Main highlights

No washing required: the protective film remains on the surface, therefore also suitable for cavities. Colour before use: white to slightly cream, after conversion: black
Effective rust conversion: reliably converts rust into stable, black iron complexes and creates a bonding bridge as a primer for further paint or filler work
Economical and environmentally friendly: 100 ml is enough for approx. 2 m² area (depending on the surface). Water based, heavy metal free, VOC free, store in a cool place (10-25°C), protect from frost and direct sunlight
Easy and safe to use: prepare the surface (remove loose rust, clean and grease-free), apply thinly and evenly with integrated brush. Wear gloves and goggles
Can be painted over and permanently protective: after approx. 6-8 hours air drying at 20°C and 50% relative humidity; overcoat is required for lasting protection (sample coat recommended)

Practical and safe: even in case of overdose, no attack on the metal due to the lack of stoichiometry effect. Temperature resistant up to 180°C. Processing at 15-25°C. 400ml aerosol can with dimethyl ether propellant gas storage stability up to 24 months at 5-25°C
Effective rust protection: Neutralises existing rust layers reliably stops further rust development and is ideal for aftertreatment of older rusty surfaces
