⋅ Excellent adhesion, high chemical and thermal resistance and a favorable mechanical strength offer lasting protection against environmental influences and

   simplify cleaning.
⋅ Coating powders come in all RAL colors and a wide range of qualities such as special colors, glimmer effects, structures and special reflection values are

   possible.
⋅ Satisfy high functional standards for scratch resistance or chemical resistance. Different powders are used depending on the purpose.

 

Properties Of Powder Coatings

Epoxy Powder: High gloss surface, perfect bonding. Flexibility and chemical resistance, fine grain, closed, dense structure; thin layers are also possible. Not weather resistant; high decorative surface requirements are possible, for inside use.
Polyester Powder: Coarse-grained, less of a closed, dense structure; thick layers, weather-resistant, restricted fineness for decorative uses, for outside use. Chemical resistance is not as good as epoxy powder.
Mixed Powders: A compromise between epoxy and polyester powders. Weather resistance is more strength than epoxy powder.
Two-Layer Method: A bottom coating of epoxy powder followed by a polyester powder coating; very resistant, requires twice as much time and effort.

 

Zinc Phosphating

Coating powders require proper pretreatment, so, zinc phosphating yields the best corrosion protection, high-quality and is frequently used as a pretreatment before powder coating. The arising zinc phosphate layers approximately 7-15 µm thick are very effective in protecting steel from rust creep and in adition to this the zinc phosphate coating process can improve the appearance of finished goods through the creation of a uniform gray or black appearance.
