Crystalcal R Casting & Moulding Powder is a 100% Alpha Plaster. This means it is the hardest and most durable plaster that we stock. It is even harder than Herculite 2 and is very close to dental plaster in strength. It will cope with lost wax casting without any problem. It has a set time of between 10-25 mins depending on your water temperature, ambient temperature and age of the material.
If your current suppliers Crystacal is setting faster than 10 minutes then its really really old! The older the plaster the quicker it will try to set. This is a premium plaster and will reproduce very fine detail. It is similar setting material in time compared to Herculite 2 or Plaster of Paris. We NEVER supply plaster thats older than 4 months.
Whether its a figurine or a fridge magnet, chess piece or just about anything else, if its strength and durability you want, or indeed you intend to use it for lost wax casting in foundries this is the plaster product you need!
We also supply Herculite 2, Plaster of Paris Fine Casting, Fibrocem, Herculite Stone & Polymer Plasters. Check out our Casting Plaster Section of our shop today, if its plaster and you can cast it we probably have it!
The shelf life of this product to perform to exact specification is around 4 months, though keep it dry and in a plastic bag and it will last. As stated it will get faster on set time until virtually unusable. The datasheet relating to this product should answer most questions relating to the product. See the Crystacal R data sheet.
Water to Plaster correct ratio according to Bristish Gypsum is 100:35.
We have a range of flexible casting bowls for mixing small quantities. They are THE industry standard bowl and readily flex to eject solid set plaster. No more hammering it or picking it out. Search now for Flexible Plasterers Knock Out Bowl.
