Thanecure® T9 (TDI Dimer)

Thanecure® T9 polyester-to-rubber adhesion promoter has been developed for high-performance products to keep them operating through temperature extremes, fatigue, moisture, and stress. Thanecure® T9 allows superior rubber products to perform longer without fear of adhesion failure.

Read the Thanecure® T9 Bulletin on how the adhesion promoter works with bonding rubber to textiles.

Thanecure® T9SF (SuperFine) is the dimer of 2,4-toluene diisocyanate. It is a polyfunctional isocyanate used primarily as a vulcanizing agent for polyurethane rubbers, as a crosslinker for heat-activated adhesive systems, and as an adhesion promoter for rubber-to-fabric bonding.

Thanecure® T9 Applications

  • Vulcanizing agent for isocyanate-curable polyurethane rubbers, particularly when a high hardness is desired. Applications include industrial molded parts, rollers, and ceramic tile molds.
  • Adhesion promoter for rubber-to-fabric bonding (polyester, aramid, polyamide). Applications include tire cords, conveyor belts, drive belts, hoses, and coated fabrics.
  • Crosslinker for heat-activated adhesion, coating, or elastomer systems.
  • Adhesion promoter for PVC-to-fabric bonding (polyester, aramid, polyamide). Applications include coated fabrics and conveyor belts.
