2K epoxy MIO primer and intermediate coat with lamellar barrier structure for aggressive environments. Engineered for shipbuilding, bridges & port machinery. Single airless spray pass achieves 60–80µm DFT.
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.

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