All components of the Armor Flake 821 Lining System are catalyzed with Armor Plate 60, methyl ethyl ketone peroxide. The mixing ratio is 1.0-2.0 oz. of catalyst for each gallon of AF 821-1, AF 821-2, or AF 821-3. Use 1.0 – 1.5 oz. of catalyst per gallon at temperatures above 85° F. NEVER use more than 2.0 oz. of catalyst per gallon of Armor Flake 821 component.
Catalyzed Armor Flake 821 components have a short pot life (5 to 15 min.). Mix only enough material to use during a short period.
Begin the mixing process with 1 quart of AF 821-1, AF 821-2, or AF 821-3, 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 spread 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 hours, the amount of catalyst in the mixture may be increased. DO NOT add more than 2.0 oz. of catalyst per gallon of component.
