Micaceous Iron Oxide

Synonyms:

Micaceous hematite, Natural lamellar hematite, Specular iron oxide, Micaceous iron oxide,

Natural specular hematite ore

Designations:

Chemical Name: Micaceous iron oxide

Chemical Formula: Crystalline Fe203

Description:

1) A naturally occurring lamellar form of ferrous oxide for use in manufacturing paint coatings.

2) When viewed under an optical microscope by transmitted light, magnification X 200, the thin

flake micaceous iron oxide particles appear as sharply defined red translucent platelets.

3) Without doubt, it is the most important barrier pigment used in coatings to protect structural

steelwork from corrosion. It has a 100 year record of successful use on many types of steel

structures throughout the world.

4) It forms overlapping plates like mail armor. It reflects ultaviolet light, allows water vapor to

escape from the substrate, and is chemically resistant.

Typical Applications:

Bridge structural protective coatings, oil rig structural protective coatings, and protective

coatings for all types of electrical and industrial equipment where durability and reliability are

important.

It has been successfully used in various paint primers with single or multiple top coats in alkyd,

epoxy, vinyl, acrylic, polyurethane, and chlorinated rubber.

It has been used in corrosion and weather resistant paint throughout Europe for more than 100

years. The Eiffel Tower is one outstanding example.

The horizontal layering of the lamellar (micaceous) particles, overlapping like scales on a fish,

gives strength to the paint and acts as an inert barrier to the vertical penetration of corrosive

elements and ultraviolet light.
