K-FLEX® A307 is a low viscosity, 100% solids linear, saturated, aliphatic polyester diol with primary hydroxyl groups. This product was created as a flexibility modifier for acrylic/isocyanate and acrylic/melamine systems. The low hydroxyl number minimizes the crosslinker demand.

It appears as a clear viscous liquid and is soluble in esters, alcohols, xylene, ketones, aromatic 100, and aromatic 150. It is partially soluble in mineral spirits and is insoluble in water. It can be applied in automotive refinish, automotive OEM, industrial maintenance, aerospace, and plastic coatings.
