Haematite Intense Tinting 100gr

Haematite is a micronized, natural iron oxide pigment that provides a highly intense coloring effect. When used in corrosion-protective paints, haematite absorbs UV rays, effectively safeguarding the binding agent.

The following effects are reached:

- an excellent corrosion protection

- a good dispersibility

Typical fields of application:

- Corrosion-protective paints

- Priming coat

- Varnishes

- Building material

Haematite can be used in systems which contain solvents as well as those which are solvent free and in

aqueous systems.
