摘要:
The present disclosure is directed to a low VOC (volatile organic content) waterborne coating composition comprising low molecular weight polytrimethylene ether glycol. This disclosure is further directed to an antimicrobial coating layer formed from the coating composition comprising low molecular weight polytrimethylene ether glycol. The coating compositions can be used as interior and exterior top coats, basecoats, primers, primer surfacers and primer fillers. The low molecular weight polytrimethylene ether glycol can also be functioning as a coalescing agent. The disclosure is particularly directed to a coating composition comprising components derived from renewable resources.

摘要:
The present disclosure relates to a sag control composition consisting essentially of the reaction product of an amine and a polyisocyanate and polytrimethylene ether diol. The sag control composition can be used for providing further compositions that have excellent sag resistance, especially on vertical surfaces. The sag control composition can also provide compositions having a relatively lower content of organic solvent when compared to previously known sag control compositions.

摘要:
The present invention is directed to a process for process for predicting gloss of a coating resulting from a wet layer of a low gloss coating composition, such as automotive OEM or refinish paint. The process includes measuring reflectance of the layer of the coating composition applied over a test substrate and then allowing the layer to dry and/or cure into a coating. Thereafter, its gloss is measured with a gloss meter. The process is repeated with varying amounts of one or flatting agents added to the composition and the reflectance vs. gloss is plotted on a graph and by using a curve fitting equation a gloss prediction curve is obtained. By measuring the reflectance of a wet layer of a target low gloss coating composition the gloss of a coating that would result from such a layer is then predicted by using the gloss prediction curve. The process is most useful during the manufacture of coating compositions, such as automotive OEM and refinishes paints.
