Crystacal R

Crystacal R is a premium formulated hemihydrate plaster (CaSO4.½H2O) produced from naturally occurring high-purity gypsum mineral. It is used to make hard casts with fine reproduction of detail, making it the highest-specification casting plaster in the CFS Fibreglass range and the material of choice where surface finish and dimensional accuracy are critical.

Crystacal R is used in the manufacture of glass reinforced gypsum structures, decorative plasterwork, giftware, and dental models - anywhere that demands a consistent, hard, and finely detailed cast. Off-white in colour, it mixes readily with water and is suitable for both small-scale craft work and high-volume production applications.

Available in 5kg and 25kg quantities. For less demanding applications where a shorter setting time is the priority, see Herculite No. 2.
