Fine textures Fine textures can be imparted by compression moulding using the corresponding tools. Rough textures Rough textures are produced by casting. Painting/varnishing The appropriate pre-treatment and special paint systems allow the surface of the mouldings to be subsequently coated. Dyeing Vulkollan Muted colours can be taken into account in the casting process. Darkening is possible but does not alter the performance profile of Vulkollan.
