IOTA 6146A is an acrylic modified silicone resin offering excellent high/low temperature resistance, water repellency, moisture resistance, weatherability, and chemical stability. It dries at ambient temperature, and after full curing, the film exhibits high hardness (≥2H), high gloss, excellent fullness, and outstanding gloss and color retention.
When combined with polyurethane curing agents (such as N3390), it achieves full curing to produce high-performance polysiloxane topcoats. IOTA 6146A is widely used in high-temperature resistant coatings (200–400°C) and weather-resistant coatings.
