Characterization: Solution of a polyisocyanurate of toluene diisocyanate (TDI) in ethyl acetate. Desmodur® RC is suitable for crosslinking adhesives based on Desmocoll®, natural or synthetic rubber, especially pale-colored adhesives used to bond rubber materials. Properties / Applications: After addition of Desmodur® RC, the ready-to-use two-component adhesive must be used within its pot life. This is not only governed by the polymer content of the adhesive but also by its other constituents (resins, antioxidants, plasticisers, solvents, etc.). At the end of the pot life, usually several hours or one working day, the adhesive becomes in-creasingly difficult to work and its viscosity increases rapidly. Finally, irreversible gelling occurs.
