All components of the Armor Flake 721 Lining system are catalyzed with Armor Plate 60, methyl ethyl ketone peroxide. The mixing ratio is 1.5 – 2.5 oz. of catalyst for each gallon of AF 721-1, AF 721-2, or AF 721-3. NEVER use more than 2.5 oz. of catalyst per gallon of Armor Flake 721 component.
Catalyzed Armor Flake 721 components have a short pot life. Mix only enough material to use during a short period. Inhibitor may be added to extend pot life if needed; consult with your Wil-Cor representative.
Begin the mixing process with 1 quart of AF 721-1, AF 721-2 or AF 721-3, and the proper proportion of catalyst. Measure the quantities of catalyst and component carefully, because only a small amount of catalyst is necessary for each quart of component.
After the catalyst and component are thoroughly mixed, remove the material from the mixing pot and quickly spray or roll over the surface. Catalyzed material will not set up as quickly if it is not concentrated in the pot. Immediately follow the initial spreading process with a thorough application procedure.
If the applied material does not set up within 3 to 4 hrs, the amount of catalyst in the mixture may be increased. DO NOT add more than 2.5 oz. of catalyst per gallon of component. If using a conventional pot, mix material prior to pouring into the paint pot. DO NOT mix MEKP in the paint pot.
