powder coating no voc

The reason for the coating particles produced in powder coating in the gel, causing insoluble particles and impurities. Fine particles of powder coatings in easy accumulation change the site of airflow direction in the coating device and spray head or in the pipeline, when accumulated to a certain degree the state of aggregation spray out attachment is painted above, baking does not melt and become diameter for 0.5-3 degree of particles attached in the spraying chamber wall and recycling equipment gelatinizer: manufacturing powder coating process due to a pigment produced 

condensates. This kind of light stabilizer can capture the active free radicals generated in the polymer, which can inhibit the oxidation process and achieve the aim of light stability. When the powder coating to absorb ultraviolet energy and decompose to produce lead to auto oxidation reactions of reactive free radicals, free radical capture agent can capture the free radicals, and the chemical reaction to change for stable macromolecular compounds, so that the photo oxidation reaction termination. As long as the powder coating is sprayed to after suitable treatment of steel or aluminum, the excellent performance of the coating surface is obtained by baking can be, such as the persistence of the film, including: wear-resistant rub, impact resistance, sealing, 

toughness, corrosion resistance and resistance to chemical properties and so on.

And powder coatings for outdoor use, in addition to the above advantages, including the high weather resistance and pollution resistance. In particular, a thick coating, powder coating can be achieved at a time of 50-300 mu m, and the leveling of the good, not as solvent coating thick coating will have a drop or the accumulation of stagnation and other phenomena occur. Powder coating without the use of volatile organic solvents and water solvent, so powder coating is a kind of inorganic solvent based paint, greatly reducing the potential safety problems caused 

by the solvent, such as because of containing organic solvent caused by operating personnel organic solvent poisoning or because of fires caused by organic solvent. From the last century 

five, 60s powder coatings available so far, there has not been a major security incidents caused by powder coatings. Part of the resin curing reaction gel particles in the melt mixing process, the particles will form a coating on the particles. In the construction of electrostatic spraying, the problem of environmental dust should be paid enough attention. Dust from the air, peeling off the operating personnel work tape bag recycling equipment on the fiber and curing equipment, the dust in electrostatic powder spraying process will cause film pollution and particles.
