9081-90-7 Usage
General Description
Desmodur L 75 is a polyisocyanate based on toluene diisocyanate (TDI), which is typically used as a curing agent or hardener component in polyurethane coating systems. It is supplied as a 75% solution in an aromatic solvent blend and has a relatively low viscosity, making it easy to handle and blend with other components. Desmodur L 75 is noted for its high reactivity, ease of use, and exceptional cross-linking capabilities, providing excellent durability, chemical resistance, and performance characteristics to the finished coating. However, due to its isocyanate content, it requires careful handling and appropriate protective measures to prevent exposure and potential health effects.
Check Digit Verification of cas no
The CAS Registry Mumber 9081-90-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,8 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 9081-90:
(6*9)+(5*0)+(4*8)+(3*1)+(2*9)+(1*0)=107
107 % 10 = 7
So 9081-90-7 is a valid CAS Registry Number.
