Product Description
Low Temperature Cure Powder Coating Polyester Resin for Hybrid Powder Coatings
HH2762 is a carboxyl polyester resin designed for 70/30 hybrid low temperature curing powder coatings.
In recent years, natural disasters caused by global warming have become more and more frequent, prompting the continuous improvement of people's environmental awareness and environmental protection standards. Powder coating fully conforms to the internationally popular 4E (economic, environmental protection, high efficiency, and excellent performance) principles. The energy-saving and emission reduction advantages of low-temperature curing powder coatings are more prominent, and they have attracted widespread attention in the industry and become the development direction of powder coatings.
The film-forming and curing temperatures of ordinary powder coatings are 180~220ºC, and the baking time is 15~25min. The curing time of HH2762 is 160ºC for 10-15 minutes. Compared with traditional high-temperature curing powder coatings, the film-forming temperature is lower, which can save a lot of energy. Some data show that every 10°C drop in the curing film-forming temperature of the coating can save about 10% of energy.

Company Profile:
Kinte Materials Science and Technology Co., Ltd. is subordinate to China Machinery Industry Corporation (a key state-owned enterprise directly managed by SASAC, ranking 284 among the world's top 500 in 2021). It is a national high-tech enterprise under China National Electric Apparatus Research Institute Co., Ltd. (Stock Code: 688128), a listed enterprise on the SSE STAR MARKET. Focusing on the R & D, production, and sales of environmentally friendly coatings (powder coatings, waterborne industrial coatings) and powder coating resins, the company is committed to improving the global market competitiveness of China's environmentally friendly coating industry. Now it has become the leader and promoter in China's technological development of environmentally friendly coatings as well as polyester resins for powder coatings!
We have gained ISO9001 and ISO14000, ISO18001, RoHS, UL certification, and QUALICOAT Certificates. Due to the excellent and stable quality, our products always enjoy a high reputation at home and overseas, and were sold to more than 30 countries.
The polyester resin branch was founded in 2000, now there are two factories (DongGuan factory and TaiXing Factory) with an annual production capacity of over 80,000 tons, and the annual production capacity reached 120000 tons by the end of 2020, opening the road to global diversified development. Our clients include many top-tier powder manufacturers in the world such as AKZO, PPG, TIGER, PROTECH, NIPPON, OXYPLAST, JOTUN, SHERWIN, VALSPAR, SINTERPLAST, etc.
We unremittingly stick to the business principle of "Quality is the life, adhere to first-class technology, first-class quality, first-class cost, and first-class brand". We would like to provide a complete set of services and solutions for both domestic and abroad customers and would like to go forward to a brilliant future with you together.
