Beschreibung
Zusammenfassung:	Disclosed is a modified acrylic coating composition cured with melamine characterized by improved impact resistance which comprises: An acrylic polyol dissolved in a suitable solvent to 40-90% solids; 2 to 50% by weight of said acrylic polyol substituted with a polytrimethylene carbonate polyol selected from a polytrimethylene carbonate diol, a polytrimethylene carbonate triol, or a higher functionality polytrimethylene carbonate polyol; a melamine crosslinking agent; optionally a catalyst; and optionally pigments and other additives commonly used in coatings. Also disclosed in a related embodiment is a melamine/urea formaldehyde polytrimethylene carbonate coating composition that is prepared without acrylic.
