Technology Overview

Union InfernoGuard high-temperature coatings are specifically formulated to protect substrates exposed to extreme thermal conditions. Using advanced silicone resin technology, these coatings maintain their protective properties and appearance at temperatures that would degrade conventional organic coatings, making them essential for automotive, industrial, and consumer applications.

Key Performance Features

Exceptional Heat Resistance

Union InfernoGuard formulations withstand continuous exposure to temperatures from 200°C to 550°C (392°F to 1022°F), protecting metal substrates from oxidation, corrosion, and thermal degradation. This performance ensures long-term protection for components operating in high-temperature environments.

Thermal Shock Resistance

The flexible silicone matrix in Union InfernoGuard accommodates rapid temperature changes without cracking, delamination, or loss of adhesion. This thermal shock resistance is critical for applications experiencing frequent heating and cooling cycles, such as exhaust systems and industrial equipment.

Color Stability at Elevated Temperatures

Unlike conventional coatings that discolor or degrade under heat exposure, Union InfernoGuard maintains color consistency and surface appearance even after prolonged high-temperature service. This stability ensures that components maintain their aesthetic appeal throughout their service life.

Optimal Performance at Low Film Thickness

Union InfernoGuard achieves maximum heat protection at film thicknesses of 40-50 microns, minimizing material usage while maintaining excellent protective properties. This thin-film capability preserves substrate dimensions and allows for application on components with tight tolerances.
