Powder Coating, or Thermoset is a coating that, through a chemical reaction initiated by oven heating, forms a mechanically strong and durable film. Powder coatings are classified into groups based on their properties:
1. Epoxy (for indoor use, based on impact resistance)
2. Epoxy-Polyester (for interior elements)
3. Polyesters (weather-resistant, for outdoor use)
4. Polyurethanes (for parts intended for particularly harsh weather conditions)
We use powder coatings from Akzo Nobel (brand INTERPON), the world’s largest manufacturer of powder coatings.
Powder coating, i.e. thermoset, is a coating that, through a chemical reaction initiated by oven heating, forms a mechanically strong and durable film.
Epoxy, Interpon 100 series: Interpon 100 is a series of epoxy resin-based powder coatings designed to provide products and their components with optimal mechanical resistance and excellent protective properties in conditions where prolonged exposure to UV radiation and weathering is not expected.
Epoxy-Polyester Interpon 700 series: Interpon 700 is a series of epoxy resin/hybrid polyester-based powder coatings that offer superior color stability, heat resistance, and UV resistance compared to the pure epoxy resin-based Interpon 100 series.
Polyester Interpon TC series: Interpon TC is one of the most widely used TGIC-free* polyester-based powder coating series. TC offers high resistance to weathering and light.
Architectural grade polyesters Interpon D94 and Interpon D36: Interpon D94 (Interpon D94 HR Gloss) is a polyester coating with added weather resistance agents, representing a series of powder coatings for aluminum structures and galvanized steel. Available in a rich color palette, Interpon D94 is TGIC-free. As part of the facade powder coating series, Interpon D94 offers excellent weather resistance and color stability, and meets all basic European standards for structural coatings. All Interpon D94 colors fully comply with standards BS6496:1984, BS6497:1984, Qualicoat Class 1, and GSB.
Interpon D36 also meets all the aforementioned requirements and is available in a wide selection, including low gloss levels (30%).
Zinc-containing primer PZ 790, i.e. zinc primer: Powder zinc PZ 790/polyzink is a new type of zinc powder primer that has been tested in several parts of the world, including Sweden. Product PZ 790 is designed to protect steel surfaces, for example, to accelerate this process compared to hot-dip galvanizing. Therefore, both painting and zinc powder application take place in the same workshop with the same equipment. Tests conducted in Sweden confirmed that PZ 790 can be compared to steel treatment using the hot-dip galvanizing method. However, it should be noted that PZ 790 always requires a tinted powder coating as its topcoat. Tests also proved that PZ 790 is significantly better than a zinc phosphate plate that was coated with a wet primer and had a polyester powder coating as its topcoat. All tests conducted in Sweden used Interpon polyester powder coating type 12 688, approved by VCE (Volvo Construction Equipment).
For working with powder coatings, RAL, NCS, and RR color charts are used, with RAL being the most common.
Additionally, there are special effect colors, powder clear coats, textured coatings, etc.
