LE Additive Polymer

LE Additive is a high-quality slurry additive for precision investment casting use.

Designed to improve green strength and dimensional stability, LE Additive enhances ceramic shell performance in the primary coats of the shell building process. It strengthens the shell before firing, helping prevent cracking, sagging, or deformation, and is particularly useful when working with delicate or thin-walled patterns created through additive manufacturing (AM) methods like SLA or resin 3D printing.

LE Additive supports tight dimensional control, even in complex molds, and helps reduce casting defects, inclusions, distortion, and shell failure. It is fully compatible with common binder systems and refractory materials, integrating easily into the primary slurry. With clean burnout characteristics and reliable shell behavior under thermal stress, foundries rely on LE Additive to increase casting yield, reduce rework, and maintain shell integrity—even under demanding production timelines.

Ships in 1 gal containers, 5 gal pails, and 55 gal drums.
