The process of manufacturing powder coatings is a relatively complex process that must be carefully controlled to ensure a high-quality final product. Powder coatings are manufactured in a multi-step process of pre-mixing, extrusion, and micronization. Basically, materials are blended, melted, cooled, and then pulverized. This blog will focus on pre-mixing, the first step in the process.
Pre-mixing: this involves the weighing and mixing of all the raw materials, which includes resins, curing agents, pigments, and additives.
