SigmaDur 520 MIO Polyurethane Finish

SigmaDur 520 MIO, the micaceous iron oxide version. The flake pigment lies in overlapping layers inside the film and lengthens the path moisture must travel to reach the steel, which is why MIO coats are specified on exposed structural work.

• Check before ordering: Stir thoroughly and keep stirring during use — the heavy flake settles out and takes the protection with it.
