一般特征

Desmodur RC is a 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.

储存条件

Desmodur RC should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. 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. Recommended storage temperature is 0º-30ºC.
