The cure rate of Crystal Cast is affected by temperature, the product must be cast at temperatures greater than 20°C. Exact cure time will depend on the size and geometry of the casting and should be determined by customer testing. Thinner castings will take longer to cure than thicker castings, but generally, the product can be demoulded after 24 hours at 25°C.Incomplete cure can result in slight distortions or deformations of the components if forces are applied.
