Viscosity Guidelines

Epoxy Viscosity Similar in
Cps Consistency to
1 = Water
500 = #10 Motor Oil
2,500 = Pancake Syrup
10,000 = Honey
25,000 = Chocolate Syrup
50,000 = Catsup
250,000 = Peanut Butter
1,000,000 = Paste-Caulking Material

Pot Life (working Time) of Epoxy Coating:

Typically an 8mC ( 18mF ) increase in temperature will reduce the pot life and cure time in half. Likewise, a similar drop in temperature will double the pot life and cure time for most epoxies.

Coating Coverage Calculation

The coverage rate required for a particular job can be obtained by dividing 1604 by the mil thickness specified:
Square feet/gallon coverage = (1604) / (mil thickness specified)

Or

Wet Film Thickness required = (1604) / sq. ft. per gallon

(example: A 12 mil thickness coating specification would require placement at 134 sq. ft./gal.)

Assuming the solids content of the coating in the example above is 35%, the dry film thickness would be reduced from 12 mils to 4.2 mils:

Dry Film Thickness = (Wet Film Thickness) x (% Solids) / (100)
