Fast-curing Polyurethane Casting Resin for Prototypes and Sculptures

Fast-curing Polyurethane Casting Resin for Prototypes and Sculptures. TECHNO CAST 3272D is a professional-grade two-component polyurethane casting resin designed for detailed molding and lightweight, high-strength plastic parts. Ideal for rapid prototyping, sculpture reproduction, special effects, taxidermy, and point-of-purchase displays, this casting system mixes easily in a 1:1 ratio by volume and cures at room temperature.

TECHNO CAST 3272D offers a fast pot life of 3 minutes and demolds in just 20 minutes, making it perfect for high-turnaround projects. Once cured, it can be sanded, drilled, painted, or machined. The cured resin forms a durable, creamy white finish with impressive compressive and flexural strength. Compatible with both rigid and flexible molds—including silicone—this versatile polyurethane resin ensures excellent surface detail reproduction with minimal shrinkage and high dimensional stability.

Whether you’re a professional model maker, FX artist, or hobbyist, TECHNO CAST 3272D delivers consistent performance for all your casting needs.
