K-FLEX® UD-320 is an aliphatic, high solids, low molecular weight urethane diol oligomer. It is soluble in polar organic solvents except aliphatic and aromatic hydrocarbons. To gain aromatic solubility it has to be combined with a hydrogen bonding solvent. This product has broad compatibility with acrylic, polyester, and alkyd resins. K-FLEX® UD-320 enhances the hardness of melamine crosslinked systems. When used to modify a 2-component polyurethane, it will enhance hardness and flexibility. K-FLEX® UD-320 responds best to a zirconium chelate catalyst when used in isocyanate crosslinked systems. It also offers benefits like low VOC, chemical resistance, exterior durability, QUV resistance, and hydrolytic stability. This product can be used for machine/equipment coatings, automotive coatings, appliance coatings, wood and paper coatings, and aerospace coatings.
King Industries, Inc. offers a broad range of products used in formulating high performance industrial and automotive, aerospace, and ballistic grade additives for coatings.
