This allows a biobased content of 34-68% for current commercially available products designed for various end uses. Providing these polymers as a latex or dispersion in water allows for formulations at VOC content well below the lowest established AIM limits worldwide. That these unsaturated oils crosslink to form thermoset films provides a level of performance that easily competes with thermoplastic fossil fuel-based binders. In addition to the low VOC and desirable performance, these polymers can be used in coatings that are favored in government purchases through the USDA BioPreferred' Program. They enjoy the marketing advantage of displaying the USDA Certified Biobased Product label.

VerreIndex. décimale : 667.9 Revêtements et enduits Résumé : In this study, all of the white paints generally exhibit industry acceptable initial solar reflectance index values,2 and thus offer varying degrees of potential savings over a black roof baseline. Paints made with glass bubbles offered the highest degree of potential energy savings based on the fillers studied in this experiment. This study does not take into account the other parameters that qualify an acceptable elastomeric roof coating such as elongation, water resistance, etc. Final formulations need to be tested for ail specified properties to determine final acceptante per customer specifications. New studies have suggested maintaining certain minimum SRI values after actual outdoor weathering intervals. These and other studies such as the impact of glass bubbles on the solar reflectance of colored paints may form the basis for future studies. The white elastomeric paints in this study target low sloped roofs such as those utilized in industrial applications. Higher sloped roofs using other colors for residential applications could potentially benefit from these same materials.
White elastomeric waterborne acrylic roof coatings made with glass bubbles can offer formulators an alternative to other conventional fillers used in these coatings. The smaller glass bubbles offer increased solar reflectance and thermal advantages, which in turn could result in energy savings. The smaller bubbles also offer higher strength which could be beneficial for higher pressure applications such as airless spraying. In addition, the smaller bubbles yield a smoother appearance and good dirt pick-up resistance. The magnitude of these benefits needs to be evaluated by each formulator for their particular application and formulation.Note de contenu : - Opacity, gloss, and thickness

Revêtements antisalissures:Peinture antisalissuresIndex. décimale : 667.9 Revêtements et enduits Résumé : "Biofouling control has tremendous environmental benefits that range from energy savings to slowing the spread of invasive species. Over regulating copper-based antifouling coatings - the most proven and utilized (marine) coatings in the world, which have been universally approved by numerous countries worldwide based on the results of exhaustive human health and environmental studies - is questionable".
