powder coating elements

Many varieties of powder coating, different formulations, but its basic components usually include resin, curing agent, a variety of additives and pigments. A typical powder coating formulation should contain a 1,50%-60% base material (including resin and curing agent); 2,30%-50% pigments and fillers; 3,2%-5% leveling agents and other additives. Usually, resin refers to has a relatively high molecular weight and low functional polymer, thermoplastic and thermosetting; Department of curing agent refers to with low relative molecular mass and officials to the oligomers and compounds.

Powder coating pigments and fillers and solvent based coating is basically the same; additives including curing agent, leveling agent, brightening agent, flatting agent, art type additives, edge covering agent, anti caking agent, light stabilizer and so on. Electrostatic powder coating is the coating in under the action of high voltage electrostatic induction charged, under the action of electric field force the powder coating (spray powder / baking powder) uniformly absorbed on the surface of the coated workpiece, again through the melt flow flat and curing film to achieve the purpose of coating as a method. In the process of painting will produce a large number of non adsorbed powder, the powder will cause pollution to the surrounding air.
