Product Description
93:7 Saturated Polyester Resin with Excellent Leveling for TGIC Powder Coatings
NH3309T is a saturated polyester resin, mainly used in polyester/TGIC powder coating systems, with excellent leveling. It can also be used with acrylic matting resin or other physical matting agents to make low-gloss or matt coatings with good results.
Models with a T indicate powder coatings made with this polyester resin that can be sprayed with a friction gun.
At present, the common powder coating spraying processes are electrostatic spraying and friction gun spraying. Electrostatic spraying is widely used in China because of its low requirements for powder coatings. However, due to the Faraday cage (shielding) effect, there will be dead corners on complex workpieces, and some corners are difficult to powder.
Although the electrostatic gun has been improved many times, the Faraday cage effect can only be reduced, but cannot be avoided. The friction gun spraying can well solve the problem of powder coating in the dead corner of complex workpieces, but it also puts forward higher requirements for the electrification of powder coatings.
The working principle of the friction gun is to use frictional electrification to charge the powder. The charge is generated by the collision, friction, contact, and clutching between the powder and the special polymer material and nylon in the gun wall. The driving force is the airflow.
NH3309T is a friction-type polyester resin, which has a very good effect on frictional electrification. It is used by customers at home and abroad, and the effect is very ideal.

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.
