Tough-Cast 75D Polyurethane Casting Resin, 1-Gal, High Impact & Heat Resistant, Ideal for Prototypes, Reproductions, Sculptures, Automotive Parts, Crafts, and DIY Projects

Tough-Cast 75D is a high-performance, two-component polyurethane casting resin engineered for strength, durability, and precision. With a convenient 1:1 mix ratio by weight or volume, it’s easy to use for both hand-mixing and automated dispensing. This clear amber resin features low viscosity, allowing for smooth pours and minimal bubble entrapment, making it ideal for detailed molds and complex designs. It cures quickly, with a 6–7 minute working time and a 60-minute demold time, streamlining your workflow without compromising quality. Designed to withstand impact, deformation, and harsh conditions, Tough-Cast 75D is virtually indestructible once cured. It’s also low-odor, solvent-free, and offers excellent chemical resistance. The clear amber base makes coloring simple and effective, giving creators flexibility for vibrant or natural finishes. Tough-Cast 75D is perfect for creating tough prototypes, taxidermy replicas, industrial components, automotive parts, sculptures, models, and reproductions. Whether you're a professional fabricator or a dedicated hobbyist, this resin delivers consistent, reliable results every time.
