Products in Maintenance, Repair & Overhaul: Polyols

K-FLEX® UD-320 is a high solids, aliphatic, low molecular weight urethane diol oligomer. It is soluble in polar organic solvents and has broad compatibility with acrylic, polyester, and alkyd resins. K-FLEX® UD-320 will increase the hardness of a melamine crosslinked system. When used to modify a 2-component polyurethane, it will increase hardness and flexibility. K-FLEX® UD-320 responds best to a zirconium chelate catalyst when used in isocyanate crosslinked systems.

K-FLEX® XM-359 is designed to provide long pot life in 2K polyurethanes and to prevent yellowing resulting from interaction with benzotriazole (BZT) UV absorbers in clearcoat systems. K-FLEX® XM-359 is a saturated, aliphatic resin modifier.

K-FLEX® 188 is a highly reactive, aliphatic polyester diol which is recommended for aminoplast or isocyanate crosslinked coatings, inks, sealants, elastomers, and adhesives. K-FLEX® 188 is the most versatile polyester diol in the K-FLEX® line.
