately.
