Hybrid polyester resin for indoor use HH2782G Good storage stability and balance of properties TMA free
HH2782GT is tribo version of HH2782G, it is a carboxyl polyester resin designed for 70/30 hybrid powder coatings with excellent gas oven stability. Can be used with B68 for low gloss with good performance.
Powder coatings are solvent-free, non-polluting, recyclable, environmentally friendly, save energy and resources, reduce labor intensity, and have high mechanical strength of the coating film, so they have developed rapidly and are widely used in home appliances, automotive coatings, aluminum alloy doors, and windows, as well as metal and non-metallic coatings. Metal exterior decorative paint protection. At present, there are basically three heating methods on the coating production line: electric heating, gas heating, and oil heating. In many areas of our country, due to the shortage and high cost of industrial electricity, diesel, natural gas, etc. are widely used as heat sources for heaters in coating lines. However, directly heated by a gas furnace, the baking of the gas will affect the surface color of the powder coating, thereby affecting the final coating effect.
