KeyPRINT® KeyCast® is a highly precise castable resin for investment molding that burns out cleanly with no residual ash. Its low-shrinkage formula controls thermal expansion to produce pore-free, accurate castings, and it is compatible with both rapid-burnout and gradual temperature-ramp workflows.
