Strong adhesion, simple construction, short surface drying time, good adhesion with various types of coatings after treatment, can be applied to a variety of different process requirements. Excellent compatibility, compatible with almost all coating systems. It can be added to paint systems without affecting their storage stability and does not affect the weatherability of the paint film. Improves ductility and impact resistance, promotes cross-linking and curing of resin systems, and puts off silver.
Brightener ZS-302 is an improved and improved additive based on ZS-301 and ZS-310. It can produce a protective film on the surface of the coating film, improve the surface clarity and scratch resistance, and the coating film gloss (60° ) It can reach more than 199%. It is used for powder coatings with copper and gold powder and aluminum powder. The amount is 2% to 3% of the total formula, and it is dispersed by melt extrusion mixing method. The brighteners HW301 and HW302 of Hangzhou Hongwei Chemical Industry and Trade Co., Ltd. have the same effect as the brighteners ZS-301 and ZS-302 of Hangzhou Zhongshun Chemical Industry and Trade Co., Ltd. Hubei Hongtu Chemical Products Co., Ltd.’s high-energy brightener 771, the dosage is 0.8% to 1.5% of the total formula (the dosage is 1.5% to 2.5% during dry mixing), and it is dispersed by melt extrusion mixing method or dry mixing method. Aluminum powder, copper gold powder, pearl powder and nickel powder.
The effect of metal powder dispersant and aluminum powder brightener is similar, and there is no strict difference between each other. It mainly improves the dispersion of metal powder in powder coating to make the coating film of metal powder powder coating metallic glitter and metallic luster. It is more beautiful and colorful, and gets a better decorative effect. At the same time, a protective film is formed on the surface of the coating film, which is not easy to pollute the metallic glitter and metallic luster, keeps it longer, and is not easy to scratch, and provides better protection Effect.
In addition to the dispersant and brightener of metal powder, there are also additives such as aluminum powder deprinting agent and aluminum powder hardening agent. Aluminum powder deprinting agent is to eliminate the fingerprints of the aluminum powder coating film, change the surface tension of the coating, improve the surface clarity of the coating film, increase the surface smoothness and scratch resistance, and improve the chemical resistance and high temperature resistance. If you add Aluminum powder hardener or micro-powder wax, the effect is better. Guangzhou Tianlong Chemical Co., Ltd.’s anti-printing hardener AS501, the dosage is 0.3%~0.7% of the total formula, and it is dispersed by melt extrusion mixing method. The aluminum powder deprinting agent ZS602 of Hangzhou Zhongshun Chemical Industry and Trade Co., Ltd., the dosage is 1.2%~2% of the total formula, and is dispersed by melt extrusion mixing method.
