Product Description
Low Curing Powder Coating Polyester Resin for MDF Powder Coatings
HH2533 is a saturated polyester resin, which is mainly used for 50/50 polyester epoxy mixed powder coating, and can be realized low temperature curing at 130ºC.
Powder coatings have developed rapidly in recent years. Compared with traditional liquid coatings, powder coatings have the characteristics of energy saving, environmental protection and excellent comprehensive performance. With the strengthening of the concept of energy saving and environmental protection, the development of low-temperature curing polyester resin is a development trend. In addition, some heat-sensitive substrates (such as medium density fiberboard) are also sensitive to temperature and require low-temperature curing.
Reducing the curing temperature will inevitably require the resin to have high reactivity, and high reactivity will have a certain impact on the performance of the coating. The existing powder coating system mainly has the following problems when it is used for low temperature curing. On the one hand, the system reactivity is not enough, the powder coating cannot be completely cured, and the coating performance is not ideal; In order to achieve the reactivity required for low temperature curing, polyester resins often have high melt viscosity, high reactivity, and cannot be fully leveled under low temperature conditions. These all greatly affect the decorative properties of powder coatings.
HH2533 greatly improves the reactivity, and at the same time has good storage stability. When the resin is applied to powder coatings, it achieves low-temperature curing very well, the coating has good adhesion to the substrate, and has good leveling and stability. Chemical resistance, ideal for MDF powder coatings.

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.
