Intrepid Coatings TT-P-28G (1-US-GALLON-CAN)

TT-P-28G High Heat Coating

Overview

TT-P-28G High Heat Coating is a ready-mixed silicone resin coating formulated to withstand continuous exposure to high temperatures of up to 1200°F (649°C). Designed for aerospace and industrial applications, this durable air-drying coating provides long-lasting protection for bare steel components operating in extreme heat environments. It can be applied by brush, roller or spray without the need for a primer, provided direct metal-to-coating contact is maintained.

Why This Product is Chosen for AOG / MRO

• Provides durable protection for components operating at extreme temperatures
• Air-drying formulation simplifies maintenance without specialised curing equipment
• Multiple application methods support both workshop and field repairs
• No primer required, reducing preparation time and material costs
• Ideal for restoring high-temperature aircraft and ground support equipment

Practical Suggestions for Your Team (AOG Mindset)

• Ensure complete removal of rust, scale and contaminants before coating
• Apply two thin coats rather than one heavy coat for optimum durability
• Maintain the recommended dry film thickness to achieve maximum heat resistance
• Use appropriate thinning solvent depending on the chosen application method
• Allow the coating to fully cure before exposing components to high operating temperatures
