Powder coating additives must be stable in powder coatings for a long period of time in order to achieve their proper performance. Therefore, the commonly used additives should have good compatibility with epoxy, polyester, acrylic and other resins. Then the compatibility of furniture powder coating additives and resins is usually compared, and the method used is based on their structural similarity. For example, the use of leveling agents can be divided into one type is physical, and the other is carrier-free.

Carriers with E-12 as carriers cannot be used in the formulation of pure polyester systems. Furthermore, the commonly used B68 type chemical matting agent is only suitable for systems with epoxy, and for other systems, which not only loses its due effect, but also brings negative effects to the coating film.
