Jesmonite AC100 is a 2-part, water-based composite material used to make decorative moulded objects and glass reinforced laminates. These materials have a range of unique properties, which contribute to strength, durability, non-toxicity, and the ability to comply with many of the necessary test requirements of the construction industry, specifically those in regard to fire performance and impact resistance. It is safe to use and contains no solvents or volatile organic compounds and can be pigmented using the Jesmonite range of water-based pigments. It is also possible to add a range of decorative and functional fillers in order to achieve a wider range of effects and to meet a broader spectrum of specifications. It is weather resistant and suitable for both interior and exterior use and is harder and has a higher impact strength than that of AC300.
Jesmonite AC100 can be used both internally and externally, although external use requires the application of a suitable sealer or external paint system for long-term exposure. It is fire-resistant, having achieved a Class '0' fire rating under UK Building Regulations BS476 (Parts 6&7). Due to its solvent free formulation, AC100 can be cast without damage to rubber moulding compounds, and without limitation to scale. It is also dimensionally stable due to low exothermic reaction, and produces a small amount of expansion on set (1mm/ linear metre).
AC100 is supplied in separate containers of liquid and powder, and mix ratios are variable to allow for both decorative and functional fillers. Normal casting and laminating requires a mix ratio of 2.5 parts AC100 Powders to 1 Part AC100 Liquids, by weight. A ratio of 3:1 is often used when applying directly onto polystyrene.
A full range of ancillary materials designed specifically for optimum compatibility are available. These include Stone & Metal Fillers, Thixotrope, Retarder, Pigments, and Glass Reinforcements
