– In this case, the response converts them to diglycerides and monoglycerides. – These hydroxyl-containing oils can then be reacted with isocyanates (TDI or IPDI) and thereby type long-chain hydroxyl-terminated polymers that can be dissolved in solvents. – They are applied by brush or spray, and after solvent evaporation, one obtains a movie that crosslinks by air oxidation of the unsaturated oils with the help of catalysts.
