A two-component epoxy anti-rust paint composed of epoxy resin, polyamide resin hardener, grey mica iron oxide, anti-rust pigments, additives and
solvents.
Excellent adhesion on properly prepared galvanized steel and aluminium alloys
Excellent adhesion and sealing on zinc-rich primers and zinc-sprayed steel
Good weather resistance and corrosion resistance in industrial and chemical atmospheric environments
The surface has a certain roughness, with very good compatibility with epoxy, chlorinated rubber and polyurethane topcoats
and can also be used with traditional coatings such as alkyd and phenolic, with good intercoat adhesion to subsequent films
Can be used as an intermediate coat for high-performance anti-rust paints such as epoxy zinc-rich primers and inorganic zinc primers to enhance
the intercoat adhesion and protective performance of the whole coating; can be used on galvanized steel and aluminium alloy surfaces as
a primer; can also be applied directly on blast-cleaned steel surfaces as an anti-rust primer. Widely
used in heavy anti-corrosion systems for ships and onshore steel structures.

Steel coated with zinc-rich primer: remove all oil, debris and zinc salts
Galvanized steel: grind with pneumatic or electric flexible abrasive discs to remove all oil, debris and zinc
salts; if used for underwater areas, sweep blasting must be used for surface preparation
Steel coated with shop primer: secondary rust removal on damaged film, rusted areas and white rust on zinc-containing primer; remove white rust and grind to St 3
Aluminium alloy: sweep blast to roughen the hull bottom areas, sandpaper to roughen waterline or onshore areas
Compatible old paint film: after removing all oil and debris, roughen the old film
For outdoor application at substrate temperatures below 5 °C, use winter-type 842 Epoxy MIO Anti-rust Paint

842 Epoxy MIO Anti-rust Paint can be applied at air temperatures between 5 and 10 °C, but the curing speed is very slow
Below 5 °C, application is not advisable because the reaction between the epoxy resin and the curing agent stops. At
In this case, application can be carried out in a coating workshop above 5 °C. Or use 842 (winter type) Epoxy MIO Anti-rust Paint
Adequate ventilation is required during the application and curing of 842 Epoxy MIO Anti-rust Paint
842 Epoxy MIO Anti-rust Paint generally has no maximum overcoating interval when the film surface has not chalked
or been contaminated by other substances. However, better intercoat adhesion is obtained by applying the next coat before the film is fully cured
If the film of 842 Epoxy MIO Anti-rust Paint is exposed to the atmospheric
environment for a long time before applying the next coat, special attention should be paid to cleaning the film surface
and removing the chalking layer by abrading to obtain good adhesion
If the film thickness of 842 is excessive during application, or the relative humidity exceeds 85% during application,
the film will show a smooth surface. Before applying the next topcoat, it must be abraded with sandpaper to increase intercoat adhesion
