Steel
- Non-Immersion Service: Abrasive blast to a White Metal cleanliness according to SSPC-SP6 to achieve 1.5 - 3 mil anchor profile.
- Immersion Service: Abrasive blast to a White Metal cleanliness according to SSPC-SP5 to achieve 1.5 - 3 mil anchor profile.
- Application Equipment
Listed below are the general equipment guidelines for the application of this product.
- Conventional Sprayer - Industrial sprayers such as DeVilbiss MBC or JGA and Binks 18 or 62 having double regulated pressure pot, 3/8’ I.D. minimum material hose and a .070” I.D. fluid tip and air cap are recommended.
- Airless Sprayer - Sprayer such as Graco’s Extreme with a 60:1 ratio and a 0.017” - 0.021” tip is recommended. A 30 mesh inline filter is recommended
- Power Mixer - Use only explosion proof power mixers
- Brush or Roll - Use a medium brush and short nap roller with solvent resistant fibers and core. For small areas and touch-up only.
- Application Conditions
Material Surface Ambient Minimum 50˚F 50˚F 50˚F Maximum 90˚F 110˚F 110˚F Special reducing and application procedures are required outside these temperatures. Surface temperatures should be 5˚F above dew point to prevent condensation.
- Mixing & Reducing
- Mixing - Power mix each component, then blend Part B into the Part A and mix until uniform at the following ratio:
2 Gal. Kit 10 Gal. Kit M-250P Part A 1 gallon 5 gallon M-250P Part B 1 gallon 5 gallon - Reducing - Reducing is not required for most applications; however M-250P may be reduced up to 1 pint/gal. Reducer 1 - 250 is recommended for applications temperatures below 70°F and Reducer 2 - 250 is recommended above 70°F. Reducer 2-250 is recommended for overcoating inorganic zinc primers as well as for brush and roller applications of M-250P.
- Pot life - Four hours at 75°F. Less at higher temperatures.
- Clean Up
Cleanup with Reducer 3-400 or acetone.
- Dry & Cure Times
The following minimum times are based on a 10 mil DFT and adequate air ventilation. Higher thickness and reduced air circulation increase drying times.
Surface Temperature To Touch To Handle Final Cure 60˚F 16 hours 72 hours 14 days 75˚F 8 hours 36 hours 7 days 90˚F 4 hours 18 hours 4 days Elevated temperature final cure will increase the resistance of M-450EN. Product can be topcoated at “To Handle” time frame.
- Maximum Recoat
Surface Temperature Days 60˚F 14 70˚F 7 80˚F 4 90˚F 1 If the maximum recoat time is exceeded, the coating should be sweep blasted with fine aggregate to roughen surface.
