Anti Yellowing Pinhole Free HAA Low Curing Temperature Polyester Resin NH6563
◇ Applications:
NH-6563 is a saturated carboxyl polyester resin designed for 95:5 Primid XL 552 powder coating to be cured at 160℃.
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.
