This three-component, polyurethane casting system features good dimensional stability, low shrink, and rapid cure.

The addition of the DT 081 (1:1:1 ratio) is a quartz microsphere filler that will give you lower density, lower CTE, increased hardness, and increased temperature resistance. The addition of the DT082 (1:1:3 ratio) will lower CTE, increase density and hardness, and not affect the strength of the casting.

The addition of either filler makes this material ideal for foundry patterns, pattern plates, core boxes, cores, gating, risers, prototypes, jigs and fixtures.
