The product is mainly used to enhance the adhesion between ABS, TPU, PS, PC polycarbonate, BOPA biaxially oriented nylon film, BOPET biaxially oriented polyester film, BOPP biaxially oriented polypropylene film, BOPI polyimide film, BOPS biaxially oriented polystyrene, BOPE biaxially oriented polyethylene film and other plastic workpieces and paint.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The advantages of epoxy ester plasticizers are that the coating film has good heat resistance and light resistance, is not easy to yellow, has good compatibility with resins, has good wetting properties, is non-toxic, and can be used for plasticizing food contact materials , The disadvantage is high price, the advantage of chlorinated hydrocarbon plasticizer is that it has excellent acid resistance, alkali resistance, water resistance and flame retardancy.

The use of plasticizers will improve the hardness and brittleness of powder coatings, and can impart some new properties to the coating film, such as flame retardancy, aging resistance, flexibility, impact resistance and elongation. In order to give full play to the role of plasticizers, it is necessary to go through necessary application tests, select appropriate varieties and dosages, and use different types of plasticizers in combination, which is more conducive to complementary advantages or synergistic effects. Generally, plasticizers are used more in thermoplastic powder coatings, but rarely used in thermosetting powder coatings. The addition amount in the formula is 1% to 25%, and it is dispersed by melt extrusion mixing method.

Toughening agent is an additive added to improve the toughness of the coating film. Tougheners also require good chemical stability, do not react chemically with resins, curing agents, pigments, fillers and additives in powder coatings, have good thermal stability, and require good compatibility with resins, which can be obvious after adding Change the mechanical properties of the coating film such as flexibility, bending resistance and impact resistance. Many low molecular weight thermoplastic resins can be used as toughening agents, such as polyvinyl butyral, cellulose acetate butyrate, micronized olefin wax, etc. The addition amount in thermosetting powder coatings is 1% to 5% of the total formula , Guangzhou Tianlong Chemical Co., Ltd. Toughener TL600, the dosage is 1%~3% of the total formula. After adding, it can enhance the bending resistance, adhesion, impact strength and flexibility of the coating film, and can increase the amount of filler. The leveling function improves the loose state of the powder coating. It is also a coating film corner coverage modifier, which can prevent the coating film from sagging and shrinking.
