Surface Preparation: Proper surface preparation is critical to the long-term performance of this product. The exact requirements for surface preparation vary with the severity of the application, expected service life, and the initial substrate conditions. Minimum preparation is mechanical preparation St2/St3. Optimum preparation will provide a surface thoroughly cleaned of all contaminants and roughened to an angular profile between 75-125 μm (3-5 mil). This is normally achieved by initial cleaning and degreasing and then abrasive blasting to a cleanliness of Near White Metal (Sa.21/2), followed by removal of residual abrasive blast residues from the surface to be coated.

Mixing: Mix the Activator thoroughly into the Base using the mixing rod, scraping the sides and bottom of the container. Mix by weight, 2 parts Base to 1 part Activator. Mix thoroughly to produce a uniform material without streaks. Never add solvents.

Application: Brush: medium to stiff bristle of sufficient quality that bristles do not pull out and stick in coating (epoxy glued bristles are best). Trim or tape to <1” nap. Roller: use good quality 1/8” nap. Airless Spray: 45:1 ratio or higher with a 529-535 trip, 5000 psi or higher. Temperature: 50°C (122°F). Plural-Component Airless: Graco XP70 or equivalent, heated to 43°C (109°F). Robotic Application: Robotic application of the coating on internal circumferential welds using a rotary atomizer. MixPac gun: 100 psi pressure, between 50 and 55°C (122 to 131°F).

Application Temperature: Keep between 55 to 95°F (17 to 35°C). Substrate: keep between 45 to 105°F (7 to 40°C). the difference in temperature of the substrate and the material should never exceed 10°F, 5°C. Substrate shall be a minimum of 5°F (3°C) above dew point. Do not apply if relative humidity exceeds 90%. If necessary, heat the metal prior to surface preparation using electric heater or heat lamp. Never use gas, oil or kerosene heaters as they will leave a greasy residue on metal surface. For best results keep all material in warm area overnight (75°F+) for ease of mixing.

FDA Compliance: This product complies with FDA regulations, for direct food contact specifically FDA 21 CFR 175.300 and FDA 21 CFR 175.105.
