Epoxy Micaceous Iron Oxide Coating
Overview
Epoxy Micaceous Iron Oxide Coating is a two-component intermediate coating designed to provide durable barrier protection for steel and other substrates. Its lamellar micaceous iron oxide structure helps block moisture penetration while providing high impact resistance, flexibility, water resistance, and strong intercoat adhesion.
Introduction
Epoxy Micaceous Iron Oxide Coating is a two-component coating based on epoxy resin, lamellar micaceous iron oxide, and polyamide curing technology. It is primarily used as an intermediate coat over zinc-rich epoxy primers, inorganic zinc-rich primers, or epoxy anti-corrosive primers, and can also be used as a primer on galvanized or blast-cleaned steel.
Its lamellar structure provides effective barrier protection against moisture penetration, while the cured coating offers good impact resistance, flexibility, and water resistance. The coating also provides strong intercoat adhesion with epoxy, polyurethane, chlorinated rubber, alkyd, and fluorocarbon coating systems, allowing it to be incorporated into a range of protective coating systems.
Features
Excellent Barrier Protection
The lamellar micaceous iron oxide structure provides an effective barrier against moisture penetration, helping protect the underlying substrate.
High Impact Resistance
The cured coating provides high impact resistance, supporting durable protection against mechanical exposure.
Good Flexibility
The coating film provides good flexibility, helping maintain coating integrity under service conditions.
Water Resistance
The coating demonstrates good resistance to water and salt-water exposure. After 30 days in 5% sodium chloride solution at 25°C, there was no blistering or loss, with only slight color change permitted.
Salt Spray Resistance
The coating demonstrated 1,000 hours of salt spray resistance with no blistering, loss, or rust.
Strong Intercoat Adhesion
Provides strong adhesion with epoxy, polyurethane, chlorinated rubber, alkyd, and fluorocarbon coating systems, supporting use within different multi-coat protection systems.
Wide Service Temperature Range
The coating is suitable for steel exposed to organic solvents and chemicals within a temperature range of –20°C to +120°C.
High-Build Protective Coating
The recommended dry film thickness is 100–150 μm, providing a substantial intermediate protective layer within a multi-coat system.
Key Application
Epoxy Micaceous Iron Oxide Coating is designed for protective coating systems on steel, aluminum, and concrete where an effective intermediate barrier layer is required.
Steel Structures
Used as an intermediate protective coating for steel structures in demanding service environments.
Galvanized Steel
Can be used as a primer on galvanized steel where the specified surface preparation and coating system are suitable.
Blast-Cleaned Steel
Applied to blast-cleaned steel as a primer or intermediate protective coating.
Industrial Equipment
Suitable for steel equipment exposed to organic solvents and chemicals within the specified service temperature range.
Aluminum Structures
Can be incorporated into compatible coating systems for aluminum substrates.
Concrete Structures
Compatible with epoxy primer systems on concrete and can be used as part of a suitable multi-layer protective coating system.
Q&A
Is Epoxy Micaceous Iron Oxide Coating a one-component or two-component system?
It is a two-component coating consisting of KGE-8303 Part A and KGE-H081B curing agent.
What is the main role of Epoxy Micaceous Iron Oxide Coating in a coating system?
It is primarily used as an intermediate coating to provide an additional protective barrier between the primer and topcoat. It can also be used as a primer on suitable galvanized or blast-cleaned steel surfaces.
Can it be used directly on galvanized steel?
Yes. The product can be used as a primer on galvanized steel when the substrate is appropriately prepared and the complete coating system is compatible.The product is specified for use with compatible coating systems on aluminum and concrete, in addition to steel.
Can it be overcoated with fluorocarbon coatings?
Yes. It provides strong intercoat adhesion with fluorocarbon coating systems, making it suitable for use as an intermediate layer beneath compatible fluorocarbon topcoats.
