- For larger projects
- Specially for castings
- No solvents, no smell
Acrystal Optima is a low-cost casting material. Ideal for larger projects where price is an issue. This material is also suitable for making gel coats so that the surface of the casting can be made with the same material.
Acrystal Optima is water-based, fast-curing and safe to use. It gives a hard surface and is safe for foams such as polystyrene.
Casting Acrystal Optima can be done ideally in silicone moulds.
