Hydracast Art Lux
Hydracast Art Lux is a ready-to-use fine grained refractory investment for artistic applications. This product was developed to produce large (20cm - 2m) ornamental parts from copper alloys. The product can be used within a wide range of mixing ratios, which can be adapted based on mould size. This product is widely used in art foundries.
