Features Of Mitsui D-260T TDI Trimer Curing Agent

  1. Low-viscosity liquid trimer offering excellent flow and leveling in coating and adhesive formulations.

  2. High functionality with controlled NCO content for balanced reactivity and extended pot life.

  3. Enhanced weather resistance and UV stability compared to conventional TDI-based curing agents.

  4. Compatible with a wide range of hydroxyl-functional resins including polyesters, acrylics, and polyethers.

  5. Meets stringent VOC regulations due to absence of monomeric TDI and low volatility profile.

Typical Applications Of Mitsui D-260T TDI Trimer Curing Agent

  1. Automotive OEM clearcoats and topcoats requiring high gloss and durability.

  2. Industrial maintenance coatings for metal and concrete substrates.

  3. High-performance wood finishes in furniture and flooring applications.

  4. Two-component polyurethane adhesives for laminated packaging and composite bonding.

  5. Electrical insulation varnishes and coil coatings demanding thermal and chemical resistance.
