Jesmonite AC100 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 suitable for internal and external use, however if used externally a sealer or suitable paint system is recommended to protect surface appearance.
Jesmonite AC100 liquid is used with the Jesmonite Base, so you'll need to order this separately. The standard mix ratio is 2.5:1 Base to Liquid.
The finished colour is basically white, but with a peachy/pink tone. If you want a pure white cast, you need to add the Jesmonite White Pigment. Pigment should be added at a maximum of 2%.
