IOTA 6146 Acrylic-Modified Silicone Resin: Ambient Self-Drying, Heat Resistance Exceeding 500°C

Hits: 379 img

Under high-temperature and harsh outdoor conditions, conventional coatings often struggle to balance heat resistance, gloss, and application convenience. IOTA 6146 Acrylic-Modified Silicone Resin combines the high-temperature resistance of silicone resins with the fast curing and high gloss of acrylic resins, making it an ideal binder for high-temperature and ultra-weather-resistant coatings.

Product Features

  • Excellent high and low temperature resistance: Clear coating film on tinplate withstands 200°C for ≥300 hours; when formulated into a coating, heat resistance can reach over 500°C

  • Fast surface drying, convenient application: Reaches thumb-dry in about half an hour at room temperature – no high-temperature baking required

  • Good gloss and hardness: Cured film exhibits bright appearance, good hardness, and excellent gloss and color retention

  • Easy to use: Solvent is xylene, with good compatibility across various coating systems
