Repro Fast-Cast Polyurethanes are world-renowned as the leading class of quick-curing casting resin systems available today. These products are designed for ease of mixing, quick demolding, and unsurpassed accuracy. Repro is manufactured by Freeman and has become the standard against which all other fast-setting castable urethanes are measured.
These systems are ideal for many applications including foundry patterns and tooling, core boxes, protoype vacuum forming tools, holding and assembly fixtures, figurine and decorative castings, duplicator models and tracing aids, back-filling material for other tooling resins, prototype wax injection molds, and prototype parts.
