of handling.
Solids: 90% ± 2% by weight; 81% ± 2% by volume.
INTENDED USE
As an industrial tank lining. Pot Life: Approximately 1 hour at 70°F. A slight decrease in film
build properties may be noted after 1½ to 2 hours.
TEMPERATURE RESISTANCE
Dry temperature basis is 350°F for short periods; 250°F continuous. Shelf Life: 24 months at 70°F.
Immersion temperatures depending on particular reagent.
Shipping Weight: Approximately 12.5 lbs./gallon.
COLORS White, Lt. Gray, Lt. Blue.
Mixing Ratio: 1 part of curing agent to 5 parts of coating material by
FILM THICKNESS PER COAT volume.
A 6 to 7 mil film is easily produced in one multi-pass spray coat.

will produce a 12 to 15 mil film for immersion service. (Glass Standard = 250 seconds); ASTM Method D4366-84.
DRYING TIME Thermal Shock: Unaffected 5 cycles, minus 70°F to plus 200°F.
Surface will normally be tack-free in 10 to 12 hours at 70°F. Curing
will take place in 5 days at 90°F, 7 days at 70°F or 14 days at 50°F. Gloss: 80 at 60°.
