Despite the size of agricultural machinery and construction equipment (including forklifts, trailers, trucks, forrest, snow, mining equipment and machinery) as well as the parts of equipment being coated, the powder coating process can be carried out in an industrial environment by assembling several components in advance. With the composite construction often found in this industry, a broad range of parts made of substrates such as aluminum, steel and galvanized steel are used. Depending on the equipment end use, PoosheshFam polyester-based powder coatings are recommended for aluminum substrates. For steel parts; threatened by corrosion, a two-coat system is recommended (the system comprises a corrosion-protecting powder primer and a polyester powder top coat). The application of fillers for the removal of substrate defects can generally be relinquished with the use of powder coatings. Due to the high coating thickness achieved compared to liquid top coats, coverage is significantly better. Optimal quality characteristics, in particular the high mechanical resistance and excellent edge protection, can be realized by applying even a single-coat system.
