Product Description

IOTA 9970 is a specialty organopolysilazane-based automotive coating liquid. Unlike popular coatings primarily composed of siloxanes, IOTA 9970 forms a silica (SiO₂) film after crystallization. The cured coating has high hardness, good transparency, excellent oxidation and UV resistance, strong adhesion, and water-repellent properties. It also enhances the gloss of automotive paint, especially for black vehicles. The product provides outstanding durability.
