Resin
Powder coating contains resin at all times. The two most prevalent types of resin are epoxy and polyester. Either type is present in the coating.
Additives
Powder coating Additives are another crucial component of powder coating. There are numerous additives present, each providing a particular purpose. Some of these additives are used to provide a harder finish, while others produce a matting finish. The most well-known addition provided in Dongyuan is benzoin, which is added to epoxy resin and reduces surface tension as well as melt viscosity. Other types of additives are as follows.
post Additives
Post additives are also an important component with additives because they prevent the powder from caking, yellowing, oxidant, and scratching effects. effects They are added after the powder has hardened and been broken up into little fragments.
Curing agent
Curing agents are used to increase the coating's longevity and solidify it. They can bond the covering usually post beyond Additives. When epoxies are included in the coating, dicyandiamide curing agents are utilized, while primed curing agents are used when polyesters are present. Sometimes, hybrid curing agents are utilized. Both dicyandiamide and primed curing agents are present in hybrid curing agents.
Pigments for coloring
Powder coating also contains tint pigments. They bring the color of the coating to life. The first type of pigment is inorganic, and the colors in this category are typically dull and pale. Organic colors are more brilliant than inorganic pigments.
Fillers
Fillers, also known as Extenders, offer an extra layer of resilience to the coating. They also help to minimize glossiness used as the biggest support for Additives to improve it is featured in the final product of paint.
