Technical Data Sheet
K-FLEX XM-386 is a solvent free, water soluble, hydroxyl functional, aliphatic, saturated urethane diol, for use in waterborne industrial coatings. It is recommended as a reactive modifier for amino crosslinked waterborne coatings based on polyester, acrylic, alkyd, and urethane resins. K-FLEX XM-386 is also recommended as a replacement for co-solvent in low VOC formulations, and it is compatible with most waterborne dispersions, emulsions and solutions.
