Paint Solids -Reply
There is no single right answer to this question. It really depends
on what the norm for a particular type of coating or particular end
use is. For example, there would be a difference in solids content
between a "high solids" automotive production clearcoat (maybe
50-60 weight percent solids) and a "high solids" automotive plastic
part adhesion promoter (perhaps 10-15 weight percent solids
because it needs to be applied at only a few tenths of a mil dry film
In some early California (SCAQMD) rules, high solids was defined
as more than 80 percent volume solids. This was a very high
We (EPA) have often used the term "higher solids coating " to
mean a coating (usually solvent-borne) with more solids than
"conventional" coatings. It's really just an identifier for lower VOC
content solvent-borne coatings to go along with other types of lower
VOC content coatings such as waterborne, powder, radiation cured
(uv cure and eb cure), etc.

What % by weight would be considered a high solids coating?
