Solubility / thinnability
Generally speaking, Desmodur® HL BA has good compatibility with the solvents listed as follows. However, the solutions formed must be tested for their storage stability. Desmodur® HL BA can be thinned with ethyl acetate,butyl acetate and 1-methoxypropylacetate-2. Aromatics are not true solvents and have only limited compatibility as diluents. 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.
Compatibility
Desmodur® HL BA is compatible with many Desmophen® polyester grades. It has limited compatibility with acrylates containing hydroxyl groups. Generally speaking, Desmodur® HL BA is compatible with standard Desmodur® grades.
Properties / Applications
The rapid initial drying and early sandability are of particular advantage when formulating wood coatings. With just a few coats, high-bodied clear or pigmented finishes can be easily achieved.
