Main features

15 to 25-Minute Working Window
22.1 MPa Cured Tensile Strength
Flexible Cured Material

Product Description

CONATHANE® TU-89MF Polyurethane is a two-component amber polyurethane casting material for tough, flexible elastomeric parts. The system is documented for acoustic barriers, belt repair, bushings, diaphragms, gaskets, molds, pulleys, washers, and wheels. It uses a 100:53 resin-to-hardener ratio by weight and has a typical pot life of 15 to 25 minutes at 25°C. Typical cured properties include Shore A 89 hardness, 22.1 MPa tensile strength, 600% elongation, 74.4 kN/m tear strength, and resistance to abrasion, chemicals, and solvents.
