In general, Desmodur® L 75 has good compatibility with esters such as ethyl acetate, butyl acetate and 1-methoxypropylacetate-2 and aromatic hydrocarbons such as toluene, xylene, Solvesso 100 and Shellsol® A. However, the solutions formed must be tested for their storage stability. The product is not compatible with aliphatics. Alcohols react with Desmodur® L 75 and therefore cannot be used. Prolonged storage of a solution with low binder content may result in turbidity and sedimentation. Only PU grade solvents should be used (< 0.05 % water). The solvent should not contain reactive groups.
Desmodur® N 75 MPA/X is used primarily as the hardener component for lightfast two-component polyurethane coatings with high resistance to chemicals and weathering, very good gloss retention and outstanding mechanical properties. Preferred co-reactants are polyacrylate or polyester polyols. The main applications for systems based on Desmodur® N 75 MPA/X are as air- and force-drying coatings for automotive and industrial finishing, for wood, furniture and plastics and for corrosion protection.
