It meets USDA standards and is suited for automotive, industrial or maintenance tasks where flexible surfaces need long-term protection.

Dielectric Strength and Temperature Range

The film provides a dielectric strength of 11.8 kV/mm and remains stable from -30 degrees to 200 degrees F. This single electrical and thermal specification determines whether the coating meets the insulation and environmental demands of your specific application.

Brush-On Application With Four-Hour Dry Time

The product is supplied in a 14.5 fl oz container for brush, roller or sprayer use and dries in 4 hours. Apply only within the stated temperature window; surfaces must be clean and dry, and the 0.74 g/L VOC content requires adequate ventilation during use.

Questions about this item

What does the 11.8 kV/mm dielectric strength mean when the coating is applied to a part?

It indicates the cured film can withstand 11.8 kV per millimetre of thickness before electrical breakdown, so it provides insulation on rubber or plastic components.

How does the 0.74 g/L VOC content affect use in a shop?

The very low VOC level means minimal solvent odour and easier compliance with air-quality regulations during application.

Will the 14.5 fl oz aerosol can reach tight spots on a mounted rubber seal?

The spray nozzle delivers a directed mist that can coat intricate profiles, and the can works at any angle for hard-to-reach areas.
