Product Description
60/40 Polyester Epoxy Resin with Excellent Leveling for Hybrid Powder Coatings
HH2686P is a carboxyl polyester resin designed for 60/40 hybrid powder coatings.
After years of development, powder coatings have made great progress, and their market shares and application fields have continued to expand. Amorphous polyester resins are currently mainly used in powder coatings. A remarkable feature of amorphous polyester resins is that there is a positive correlation between their glass transition temperature and melt viscosity, that is, the higher the viscosity, the higher the glass transition temperature. However, for powder coatings, polyester resins are expected to have a high glass transition temperature to ensure storage stability, and polyester resins are expected to have low melt viscosity, so that they have excellent flow properties. A coating with better wetting properties to pigments, resulting in better leveling properties.
The Tg of HH2686P is relatively low, and the melt viscosity is relatively low, so the powder coating prepared from it has excellent fluidity, and the polyester resin has better wetting performance for the pigment during curing, so as to obtain better leveling performance.

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.
