- Coating Process
- Surface Preparation and Priming - The most important steps in a successful coating process are cleaning, pretreatment and priming. The following is a brief outline of some basics for unpainted substrates. It is not intended to be all-inclusive.
- Cleaning the substrate - All surfaces to be coated, must be free of dirt, grease, oil, oxidation, mill scale, and all other contaminants. The surface must be thoroughly dry before painting. Air quality regulations have limited the allowable emissions from cleaning operations.
- Aluminum - Cardinal’s 4860 Series pretreatment primers are to be used when an aluminum chemical conversion coating is not possible.
- Galvanized - Cardinal’s W-303-A surface preparation solution helps improve adhesion followed by a vinyl acid wash pretreatment primer such as Cardinal’s 4860 Series primer.
- Magnesium Alloy - Cardinal’s 4860- Series pretreatment primers are to be used when an Aluminum chemical conversion coating is not possible.
- Stainless Steel - White metal blast cleaning per SSPC-SP 7 / NACE No.1 to a uniform profile of 1.5 mils. Cardinal’s W-303-A surface preparation solution can help improve adhesion followed by a vinyl acid etching pretreatment primer such as 4860 Series.
- Coverage
- At 0.5 - 1.0 mil DFT (Dry Film Thickness), 65% transfer efficiency (TE)
- Mixed paint - 3.5 lbs/gal : 112 ft2/gal.
- Calculation: 1604 ft2/gal x % volume solids x (TE ÷ DFT)
- Application
All types of conventional spray equipment or HVLP may be used. A dry film of 0.5 - 1.0 mil must be applied, at this film thickness a transparent coating will be produced. Heavier film thickness will be detrimental to the complete coating system.
- Mixing
Two components must be mixed properly to obtain coating performance.

* for solventborne topcoats
** for waterborne topcoats
- Application Equipment
Most air quality regulations require the paint application transfer efficiency to be 65% or better. This can be accomplished by using HVLP spray guns; otherwise, conventional pressure feed, airless or air assisted airless spray equipment can be used. Air supply lines need water and oil traps.
- Equipment Cleanup
Clean up should be done as soon as possible keeping in mind the pot life of the mixed paint. Air quality regulations have limited the allowable emissions from cleaning operations. Strong solvents such as acetone provide adequate cleaning.
- Product Limitations
- This product is designed for adhesion promotion only.
- De-lamination may occur at a higher film thickness.
- Do not store mixed material in contact with metal containers.
