Form RC-BC Release Chart

Form RC-BC is an all black release chart. Overall dimensions of 7-5/8 x 10-1/4 in (194 x 260 mm).

The spreading rate (H) and wet film thickness (T) can then be calculated from the following simple relationships:

H (m²/L) = A (cm²)·N·D (kg/L)/10 M(g)

H (ft²/gal) = 40.746 H (m²/L)

H (ft²/gal) x T (mils) = 1604.2

H = spreading rate (m²/L), (ft²/gal).
T = wet film thickness (µm), (mils)
A = test area (cm²)
D = paint density (kg/L)
M = dry film weight (g)
N = non-volatile fraction by weight of the applied paint
