General 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-coloured adhesives used to bond rubber materials.

Storage Conditions

- Storage in original sealed Covestro container.

- Recommended storage temperature: 0 - 30 °C.

- Protect from moisture, heat and foreign material.

General information: The product is highly sensitive to moisture and react with water to form carbon dioxide and insoluble ureas. The containers must therefore be kept tightly sealed. The ingress of water in any form (damp containers, anhydrous solvents, moist air) must be prevented as otherwise the formation of carbon dioxide may cause a dangerous increase in pressure in the containers. Exposure to air and/or light accelerates yellowing but this has no effect on the processing properties in general.
