Q: I am having difficulty getting a good bond with my first stage pour and second stage pour silicone. How can I improve the adhesion between silicone and silicone?
A: It is best to pour your second stage pour silicone within 6-8 hours of your first stage pour to assure a good chemical bond.
Q: Our wax injection molds were made out of RenShape 2000, which has been discontinued. Do you have an alternative board that could easily handle the 150°F temperature of the wax and wax release?
A: We would suggest our RenShape 5179 red foundry board which can be machined to a Class A finish.
