Application Procedure
Amercoat 370 is packaged in two components in the proper proportions which must be mixed together before use.
1. Flush equipment with thinner or Amercoat 12 before use.
2. Stir each component thoroughly, then combine and mix until uniform.
3. For general use, if thinning is necessary for workability, add Amercoat 65 below 60°F or Amercoat 101 at 60°F and above. Thin in quantities up to 1 pint per gallon of Amercoat 370. For potable water tank lining applications, see current NSF listing at www.nsf.org for approved thinner and thinning restrictions.
4. Do not mix more material than will be used within 4 hours at 70°F (21°C). Pot life is shortened by higher temperatures. Thinning may be necessary for workability periodically throughout pot life.

Application Equipment
The following is a guide; suitable equipment from other manufacturers may be used. Changes in pressure, hose and tip size may be needed for proper spray characteristics.
Airless spray - Standard equipment such as Graco Bulldog Hydra-Spray or larger with a 0.015- to 0.021-inch (0.38mm to 0.53mm) fluid tip.
Conventional spray - Industrial equipment, such as DeVilbiss,MBC or JGA gunwith 78 or 765 air can and "E" fluid tip, or Binks No. 18 or 62 gunwith a 66x63PB nozzle set up. Separate air and fluid pressure regulators,mechanical pot agitator, and amoisture and oil trap in themain air supply line are recommended.
