Fundamentals of Corrosion
TabLE 7.14
Multilayer Paint Systems Requiring That Surface Be Abrasive Blasted in
Accordance with SSPC-SP-10 Near-White Blast
System A Aluminum-Epoxy Mastic/Aluminum-Epoxy Mastic
Paint Layers:
One coat aluminum-epoxy mastic: 4–6 mil dft (100–150 μm)
One coat aluminum-epoxy mastic: 4–6 mil dft (100–150 μm)
Properties:
Tolerates poorly prepared surfaces and provides excellent barrier protection
A third coat may be added for additional protection
Can be used on carbon steel and concrete
Concrete must be clean, rough, and cured at least 28 days
If necessary, this system can be applied to surfaces that are pitted or cannot be blasted, but
the service life will be reduced
System B Epoxy Phenolic Primer/Epoxy Phenolic Finish/Epoxy Phenolic Finish
Paint Layers:
One coat epoxy phenolic primer: 8 mil dft (200 μm)
One coat epoxy phenolic finish: 8 mil dft (200 μm)
One coat epoxy phenolic finish: 8 mil dft (200 μm)
Properties:
Because of this system’s outstanding chemical resistance, it is often used in areas subject to
frequent chemical spills
The finish coats are available in a limited number of colors
Normally used on carbon steel and concrete. Concrete must be clean, rough, and cured at
least 28 days
System C Epoxy Phenolic Primer/Epoxy Phenolic Lining/ Epoxy Phenolic Lining
Paint Layers:
One coat epoxy phenolic primer: 8 mil dft (200 μm)
One coat epoxy phenolic lining: 8 mil dft (200 μm)
One coat epoxy phenolic lining: 8 mil dft (200 μm)
Properties:
Because of this system’s overall chemical resistance, it is suitable for lining areas subject to
flowing or constant immersion in a variety of chemicals
Normally used on carbon steel and concrete
When used on concrete, the surface must be clean, rough, and cured at least 28 days
System D Epoxy/Epoxy
Paint Layers:
One coat epoxy: 4–6 mil dft (100–150 μm)
One coat epoxy: 4–6 mil dft (100–150 μm)
