HT Silicone Coating

The DESIGN ENGINEERING HT Silicone Coating is a professional-grade high-temperature silicone spray engineered for exhaust system protection and thermal management in automotive applications. Built for mechanics and enthusiasts who demand reliable heat shielding, this 12 oz aerosol delivers a flexible, durable black silicone finish that adheres to exhaust wrap, headers, and heat-sensitive engine bay components. Whether you're wrapping a performance exhaust or protecting factory components from radiant heat, this coating provides the thermal barrier needed to extend component life and reduce underhood temperatures.

This high-temperature silicone formulation cures to a tough, flexible coating that withstands continuous exposure to extreme heat while preventing thermal degradation of surrounding materials and wiring. The aerosol application method ensures uniform coverage and easy integration into existing exhaust wrap installation workflows—spray directly onto wrap before or after installation for enhanced thermal retention and cohesion. The silicone binder maintains elasticity across wide temperature swings, resisting cracking and peeling that plague rigid coatings, while the black pigmentation helps conceal discoloration and provides additional UV protection to wrapped surfaces.

Technicians and fabricators rely on this coating for professional exhaust wrap jobs, turbo installations, and custom engine builds where temperature management is non-negotiable. The 12 oz can covers approximately 15–20 linear feet of standard wrap width, making it economical for single-system applications or shop stock. Compatible with all standard fiberglass and ceramic exhaust wraps, and applicable to headers, mufflers, downpipes, and intercooler piping, this product is essential for any serious modification or restoration project requiring thermal protection and lasting durability.
