General Characterization

Desmodur L 75 is an aromatic polyisocyanate based on toluene diisocyanate (TDI).
It can be used in combination with various Desmophen®, Baycoll®, Desmocoll® grades or other hydroxyl-bearing substances to formulate two-component polyurethane coatings and adhesives.

Storage Conditions

Desmodur L 75 should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. Storage at higher temperatures will result in increase of color and viscosity. Storage at significant lower temperatures will result in solidification. This solidification is reversible by briefly heating the product without adversely affecting the quality of the product. Recommended storage temperature is 0º-30ºC.
