Raven Lining - Model 400 -Ultra High Build Epoxy Coating
Raven 400 ultra high build epoxy coating is a 100% solids, solvent-free formulation that provides excellent protection against concentrated acids such as 98% sulfuric acid in immersion service. Raven 400 has superior adhesion strength to concrete, steel, masonry and other surfaces.
Typical Uses
Surfaces where protection from highly concentrated acids and severe caustics is desired, including:
- Tanks and troughs
- Pipelines
- Secondary containment
- Equipment
- Sumps and wet wells
- Industrial Manholes
- General maintenance
- Floors and walls
Color
The Part A Resin is white; the Part B Curing Agent is green. When mixed the product is light green. Limited special colors are available on request.
Solids By Volume
- 100% solids by volume
- Volatile Organic Compounds: 0.0 pounds per gallon
Film Thickness
Raven 400 is a 100% solids epoxy with zero shrinkage. Wet film thickness and dry film thickness are the same (i.e. 80 mils WFT = 80 mils DFT). Depending on substrate type and profile, a maximum of 125 mils per coat is recommended to prevent sagging. Recommended thickness will vary from 40 250 mils+ based on service conditions.
Coverage
Theoretical coverage is 40 square feet per gallon at 40 mils wet film thickness. Actual surface coverage will depend on substrate porosity and roughness. Good painting practices suggest application of two coats for quality assurance. A wet film thickness gauge may be used to determine actual coating coverage.
Application
Apply with brush, roller, airless or air-assisted spray or other suitable method. Optimal proportioning and mixing is achieved with the use of an RLS approved plural component airless spray system. For best results, apply this product to concrete when its temperature is stable or falling.
