Product Description

Solubility / thinnability

Generally speaking, Desmodur® IL 1451 BA is well suited to thinningwith esters such as ethyl acetate, butyl acetate, 1-methoxyproplyacetate-2and aromatic hydrocarbons such as toluene, xylene, Solvesso® 100 andShellsol® A. The solutions formed must be tested for their storage stability. Inparticular, prolonged storage of a solution with low binder content may result inturbidity and sedimentation. The product cannot be reduced with mineral spirit.Alcohols react with Desmodur® IL 1451 BA and therefore may not be used.Only PU grade solvents (< 0.05 % water, free of other reactive impurities) maybe used.

Application

The two-component polyurethane systems formulated withDesmodur® IL 1451 BA are characterized by their very rapid initial drying andearly sandability, making them ideal for the industrial coating of wood andfurniture. An NCO/OH ratio of approx. 0.5 - 0.7 is recommended as a functionof the reactivity and hardness of the polyol. With an NCO/OH ratio of 1:1, theDesmodur® IL 1451 BA must be combined with Desmodur® L/ultra L. In thiscase, the optimal ratio of the Desmodur L/ultra L / IL 1451 is a function of polyolhardness and the required drying time. The low viscosity and high reactivityof the Desmodur® IL 1451 BA enables the formulation of clear and coloredcoatings with high solids contents. These can be applied quickly and only afew coats are required.
