DESCRIPTION
High gloss powder coating is a solvent-free powder-based type of coating used commonly to coat metals for a wide range of applications, such as in automotive industry. The surface appearance can be generally tuned by the addition of external additives to the powder formulation. High gloss powder coating has important advantages over liquid-based paints: being ease of application, high utilization by electrostatic spraying, environmentally friendly since they do not contain organic solvents, and showing excellent performance once applied. These properties allow powder coatings to be used in a wide variety of applications, i.e. automotive, architectural, electronics and furniture amongst others. A powder coating is composed of a resin, a catalyst, a cross-linker, pigments and additives such as flow modifiers and degassing agents, which define the properties of the final powder coating, including the surface finish (glossy or matte).
High gloss powder coating reflects the entire incident light in a mirror-like fashion, whereas a matte finish scatters part of the light, reducing the gloss level. The difference in gloss or matte appearance relies on the surface texture, whether it is highly smooth or it presents some roughness. Certain indoor applications require glossy paints, while for industrial and agricultural purposes. A matte paint is preferred to hide surface irregularities and damages. The gloss level of a powder coating can be reduced by the addition of a foreign compound, such as inorganic fillers or rheological additives that can have different reactivity or curing temperature than the powder, by varying the size of the powder coating particles, by varying the humidity of the environment or by tuning the conditions during electrospraying. Here we present a novel approach for gloss reduction that avoids the addition of foreign particles to the powder formulation, which may induce segregation or non-uniformities in the final product, but just relies on the surface modification of the primary powder coating particles to induce a transition in the surface appearance of the paint.
ADVANTAGES
We use the better resin
Much higher first pass rate
Better hardness
Better abrasion resistance,flexibility
Better chemical resistance
