At 100% solids by volume (SBV) a coating will cover 1604 square feet at 1 mil. This is usually rounded off to 1600 for simplification (see Table #1 Proof). By taking the require mil thickness and dividing it into 1600, you will get the square foot per gallon. For instance, let’s say the coating calls out to be 10 mils thick:
1600 ÷ 10 mil = 160 ’ per gallon
Let’s say you don’t have 100% solids, now what? Just give up. No, let’s take a product that is a 95% solid.
1600 (100% SBV) x 95% = 1520 (95% SBV)
Now take the (95% SBV) and plug it into the same formula
1520 ÷ 10 mil = 152 ’ per gallon
Table #1 Proof
1 gallon + 231 in³=
231 in³ = 231 ” @ 1000 mils
231 ” ÷ by 144 ” per ’ = 1.604 ’ @ 1000 mils
1.604 x 1000 = 1604 mils ’ per gallon
Symbol Key: ” = square inch
’ = square feet
in³ = cubed inches

ReplyDeleteThe width of a specific laminating film can vary due to the width of the base films master roll width.
For the best results, it is highly recommended to use a wide format laminating machine to in conjunction with your PSA film thickness.
