Powder Coating

The overwhelming success of any paint powder depends on equipment measurements, the nature of the powder, its composition and its condition.

There is a variety of powder, which can choose from, the final selection will depend on the final use requirements of the coated surface.

In thermoplastic systems, the polymer is usually a molecular weight, low melting, flowing during fusion, and immediately passes any chemical transformation to any processed or coherent heat. Once connected to this condition, it can not be repositioned to any plastic case. As is the case with thermoplastics.

The solidification reaction, in the thermocouple powder, occurs between the specialized (reactive) metal parts of the resins and the special metal parts of the processing agent. It is obvious that, to obtain a smooth layer, the polymer must be transformed into a soft layer, before the process begins.

The powder is a harmonious component, where the temperature of the lining is balanced, with the properties of viscosity, fusion, and speed of hardening. As with solvent-based coatings, heat-tight powder can be installed to produce decorative coatings, special effects of aluminum, bronze, metalic, distinctive texture, and strong, low-gloss effects and finishes.

 

Epoxy powder

This powder can be installed to provide soft, high gloss, cohesive, flexible, and excellent chemical resistance. The main drawback is the yellow bias at high temperatures or when exposed to daylight. In addition, this powder quickly converts to chalk, on external surfaces, however, the safety of the coating layer on the outside surfaces is excellent. Treatment of epoxy powder is an additional mechanism, and no volatile substances are present, emitted during heating.

 

Polyester powder

This powder has excellent external bearing strength, accompanied by high resistance to yellowing under the influence of ultraviolet light, and should be heated for long periods and at high temperatures, compared to epoxy powder. Polyester powder resistance to chemical agents is just below powder.

 

Powder polyester and epoxy mixture

This powder, a class of solid powder, is widely used. Epoxy resin is a catalyst for polyester resins. Based on the selection of resin and its proportions, the properties of the mixture powder are combined between pure epoxy and pure polyester. The presence of this type of epoxy resins, resins are subject to alteration, on external surfaces.

 

Polyurethane powder

Polyurethane powder contains powder properties, which contain hydroxy, which interact with the covered (or retained) isocyanates. This powder provides a complete chemical and physical properties, as well as good external bearing strength.
