Penguard Express MIO

Penguard Express MIO is reinforced with Micaceous Iron Oxide pigments for increased barrier effect.

This barrier effect is provided by overlapping layers of the MIO pigments which prevent moisture penetrating through the paint film. It further provides increased hardness and improved adhesion of subsequent coats.

Product Description

Penguard Express MIO is a fast drying, high solids two pack micaceous iron oxide pigmented epoxy coating which may be applied in high film thickness and at lower temperatures.

It is recommended for use as an anti-corrosive primer and/or intermediate coating for corrosion protection of steel and other substrates in atmospheric exposure where fast dry-to-recoat and/or dry-to-handle times are desired.Penguard Express MIO can be used alone or in various systems of primers and topcoats.

Drying times are generally related to air circulation, temperature, film thickness and number of coats, and will be affected correspondingly. The figures given below are typical with

  • good ventilation (Outdoor exposure or free circulation of air)
  • Typical film thickness
  • One coat on top of inert substrate
Substrate Temp -5°C 0°C 5°C 10°C 23°C 40°C
Surface dry 16h 11h 4h 2h 1h 0.5h

Dry to recoat minimum 24h 14h 8h 4h 2h 1h

¹ Provided the surface is free from chalking and other contamination prior to application, there is normally no overcoating time limit. Best intercoat adhesion occurs, however, when the subsequent coat is applied before preceding coat has cured. If the coating has been exposed to direct sunlight for some time, special attention must be paid to surface cleaning and mattening/removal of the surface layer in order to obtain good adhesion.


The given data must be considered as guidelines only. The actual drying tim before recoating may be shorter or longer depending on film thickness, ventilation, humidity, underlying paint system, requirement for early handling and mechanical strength etc.
