Product Description

160 Degree Curing Polyester Resin, 95:5 HAA Polyester Resin with Excellent Leveling
NH6562 is a saturated carboxyl polyester resin for polyester/primid powder coating system at the ratio 95:5.
As a solvent-free solid coating, powder coatings have almost zero VOC emissions and greatly reduce environmental pollution. Among them, the polyester/hydroxyalkyl amide (HAA) system does not pose a threat to human health due to the non-toxicity of HAA and has the advantage of being more environmentally friendly.
However, the curing temperature of most systems in powder coatings is 180-200°C, and high temperature means higher energy consumption, which is not conducive to energy saving. NH6562 can achieve low-temperature curing, which can not only reduce more energy consumption and save a lot of energy to greatly reduce costs, but also expand the application field of powder coatings.
