Solubility / thinnability
Compatibility with the following solvents is generally good but the storage stability of the respective solutions should be tested.Desmophen® C XP 2613 is reducible with esters, ketones, aromatic hydrocarbons and ether esters.Prolonged storage of a solution with low binder content may result in turbidity and sedimentation.Only PU grade solvents (< 0.05 % water, free of other reactive impurities) should be used.
Compatibility
Desmophen® C XP 2613 is compatible with many Desmophen® and Desmodur® products. Given the many products available, compatibility should always be tested beforehand.
