Product Line: 2080B - LAB - CASTING - RING LINERS
This material has the necessary cushioning and the correct water absorption, which enables the investment to control setting expansion. During burnout it chars to a black ash which crumbles easily when the mold is pushed out of the ring. Liners should be 3mm (1/8″) short of each end of the casting ring.
