Products & Materials第 39 / 100 题
If a coating is applied at 4 mils wet and the paint is 50% solids by volume, what is the approximate dry film thickness?
a.4 mils
b.2 mils
c.8 mils
d.1 mil
解析
Dry film thickness equals wet film thickness times the percent solids by volume: 4 mils x 0.50 = 2 mils dry. The solvent portion evaporates, leaving only the solids as the dry film. Knowing solids content lets a painter target the specified dry mil thickness.
