Spraying
- Shake the can vigorously.
- Spray a test pattern to ensure good flow quality.
- At an approximate distance of 20–25 cm (8–10 in), tilt the board 45° from a vertical position and spray a thin and even coat. Use spray-and-release strokes with an even motion to avoid excess paint in one spot. Start and end each stroke off the surface.
- Wait 5 min before applying another coat to avoid trapping solvent.
- Rotate the board 90° and spray again to ensure good coverage.
- Apply other coats until desired thickness is achieved (go to step 3).
- Let dry for 5 min at room temperature before heat cure.
Clearing nozzle between use
- Invert the can upside down.
- Use a foam or roller brush to coat the board. Use long, smooth strokes to create an even coat.

Technical Details & Test Data
- Compatibility
Chemical resistance - The thermoplastic resin is dissolved by common paint solvents like toluene, xylene, acetone and MEK. This allows for easy repair and rework of the coating, but makes it unsuitable for use in solvent-rich environments.
Adhesion - The coating adheres to most plastics and metals used to house printed circuit assemblies; however, it is not compatible with contaminants like water, oil, or greasy flux residues that may affect adhesion. If contamination is present, first clean the surface to be coated with MG Chemicals 824 Isopropyl alcohol.Substrate Adhesion
Substrate Note Acrylonitrile Butadiene Styrene (ABS) Chemically etches a) and adheres well. Polyvinyl Acetate (PVA) Chemically etches a) and adheres well. Polyvinyl Chloride (PVC) Chemically etches a) and adheres well. Polyamide (Nylon 66) Chemically etches a) and adheres well. Acrylics or Acrylic Paints Adheres well to clean surfaces. Epoxy, FR4 substrate Adheres well to clean surfaces. Polyurethane Adheres well to clean surfaces for most urethane types.
Wood Adheres well with surface preparation. Brass Adheres well with surface preparation. Copper Adheres well with surface preparation. Aluminum Adheres well with surface preparation. - a) Etching is similar to sanding, except that it softens the surface helping the paint adhere to the plastic.
