Jesmonite AC100 (Liquids, Powders and Kits)

Jesmonite AC100

Jesmonite AC100 is a water-based, two-component (acrylic polymer and mineral resin) system from Jesmonite®.

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 suitable for internal and external use, however if used externally a sealer or suitable paint system is recommended to protect surface appearance.
