ELANTAS TU-8040

Main features

1:1 Controlled Mixing
1,700 cP Mixed Viscosity
700% Cured Elongation

Product Description

CONATHANE® TU-8040 Polyurethane Tooling Elastomer is an unfilled, two-component, room-temperature-curing, 100% solids polyurethane system for casting tough, highly extensible elastomeric parts. The light-yellow and light-amber components use a cartridge-friendly 1:1 mix ratio by weight and volume. The system is documented for detailed molds and sound-damping pads and has a typical initial mixed viscosity of 1,700 cP, 30-minute work life, and 60-minute gel time at 25°C. After cure, the material has Shore A 40 hardness, 700 psi tensile strength, and 700% elongation.

Key features

Cartridge-friendly 1:1 ratio: The two components mix 1:1 by weight and volume.
Low mixed viscosity: Typical initial mixed viscosity is 1,700 cP with a 30-minute work life.
Soft high-elongation elastomer: Typical cured properties include Shore A 40 hardness and 700% elongation.

Applications / Suitable for

Detailed mold casting
Sound-damping pads
Tough flexible polyurethane castings
