a.Reduce smog-forming emissions and protect air quality
b.Increase the gloss of paint

VOCs contribute to ground-level ozone (smog), so California, through CARB and local air districts, limits the VOC content of architectural coatings. Painters must select compliant low-VOC products in regulated categories. These rules affect which coatings and thinners can legally be used.
