JOTUN PENGUARD HSP MIO

Jotun Penguard HSP MIO is a fast-drying, high-build epoxy coating with active zinc phosphate.

Jotun Penguard HSP MIO is a fast-drying, high-build epoxy coating designed for new construction. This high-solids product can function as a primer, midcoat, finish coat, or as a single-coat system in atmospheric conditions. Reinforced with micaceous iron oxide (MIO) pigments, it delivers an enhanced barrier effect for superior protection.

Penguard HSP MIO offers very fast dry-to-recoat and dry-to-handle times, improving application efficiency. It is suitable for use on properly prepared aluminium, carbon steel, galvanised steel, shop-primed steel, and stainless steel substrates. The coating can be applied at temperatures as low as 0 °C, allowing greater flexibility during application.

Here’s why MIO is important in coatings like Penguard HSP MIO:

Flake structure: The tiny, flat flakes of MIO align parallel to the substrate when applied, forming a dense, layered barrier. This structure makes it harder for water, oxygen, and other corrosive agents to penetrate the coating and reach the surface.

Enhanced durability: Coatings with MIO exhibit greater resistance to UV radiation, chemical exposure, abrasion, and mechanical damage compared to coatings without it.

Longer service life: Thanks to the improved barrier effect, MIO-containing coatings are commonly chosen for harsh environments — like offshore structures, bridges, refineries, and power plants — where long-term corrosion protection is critical.

Visual effect: MIO also gives coatings a distinctive metallic or matte grey appearance, which is often associated with industrial strength and durability.
