OKS 2561 - Zinc-Aluminium Protection, Spray

Areas of application

For touching up damaged spots on galvanised surfaces, e.g. after welding, drilling or cutting without a subsequent paint finish
For protecting metal surfaces such as gratings, fences, gutters and similar.

Advantages and benefits

Enduring corrosion protection with active cathodic corrosion protection thanks to optimum combination between zinc and aluminium pigments
Colour tone resembles that of a hot-dip galvanized surface, allowing for touch-ups in a single application
Self-healing polymer layer which closes again after slight damage and prevents corrosion
Suitable for corrosion protection up to Category C4H as per EN ISO 12944:2018-06 for areas with an industrial atmosphere and coastal areas with moderate salt levels

Applications

Clean the surfaces for optimum adhesion. It is best to clean mechanically first and then with OKS 2610 or OKS 2611 universal cleaner. The surface to be treated must be dry, uncoated and free of grease. Shake the can before use until you can hear the stirring balls rattle and continue shaking vigorously for 2 more minutes. Optimal layer thickness: Spray evenly onto the prepared surface from a distance of 20 - 30 cm using 3 - 4 cross coats or circular movements. Avoid local excesses. For thicker layers, apply another coat after the solvent has evaporated. After spraying, turn the can upside down and spray the valve in this position until only solvent comes out. Drying and curing times as per following technical data.
