Technical information The 3-phase coating procedure Coating procedure Technical properties Technical specifications Degreasing, nanoceramic pretreatment, rinsing Used as corrosion protection and to improve paint adhesion. Nanoceramic conversion layer Anodic dipcoat priming Even layer formation on all surfaces, edges and in cavities, which produces a high level of corrosion protection even at the assembly stage. The primer is readily overpainted and free from heavy metals, chromate and silicone. Stove enamelling Textured powder-coating Powder-coating is distinguished by a high level of mechanical resistance, excellent corrosion protection, good resistance to chemicals and temperature, and its facility for decontamination. The powder coating is readily overpainted and is free from heavy metals, chromate and silicone. Stove enamelling The coating is resistant to: ◾ Mineral oils ◾ Lubricants ◾ Machine emulsions ◾ Alcohol-based solvents (briefly, e.g. during cleaning) ◾ Weak acids and alkalines Primer or powder coating suitable for overpainting After careful cleaning of the surface, the standard coating may be overpainted with: ◾ DD gloss paints ◾ Single and dual-component gloss paints ◾ Car repair paints ◾ Powder paints ◾ Water-based paints Erichsen cupping test to DIN EN ISO 1520 ≥ 4 mm Buchholz hardness to DIN EN ISO 2815 ≥ 80 Cross cutting to DIN EN ISO 2409 Gt 0 Erichsen cupping test to DIN EN ISO 1520 ≥ 3.5 mm Buchholz hardness to DIN EN ISO 2815 ≥ 80 Cross cutting to DIN EN ISO 2409 Gt 0 Salt spray test to DIN EN ISO 9227 NSS Test period: 168 hrs Condensate test to DIN EN ISO 6270-2 CH Test period: 500 hrs Condensate test to DIN EN ISO 6270-2 AHT Test period: 20 cycles If in doubt, perform a compatibility test. Always follow the paint manufacturer’s instructions. When overpainting, take care not to exceed 180°C and a baking time of 15 minutes. Outdoor use of enclosures In order to guarantee satisfactory long-term function of enclosures in outdoor use, the relevant environmental factors must be taken into account. These include: ◾ UV radiation, the corrosive action of air pollution, rain, icing, snow, wind or other factors in special climatic conditions. Condensation inside the enclosure Condensation must be prevented by means of appropriate measures, e.g. by venting or heating the enclosure. Protection category The enclosure may be exposed to extreme weather conditions during outdoor use. Long periods of rain, snow, ice, high winds and temperature fluctuations place particularly high demands on the enclosure sealing. The protection category IP X3 as envisaged for external weather conditions in DIN VDE 0100, part 737, point 5.2 is often insufficient to provide permanent protection for electrical equipment. 722 Rittal Catalogue 34/Technical Information
