Acrylic-Modified Methyl Silicone Resin
Acrylic-Modified Methyl Silicone Resin is a hybrid resin combining the heat and UV stability of silicone with the adhesion and hardness of acrylics. It’s used in heat-resistant coatings, architectural finishes, protective paints, and insulating varnishes for durable, weather-resistant performance.
Product Overview
Acrylic-Modified Methyl Silicone Resin is a high-performance hybrid polymer designed by chemically bonding acrylic functional groups onto a methyl MQ silicone resin backbone. This dual-structure resin offers the thermal and UV stability of silicone resins and the strong adhesion, hardness, and film-forming properties of acrylic polymers.
It is widely used in heat-resistant coatings, weatherable architectural finishes, protective paints, and electrical insulating varnishes, offering outstanding durability, gloss retention, and substrate compatibility in harsh environments.
