Compatibility
Desmodur HL BA is compatible with many Desmophen polyesters and has only limited compatibility with hydroxyacrylates. In general, Desmodur HL BA is very compatible with standard Desmodur products.

Solubility/Dilution
Desmodur® HL BA generally has good compatibility with the following solvents. However, the storage stability of the prepared solutions must be tested. Desmodur HL BA can be diluted with ethyl acetate, butyl acetate and 1-methoxypropyl acetate-2. Aromatic solvents are not true solvents and have only limited compatibility as diluents. Solutions with low base material content will appear cloudy and precipitate after prolonged storage. Polyurethane grade solvents should be used (low water content
at 0.05%). These solvents should not contain reactive groups.
