K-FLEX® 171-90 is a highly reactive, aliphatic polyester polyol that is suggested for aminoplast or isocyanate crosslinked coatings, sealants, inks, elastomers, and adhesives. Although it is slower reacting in isocyanate crosslinked systems, it offers long pot life, enhanced adhesion and flexibility. Because of its lower hydroxyl number, K-FLEX® 171-90 requires less crosslinker. K-FLEX® 171-90 can also be used as a modifier of aminoplast crosslinked coatings, inks and adhesives to enhance flexibility and adhesion. It appears as a clear, light straw liquid and offers high resistivity and low temperature cure. This product is soluble in esters, ketones, alcohols, aromatic 100 and aromatic 150, and xylene. It is partially soluble in mineral spirits and is insoluble in water. It can be used in office furniture coatings, 2K urethane coatings, appliance coatings, elastomeric coatings, coil coatings, and epoxy flexibilizer.
