K-FLEX

K-FLEX® XM-337 is an aliphatic saturated polyester diol modifier resin designed to provide increased toughness and chemical resistance for solvent-based and high solids systems. It is recommended for use in 1 and 2 component polyurethanes, and blocked isocyanate systems. Benefits include low color, UV durability, high hardness, high impact resistance, abrasion resistance and overall increased toughness.

K-FLEX® 171-90 is a chain extended version of K-FLEX® 188 with low crosslinker demand. Although it is slower reacting in isocyanate crosslinked systems than K-FLEX® 188, it offers improved adhesion and flexibility.

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.

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® 148 is a lower viscosity version of K-FLEX® 188 designed for formulating higher solids content with good hardness and increased flexibility.

K-FLEX® A307 is a low viscosity, 100% solids linear, saturated, aliphatic polyester diol. This product is designed as a flexibility modifier for acrylic/isocyanate and acrylic/melamine systems.

K-FLEX® A308 is a low-viscosity polyester diol designed as a flexibility modifier for acrylic/isocyanate and acrylic/melamine systems. K-FLEX® A308 provides good hardness and adhesion while allowing lower VOC levels.

K-FLEX® XM-332 is an ultra low-viscosity polyester polyol modifier resin designed to provide improved flexibility in solvent-based, high solids and solventless systems. Compared to other K-FLEX® polyester diols, XM-332 produces the softest films. K-FLEX® XM-332 is recommended for use in air dry/force dry 2-component polyurethanes and blocked isocyanate systems.

K-FLEX® UD-320-100 a 100% solids version of K-FLEX® UD-320 recommended for prepolymer synthesis and 100% solids WB/SB melamine crosslinked systems or 2K PU. Used for preparation of polyester polyurethanes or alkyd polyurethanes. It provides hardness and exterior durability.

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® UD-350W is an aqueous solution of an aliphatic, low molecular weight urethane diol oligomer. It is recommended as a modifier for amino crosslinked water soluble and emulsified acrylic, alkyd, urethane and polyester resins. K-FLEX® UD-350W can be used as a reactive cosolvent replacement to increase solids, crosslink density, improve film/resistance properties and flow/leveling.

K-FLEX® XM-B301 is a low-viscosity, acetoacetate functional reactive diluent with excellent compatibility with a wide range of resins. It is primarily recommended for use in epoxy/polyamide primers, but can also be used in systems crosslinked with amino resins or polyisocyanates.
