OKS 2511 is designed to restore permanent rust protection to damaged/scratched galvanised surfaces and for priming surfaces that cannot be galvanised for various reasons (cost/technical).
Rust/corrosion occurs mainly by chemical action or electro-chemical reaction. To achieve temporary corrosion protection up to 2 years (usually for storage and transport), oils and waxes are usually used, which are easy to apply and easy to remove. In cases where permanent corrosion protection for a period up to 10 years (and longer) is desired, other methods such as the choice of corrosion resistant materials, metal coatings (electroplating, metal spraying, hot dip galvanising), mineral coatings (enamelling, cementing), organic coatings (plastic coating or overlay) or electrochemical protection are used instead.
These choices must already be taken into account in the design and manufacturing phase.
To restore the surface and protection of galvanised surfaces that have been damaged during welding, drilling, or other processing, zinc spray is often used. Zinc spray is often used in maintenance and assembly sites, such as in the construction of steel structures, heating and pipework systems, and in the repair of exhaust systems and underbody protection of vehicles. Zinc spray is suitable for use after spot welding, for example. OKS 2511 has strong adhesion to ferrous metals and acts as a permanent rust inhibitor and is an excellent primer for many surface treatments.
Working temperature: up to +490°C
Salt spray test: 480 hours at 50 µm layer thickness
Coating thickness/layer: Approx. 20 µm/application
