Corrosion of Paint
245
TabLE 7.13 (continued)
Multilayer Paint Systems Requiring Commercial Blast (SSPC-SP-6) for Surface
Preparation
Properties:
An easily applied two coat high build barrier protection is provided with ease of application
Used on carbon steel or concrete
Limitations
Because these are two-component materials, they must be mixed just prior to application
They require additional equipment and more expertise to apply than a single-packed product
Many epoxy finish coats will chalk, fade, and yellow when exposed to sunlight
System Η Epoxy Primer
Paint layers:
One coat epoxy primer: 4–6 mil dft (100–150 μm)
Properties:
Normally applied to carbon steel or concrete in protected areas such as the interiors of
structures, behind walls and ceilings, or for temporary protection during construction
Limitations:
This is a two-component material requiring mixing just prior to application
System I Epoxy Novalac/Epoxy Novalac
Paint Layers:
One coat epoxy novalac: 6–8 mil dft (150–200 μm)
One coat epoxy novalac: 6–8 mil dft (150–200 μm)
Properties:
An exceptional industrial coating for a wide range of chemical resistance and physical
abuse resistance
Has a higher temperature resistance than standard epoxy
May be used to protect insulated piping or for secondary containment
Normally used on carbon steel and concrete surfaces
