Hexamethylenediamine carbamate

Crosslinking Perfluorophenoxy-Containing Elastomers. Vulcanization of the perfluoroelastomer containing a phenoxy group may be carried out several ways. One method uses diamines such as p-phenyl-enediamine, tetraethylenepentamine, or hexamethylenediamine carbamate (Du Pont DIAK No. 1) (3). A typical recipe is shown in Figure 8.

Free diamines, used for crosslinking, are too reactive and can cause premature gelation. It is therefore common practice to add these diamine compounds in the form of carbamates, like ethylenediamine carbamate or hexamethylenediamine carbamate. The above fluoroelastomers exhibit good resistance to chemicals and maintain useful properties from -50 °C to +300 °C.

Trifluoronitrosomethane-tetrafluoroethylene copolymer may be vulcanized with a combination of triethylenetetramine and hexamethylenediamine carbamate typically, vulcanization is effected by heating at 250 C for 1 hour in the press and then 210°C in an oven for 18 hours. The mechanism of the process is unknown.

The selection of a preferred diamine cure system depends on the priority of properties and processing constraints. Hexamethylenediamine carbamate, HMDC, is the best general-purpose curing agent and the most widely used. Table 6.17 shows the property trends expected as a function of HMDC level and the accelerator preferred for the optimization of specific properties.
