Product Description

Chemical Composition: Dimeric 2.4-toluene diisocyanate
Molecular weight: 348
Specific gravity: Approximately 1.48 g/ccm
Appearance: Fine, white powder
Package: 50 lb per box
Storage Stability: 24 months under dry and cool conditions

Functionality

Under mild reaction conditions, i.e. at up to ~ 130º C in the absence of basic catalysts, it is primarily bifunctional and has 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) it still reacts primarily bifunctional but with an molecular weight of 174; accordingly the central uretdione group splits under the formation of monomeric TDI.

Please refer to the Material Safety Data Sheet and to the available literature regarding the handling of TDI.

Applications

Thanecure T9 is used as a vulcanization chemical for certain millable polyurethane rubbers, as an adhesion promoter in vulcanizing rubber to textiles, particularly polyester fibers and as a crosslinker in heat activated adhesion, coating or elastomer systems. Thanecure T9 improves the adhesion of rubber to polyester fibers by more than 100% compared to plain RFL dips.
