K-FLEX XM-383

K-FLEX XM-383 is a solvent free, low viscosity, water soluble, hydroxyl functional, aliphatic, saturated polyesterurethane 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-383 is also recommended as a replacement for co-solvent in low VOC formulations, and is compatible with most waterborne dispersions, emulsions and solutions. It provides a good balance of hardness with flexibility.

ADVANTAGES:
Lower VOC
Good balance of hardness and flexibility
Improved adhesion, flow and leveling
Exterior durability
Reduced popping and blistering during cure
No co-solvent required
Water soluble in absence of amine, colsolvent or surfactant
