VHT Flameproof Coating, Flat Black
The VHT Flameproof Coating is designed for surfaces exposed to extreme heat, offering protection for exhaust systems, headers, and related components. It withstands temperatures from 1300°F to 2000°F (704°C to 1093°C). The coating is formulated for automotive and aerospace use, providing a durable finish that reduces heat-related damage and visible wear on metal surfaces. Application can be performed on or off the vehicle, with curing requirements to achieve full durability.
Key considerations
- Very high-heat resistance suitable for headers and exhaust components.
- Flat black finish blends with most exhaust systems.
- Requires curing to reach full performance; plan time for curing.
VHT SP101 Flameproof Coating Very High Heat Spray Paint – White
This flameproof coating provides a high-heat, ceramic-based finish in a white flat style. It’s widely used on automotive exhaust components and other high-temperature surfaces where a clean, reflective light color is desired. The coating works best when used with primers and a clear coat sequence for enhanced durability. It’s formulated to resist heat, chemicals, and environmental exposure common to under-hood applications.
Key considerations
- High-temperature performance with a matte white finish.
- Recommended as part of a multi-coat process for best longevity.
- Good visibility for heat-damaged areas or inspection points.
KBS Coatings 65328 Pure White Xtreme Temperature Coating
The KBS Pure White Xtreme Temperature Coating is engineered to withstand continuous temperatures up to 1500°F. It provides robust heat and weathering resistance without peeling, flaking, or chalking. This coating is well-suited for headers, exhaust systems, and other high-heat automotive parts where a durable, white finish is desired. It offers a reliable protective layer against corrosion and heat-driven deterioration.
Key considerations
- Excellent heat resistance and weathering durability.
- Pure white finish with strong adhesion properties.
- Long-lasting protection against peeling in hot environments.
Seymour 16-1201 Hot Spot High Temperature Paints, Aluminium
Seymour’s aluminum high-temperature paint offers a specialty formulation designed to withstand up to 1200°F continuously. It creates a porcelain-like bond at high temperatures and resists blistering, peeling, discoloration, and loss of adhesion. This makes it a strong choice for headers and other heat-sensitive automotive parts that require a light-colored or metallic finish to aid inspection and heat management.
Key considerations
- Aluminium finish that complements many engine bays.
- Strong resistance to blistering and temperature cycling.
- Well-suited for high-temperature exhaust areas requiring a lighter look.
POR-15 High Temperature Paint
POR-15 High Temperature Paint provides a robust coating for metal surfaces exposed to extreme heat and weather conditions. It resists cracking, chipping, and peeling while offering weather and moisture resistance. Suitable for headers and other engine components, it requires a clean, prepared surface and proper curing to ensure the full protective film forms, helping to safeguard metal from corrosion and heat-induced damage.
Key considerations
- Strong resistance to weather, moisture, and high heat.
- Requires surface preparation and correct curing to achieve full performance.
- Gray finish that can blend with many under-hood components.
Buying Guide: Key Purchase Considerations And Comparisons
When selecting a high-heat paint for exhaust headers, buyers should weigh finish aesthetics, heat tolerance, durability, and ease of use. Consider the following factors to compare options effectively:
- Heat tolerance: Most header paints are formulated to endure 1200°F to 2000°F. For headers, aim for at least 1200°F continuous exposure in the coating you choose.
- Finish options: Common finishes include flat black, white, and satin or aluminum. Choose a color that fits your engine bay styling and inspection needs.
- Durability: Look for resistance to blistering, peeling, chalking, and chemical exposure from fuels and degreasers.
- Application and curing: Some products require primer steps or overnight curing with specific temperatures. Plan for proper curing windows to maximize longevity.
- Surface preparation: Clean, dry, and rust-free surfaces improve coating adhesion. Some products need sanding or pre-cleaning before application.
- Coverage and batch availability: Ensure you have enough coating for the exhaust system area you’re treating and consider potential re-coats in the future.
- Environmental and safety factors: Use in a well-ventilated area, with protective gear, since high-heat paints can produce fumes during curing.
