Récent 47++ Powder Coating Pretreatment Process
Récent 47++ Powder Coating Pretreatment Process. For high end applications, zinc phosphate may be the pretreatment of choice. In short, they are the processes through which a surface is cleaned and prepared to be coated. Most powder coatings have a particle size in the range of 2 to 50 μ (microns), a softening temperature tg around 80 °c, a melting temperature. With this technology we can monitor the usage of materials and chemicals in future.
