Heat Resistant Paint for Exhaust Systems, Chimneys & Furnaces | 400°C & 600°C Options

Why Ordinary Paint Fails on Hot Metal Surfaces

Exhaust pipes, chimneys, furnaces, boilers and silencers don't just face rust — they face continuous or intermittent heat that ordinary paint simply isn't built for.

On surfaces that run hot, conventional coatings can lose adhesion, discolour, blister or flake off well before the metal underneath actually fails.

That's where a dedicated heat resistant paint becomes essential — not just for appearance, but to keep the coating intact and the metal protected.

Two Heat Resistant Options, Two Different Jobs

FERONIX offers two single-component heat resistant coatings, each suited to a different kind of high-temperature application:

FERONIX THERMAX — Heat Resistant Black Paint (up to 400°C)

Built on modified silicone resin and heat-stable black pigments, THERMAX is designed for metal surfaces exposed to continuous or intermittent dry heat up to 400°C, while maintaining colour stability and adhesion.

• Furnace and oven housings
• Chimneys and stacks
• Boiler exteriors
• Exhaust systems and hot pipelines
• Heat exchangers and engine components

FERONIX ALUMIX — Heat Resistant Aluminium Paint (up to 600°C)

Formulated with a silicone-modified polymer and ultrafine aluminium pigments, ALUMIX is built for even higher operating temperatures — up to 600°C — while giving a durable metallic finish. It's also a Direct-to-Metal (DTM) coating, so it doesn't need a separate primer.

• Automotive silencers, mufflers and exhaust manifolds
• Duct collectors and heater baffles
• Boilers and furnaces running at higher temperatures
• Pipelines and tanks exposed to sustained high heat

THERMAX vs ALUMIX — Which One Do You Need?

If you need a black, colour-stable finish for surfaces up to 400°C, THERMAX is the practical choice. If your surface runs hotter — up to 600°C — or you want a metallic aluminium finish with self-priming DTM convenience, ALUMIX is built for that range.

Both are single-component and ready to use — no two-pack mixing, no pot life to manage on site.

Where These Get Used

Maintenance teams, fabricators and industrial contractors reach for these coatings on equipment where heat — not just moisture — is the main threat to the paint film: exhaust systems, chimneys, furnaces, boilers, pipelines and automotive exhaust components.
