Waterborne coatings considered zero VOC

Waterborne coatings considered zero VOC

Why aren’t all waterborne coatings considered zero VOC (volatile organic content)?

Although they are more environmentally-friendly alternatives compared to many solventborne coatings, most waterborne acrylic coatings do contain some volatile organic compounds, and thus are not zero VOC. The organic compounds often enter the paint formulation from co-solvents called coalescents, which are necessary to soften the acrylic polymer particles so that they can fuse together as the film dries.
Many additives such as defoamers, pigment dispersants and wetting agents also contribute low levels of volatile organic compounds.
