Product Description
TMA Free Polyester Epoxy Resin for 70/30 Hybrid Powder Coatings
HH2784 is a carboxyl polyester resin designed for 70/30 hybrid powder coatings.
As a kind of paint with zero VOC emission, powder coating has the characteristics of high efficiency, resource saving, environmental protection and excellent comprehensive performance. Compared with traditional solvent-based coatings, powder coatings have obvious advantages. In many fields, powder coatings are gradually replacing traditional solvent-based coatings. At present, powder coatings have been widely used in the decorative coating and protection of most metals such as furniture, home appliances, toys, automobiles, high-speed guardrails, and aluminum alloy windows.
Although powder coatings have environmental advantages, with the tightening of environmental regulations, some application fields with skin contact and food contact characteristics have also restricted the raw materials used. In recent years, there have been several non-industrial poisoning incidents related to chemical substances in coatings, which have attracted great attention from all parties. Relevant departments have also issued relevant restrictive laws and regulations. For example, the EU REACH regulations clearly limit the amount of organotin in powder coatings. content, I-KEA stipulates that tin should not be contained in polyester powder coatings for toys and furniture. On June 27, 2018, EU REACH officially issued a notice to include trimellitic anhydride (TMA) in the SVHC candidate list, and pointed out that TMA has respiratory sensitization. If the exposure time is prolonged and no intervention measures are taken, trimellitic anhydride will cause serious damage to lung function. permanent damage.
As the main raw material of polyester powder coating, polyester resin plays a decisive role in the health and environmental protection characteristics of powder coating. HH2784 does not contain TMA, which fully meets the environmental protection requirements of EU REACH.

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.
