Jesmonite AC300 is a water-based, two-component, acrylic polymer/mineral resin system. The system is suitable for a wide range of casting and laminating applications where the end user wants to reduce the many risks associated with conventional solvent based systems. A range of ancillary products including decorative and functional fillers, control chemicals, pigments and glass reinforcements are also provided making the material extremely versatile. The material is designed for internal use only and is fire-resistant and has achieved a Class '0' Fire rating. The material is an economy alternative to Jesmonite AC100 where external durability is not essential.
