ELANTAS TU-6090
Harmonization Code : 3910.00.00.90 | Silicones in Primary Forms; Others

Main features
- Equal-Volume Two-Part Mixing
- Fifteen-to-Twenty-Minute Work Life
- Shore A 90 Tooling Elastomer
Product Description
CONATHANE TU-6090 Two-Component Polyurethane Casting System is an unfilled, 100% solids two-component polyurethane tooling elastomer for casting flexible parts. Part A and Part B are mixed at 100/50 by weight or volume, producing a typical mixed viscosity of 3,100 cP at 25 deg C and a 15 to 20 minute work life. The system cures for 7 to 10 days at 25 deg C or 16 hours at 60 deg C. The cured elastomer reaches Shore A 90 hardness, 2,850 psi tensile strength, and 335% elongation.
Key features
- Equal Weight-or-Volume Ratio: The 100/50 mix ratio applies by weight and by volume.
- Fifteen-to-Twenty-Minute Work Life: The mixed system has a typical 15 to 20 minute processing window at 25 deg C.
- Shore A 90 Elastomer: The cured tooling elastomer combines Shore A 90 hardness with 335% elongation.
Applications / Suitable for
- Industrial wheels and rolls
- Metal-forming pads and flexible molds
- Washers, gaskets, bushings, and vibration-dampening pads
