Product Description
Excellent Flow 60/40 Polyester Epoxy Resin for Indoor Use Powder Coatings
HH2682 is a carboxyl polyester resin designed for 60/40 hybrid powder coatings.
Fast-curing polyester often helps in the following aspects in the use of powder coatings.
For example:
(1) Increase the crosslinking density, thereby improving the mechanical properties of the coating film such as hardness, cross-cut adhesion, and impact resistance;
(2) Reduce the curing temperature or shorten the curing time to achieve low-temperature curing or rapid curing;
(3) Hinder the melting and leveling of the powder, and achieve the control of the size of the texture and the appearance of the three-dimensional sense;
(4) Interfere with the slow or medium-speed curing system, and reduce the apparent gloss while leveling.

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.
