Why Is It Better To Paint With Powder Paint?

Painting With Powder Paint In Spokane

The powder, also known as electrostatic painting Powder Coating, is a system of industrial coating in Spokane dry powder that adheres to the parts forming a homogeneous color film. It was first developed in the US in the late 50s, but it was not until the early 60s when the extrusion system appeared to produce continuously since before the manufacture of these paintings was done by loads in kneaders.

Initially, the only method of applying powder paint was the fluidized bed, a technique that involves immersing the substrate to be painted, preheated or electrically charged, in a suspended powder bath with the inconvenience of presenting a high thickness of the film. This limited the application of these coatings to corrosion protection and electrical insulation, as they are expensive and not very decorative. To overcome these technological limitations, electrostatic guns appeared in 1962, which led to extraordinary growth in the application of powder paint on an industrial scale.

Its characteristics make it a very durable paint, with a perfect finish and a sustainable and very environmentally friendly paint, because it does not contain solvents or harmful components or contaminants, it also does not produce residue, since its surplus can be reused.

This type of manufacturing of powder coatings is done starting from a mixture of resin, hardener, pigment and additives that are milled to achieve their final appearance of powder paint.

Therefore, you can create all kinds of colours and finishes, such as the usual gloss, semi-gloss, matte, satin, textured, embossed …) and qualities.

For the application of electrostatic painting, three simple steps are required that can be automated:

  1. Treatment of the metal to be painted: degreasing of the piece and application of a phosphate layer (iron or zinc) by immersion or by manual lance.
  2. Painted: spray application of the powder paint that adheres to the metal electrostatically, in the parts generally grounded and conductive. This stage is carried out in a specific cabin that collects and controls the excess dust for reuse.
  3. Curing: baked at 180 degrees Celsius of the powder-coated piece, so that the paint polymerizes and acquires its final finish.

And it is that the powder paint has excellent adhesion and flexibility that allows even the folding, torsion and slow deformation of the pieces, has great resistance to abrasion, corrosion, chemicals and stains.

In addition, the powder paint has homogeneity of paint thickness with a higher quality appearance by rounded edges and is thermo-hardener, with resistance to extreme weather conditions, such as sun, ultraviolet rays, heat, cold and humidity.

Being manufactured and applied without the use of solvents, it does not emit toxic gases and produces a very low environmental impact, without VOC emission, the danger of flammability or the need for special safety measures for storage.

It does not need an anticorrosive base application, nor does it require mixtures or additives and its use is immediate without viscosity adjustments.

At the moment its use is habitual in finishing of metallic elements, furniture, railings, structures, aluminium profiles, toys, bicycles, tools, car bodies, etc. and being one of the cleanest and most efficient alternatives in the paint industry.
