MORE INFO
Particularly hard, fast-hardening, cream-white alpha hemihydrate plaster for the production of casts and moulds where very high strength is required. Due to its low expansion during hardening, CALCAST 300 offers high casting accuracy at a higher hardness. CALCAST 300 is suitable for all applications where high hardness and strength are required. Not weather-resistant (sealing required).
Due to its good absorption capacity, CALCAST 300 is also suitable for the production of casting moulds for ceramic materials. CALCAST 300 is also very suitable for frames and ornaments.
