Thanecure® T9 SuperFine (SF)
Thanecure T9SF is dimerized TDI (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.

Under mild reaction conditions (i.e., at up to ~ 130º C in the absence of basic catalysts), TDI Dimer is primarily bifunctional, with a molecular weight of 348. Under more severe conditions (either at temperatures above 140/150º C or with the aid of highly basic catalysts at temperatures above 90º C) TDI dimer remains primarily bifunctional but with a molecular weight of 174, as the central uretdione group splits to form monomeric TDI. NOTE: Please refer to the Material Safety Data Sheet and to the available literature regarding the handling of TDI.
- Vulcanizing agent for isocyanate-curable polyurethane rubbers, particularly when a high hardness is desired. Applications include industrial molded parts, rollers, ceramic tile molds
- Crosslinker for heat-activated adhesion, coating or elastomer systems
- Adhesion promoter for rubber-to-fabric bonding (polyester, aramid, polyamide). Applications include tire cord, conveyor belts, drive belts, hose, coated fabrics
- Adhesion promoter for PVC-to-fabric bonding (polyester, aramid, polyamide). Applications include coated fabrics, conveyor belts
