Solvent-borne alkyd urethane coating compositions containing 20 or 40 wt% (on solids) of partially solvolyzed waste polyurethane foam (PUR) were prepared and analyzed. Partial solvolysis of the soft polyurethane foam was carried out via extrusion with either 5 or 10 wt parts of solid polyol, that is, trimethylolpropane (TMP) or tris(hydroxymethyl)aminomethane. The addition of a partially solvolyzed PUR significantly affected the properties of cured coats, such as adhesion to a steel substrate, hardness, abrasion resistance, indentation depth, water absorption, tensile strength, and thermal stability. Moreover, the viscosity of ready-to-use coating compositions (containing a diisocyanate hardener) depended on a type and content of the processed PUR. Generally, a set of the most positively upgraded properties (viscosity, hardness, tensile strength, and thermal stability) was observed for coating compositions containing 20 wt% of PUR extruded with a higher dose of TMP (i.e., 10 wt parts of TMP/100 wt parts of waste polyurethane foam).
