IOTA-6056D is a high-performance phenyl silicone resin offering excellent high/low temperature resistance, water repellency, moisture resistance, electrical insulation, arc and corona resistance, weatherability, and chemical stability. It dries quickly at ambient temperature, and after full curing, the film exhibits high hardness (≥2H), high gloss, excellent fullness, no yellowing at high temperatures, and low smoke generation.
IOTA-6056D is widely used as a base resin for high-temperature resistant coatings (≥500℃) and specialty coatings, as well as Class H insulation coatings.
