Product description:
RustConverter is based on water-dilutable acrylic dispersions and tannin.

Product properties and use:
RustConverter is a primer to be used directly on rusty surfaces of iron and iron alloys. RustConverter chemically connects with rust and creates a black, stable surface more resistant to moisture. It protects the surface against further corrosion.

RustConverter must be coated subsequently.

100 µm

The practical spreading rate depends on application method, form and surface of the material.

Remove all loose rust with a stiff brush, hammer or the like, and clean the surface from grease and other contamination, preferably using high-pressure and Iso A-Clean.

The primer must be stirred before use.

Always to be used undiluted

Application temperature:
The temperature must be between 8° C and 30° C and 85 % RH.

Application method:
Brush, roller, or airless, nozzle sizes 19-21, 180-200 bar

Often, one treatment will suffice, but sometimes several layers are necessary to ensure that the area is totally covered.

Always make a test coat to ensure the compatibility of product and surface.

RustConverter must be coated with Metal Primer WB, Isoxyde, or Metal OneCoat to obtain corrosion protection.

Drying time:
Laboratory tests

 Wet layer thickness 100 µm
