Résumé : |
The Technical Committee of the New York Society for Coatings Technology investigated commercially available additives for their influence on the rheology of low volatile organic compounds (VOC) coatings. These rheology modifiers are important because coatings manufacturers must change their formulations in order to comply with government VOC regulations. The committee solicited samples of rheology modifiers from 15 commercial manufacturers. They were tested in both water and solvent-based low VOC coating systems. The committee received rheology modifiers from 14 generic types. Standard bake enamels using these rheology modifiers were prepared in water and solvent-based systems. The paints were considered for degree of sag, pigment suspension, sprayability, and specular gloss. Sprayability was evaluated and compared with three methods of viscosity determination for possible trend developments and predictions. |
