Solubility / thinnability
Desmophen® 1300 X can be thinned with esters, ketones, ether esters and aromatics hydrocarbons. However, the solutions formed must be tested for their storage stability.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, free from other reactive impurities).
Compatibility
Generally speaking, Desmophen® 1300 X is compatible with many polyesters and Desmodur® grades.Given the many products on the market, compatibility testing is always advisable.
