K-FLEX XM-391

K-FLEX XM-391 is a solvent free, hydroxyl functional, aliphatic, saturated polyester diol, for use in high solids solvent based industrial coatings. It is recommended as a reactive modifier for amino or blocked isocyanate crosslinked coatings. K-FLEX XM-391 was designed to be approvable for packaging coatings under FDA 175.300 for direct contact with foods. K-FLEX XM-391 is a semi-solid at toom room temperature. It will melt clear at 65°C and then super-cool clear for a few hours before crystallizing again.
