Name: Youmai TDI-65 Curing Agent
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Youmai TDI-65 Curing Agent

High reactivity with hydroxyl-terminated polyethers and polyesters for rapid gelation and short demold times.
Excellent compatibility with aromatic and aliphatic polyol systems, ensuring homogeneous mixing and stable prepolymers.
Low volatility and controlled exotherm profile, enhancing process safety and reducing bubble formation in casting applications.
Consistent batch-to-batch performance due to stringent purification and residual TDI monomer control (≤0.1 wt%).
Enables production of elastomers with high tensile strength, abrasion resistance, and thermal stability up to 100 °C.

Typical Applications Of Youmai TDI-65 Curing Agent

Polyurethane elastomer castings for mining screens, industrial rollers, and hydraulic seals.
Reaction injection molding (RIM) components in automotive suspension bushings and structural gaskets.
High-performance polyurethane adhesives and sealants requiring fast fixture and elevated temperature resistance.
Coating systems for concrete and metal substrates demanding chemical resistance and mechanical durability.
Microcellular polyurethane foams used in precision gasketing and vibration-damping pads.
