Application Procedure
1.	Flush all equipment with thinner or Amercoat 12 before use.
2.	Stir base using an explosion-proof power mixer to disperse pigments.
3.	Add cure to resin. Mix thoroughly until uniformly blended to a workable consistency. Induction time 70°F/21°C   15 minutes
4.	Do not mix more material than can be used within the expected pot life, 41.2 hours at 70° F.
5.	For optimum application, material should be from 50° to 90° F (10° to 32° C).
6.	Use only PPG recommended thinners at 1 pint/gal. Below 50°F additional thinning may be needed and multiple coats required to achieve specified thickness.
7.	To minimize orange peel appearance, adjust conventional spray equipment to obtain adequate atomization at lowest air pressure.
8.	Apply a wet coat in even, parallel passes with 50 percent overlap to avoid holidays, bare areas and pinholes. If required, cross spray at right angles.
9.	When applying directly over inorganic zincs or zinc-rich primers, a mist coat/full coat technique may be required to minimize bubbling. This will depend on the age of the Dimetcote, surface roughness and conditions during curing.
10.	Ventilate confined areas with clean air between coats and while curing the final coat. Prevent moisture condensation on the surface between coats.
11.	Repair damaged areas by brush or spray.
12.	Clean equipment with thinner or Amercoat 12 immediately after use.
Note: Consult Code of Federal Regulations Title 29, Labor, parts 1910 and1915 concerning occupational safety and health standards and regulations, as well as any other applicable federal, state and local regulations on safe practices in coating operations
