Solubility / Dilution
Generally, it has good miscibility with the following solvents, but the storage stability of the prepared solution must be tested.
Desmophen® C1200 can be diluted with ester, ketone, aromatic hydrocarbon and ether ester solvents. Solutions with low binder content can cause cloudiness and precipitation after prolonged storage.
Urethane grade solvents should be used (water content < 0.05%, no other reactive impurities).

compatibility
Desmophen® C1200 can be mixed with many Desmophen® and Desmodur® products. Considering the wide variety of miscible products, product compatibility should be tested prior to use.

Application .
Coatings and sealers prepared with Desmophen ® C1200 and aliphatic isocyanates have good weather and hydrolysis resistance. Other uses include decorative coatings, sealants and sealants.

store
Desmophen C1200 is hygroscopic and should be stored tightly closed in its original container. This product has a shelf life of at least 6 months when stored in its original container under proper conditions.
Storage at low temperatures can form crystalline precipitates. The crystals can be melted by slow heating at a temperature of not more than 60°C.
