PLH53-3 Epoxy Micaceous Iron Oxide (MIO) Anti-Rust Intermediate Coating

Overview

PLH53-3 Epoxy Micaceous Iron Oxide (MIO) Anti-Rust Intermediate Coating is a two-component epoxy MIO anti-rust coating/intermediate coating providing barrier protection; the anti-rust pigment forms a “fish-scale” overlapping structure after film formation.

The product is formulated with epoxy resin, micaceous iron oxide powder, anti-settling agent, anti-rust agent, fillers, and solvents, and is supplied with a polyamide curing agent as Part A and Part B. It can be used as a long-term anti-corrosion primer and as a reinforcing coat over zinc-rich primers or thermal sprayed zinc layers to improve sealing and corrosion resistance.

Key Benefits

• Provides barrier protection in anti-corrosion coating systems

• Can be used as a reinforcing coat over zinc-rich primers

• Can be used over thermal sprayed zinc layers to improve sealing and corrosion resistance

• Can be applied by airless spray, brush, or roller

• Compatible with a range of topcoat systems

Recommended Uses

This intermediate coating is suitable for a wide range of steel protection projects in industrial and marine environments.

Typical application areas

• Ships

• Containers

• Bridges

• Steel gates

• Gas holders

• Port machinery

• Various steel structures

Maintenance and repair uses

• Used with zinc-rich primers to enhance sealing and corrosion resistance

• Used over thermal sprayed zinc layers to improve sealing and corrosion resistance

Application Guide

Surface Preparation

When applied over a two-component primer, all surfaces must be clean, dry, and free of contaminants; if the maximum recoat interval is exceeded, surface roughening is required. If used directly as the first coat, abrasive blasting to Sa 2.5 or power-tool cleaning to St 3 is required; surface profile 30–75 µm.

Technical Data

Storage
Store in a dry, cool, ventilated warehouse away from fire sources and direct sunlight; outdoor storage is not permitted.

System Compatibility

This intermediate coating is compatible with epoxy topcoat, polyurethane topcoat, acrylic topcoat, chlorinated rubber topcoat, high chlorinated polyethylene topcoat, chlorosulfonated polyethylene topcoat, and chlorinated ether topcoat.
