In February 2017, Guangdong Yajia New Energy-Saving Polymer Materials Co., Ltd., through the joint efforts of all employees, passed the rigorous layer-by-layer review and finally won the “Guangdong High-tech Products” issued by the “Guangdong High-tech Enterprise Association”. Certificates, there are two products that have been identified as high-tech products, namely “weather-resistant heavy-duty anti-corrosion powder coatings” and “easy-clean powder coatings”.

Weather resistant heavy anti-corrosion powder coating

Product features and uses:

The weather-resistant heavy-duty anticorrosive powder coating of the product adopts the hydrogenated bisphenol A epoxy resin of the repeating unit 3-5, and is cured by cross-linking film formation by using a polyamine under the action of a catalyst, has excellent weather resistance, and by adding a zinc-rich filler, With superior corrosion resistance. It is suitable for the coating of metal products with high requirements on corrosion resistance, heat and humidity resistance and weather resistance.

 Product technical advantages:

     (1) Good weatherability: using hydrogenated bisphenol A epoxy resin of repeating unit 3-5, curing and cross-linking film formation by using a polyamine under the action of a catalyst, compared with ordinary bisphenol A epoxy resin benzene ring powder coating , with excellent weather resistance;

      (2) Good anti-corrosion: Adding zinc-rich filler, after using high-purity zinc powder which is melted and processed to purify fine particles, its electrochemical activity (the standard electrode potential is -0.76V) is more active than iron (-0.44V). When it is corroded with iron, the steel is protected by the effect of “self-sacrifice” and has super anti-corrosion effect;

      (3) Fast curing speed: the modified aliphatic amine curing agent is used, because the reaction is slow at normal temperature, and the modified imidazole is used for catalytic curing to achieve the goal of rapid curing, in order to improve the cleanliness of the hydrogenated bisphenol A epoxy resin, Abandon the shortcomings of high residual chlorine in general washing method (high residual chlorine is a fatal defect for heavy anti-corrosion coating), it can be quickly cured by medium frequency heating, or it can be heated and cured by ordinary oven.

Easy clean powder coating

Product features and uses:

This product easy-clean powder coating is made of special resin as the main raw material. It has excellent chemical resistance, surface hardness and wear resistance. The surface of the coating is not easy to stick to oil stains and stains. At the same time, the product is added with nanoparticles, has good acid and alkali resistance, scratch resistance, and is suitable for the coating of metal products which are resistant to chemicals and used in places where the surface is easy to be graffiti.

 Product technical advantages:

      (1) Oil-resistant and easy to clean: Add silicon-containing monomer, fluorine-containing monomer and ester monomer, and polymerize into block copolymer to make the coating have low surface energy, which can be easily cleaned after spraying on the surface of metal material. The coating effectively reduces the adhesion of the oil to achieve an easy cleaning effect;

      (2) Acid and alkali resistance, scratch resistance: Adding nanoparticles to make the coating have good acid and alkali resistance and scratch resistance. Even with high hardness cleaning tools such as detergent and steel ball, it can protect metal materials from being damaged. Corrosion, scratching, can pass 1000 hours 5% acid salt spray test, the coating corrosion rust distance is less than 2mm;

      (3) Good adhesion: This product uses nano-particles as the core and block copolymer as the shell microstructure material, which greatly improves the adhesion between the coating and the metal substrate.

        The awards of these two high-tech products have raised higher and farther requirements for the development of our company. The company will continue to adhere to technological innovation and service innovation, keep moving forward, and strive to achieve greater breakthroughs while promoting the company's development. The national powder coating industry has made greater contributions.
