ATL Composites Pty. Ltd. (Southport, Australia) has formulated its new extrudable epoxy tooling paste, TECHNIREZ R2570, to produce a low-density surface that is said to be well suited for large-tool construction. The paste is applied onto a customer-provided backing structure via dedicated extrusion equipment. The material reportedly exhibits minimal shrinkage and has excellent adhesion to expanded foam backing structures made from either polystyrene or polyurethane. Applicable to 40-mm/1.6-inch thickness on complex and vertical surfaces, without sagging, the paste can be machined, after cure, to produce a seam-free, uniform, dimensionally stable tool surface.
