- Applications
- Cure Method
- Manual Spray Guns
Use a standard HVLP (High Volume Low Pressure) fluid nozzle gun with a minimum tip diameter of 1.2–1.4 mm. The settings listed below are recommendations; however, performance will vary with different brands:
LVMP HVLP Nozzle tip diameter 1.2–1.4 mm 1.2–1.4 mm Inlet pressure 5–15 psi 5–15 psi Air flow 10–15 SCFM 8.3 SCFM Air cap 5–10 psi 5–10 psi When using a pressure pot and agitator, keep the agitator at low mixing speed with air pressure of 20–50 psi. Use the lowest pressure necessary to keep the particles suspended.
- Brush
- Thinning is not required for most brush applications.
- Selective Coating
- For higher volume applications, paint can be applied via selective coating equipment. Use a system with constant fluid recirculation to keep the particles from settling in the lines. A fluid nozzle ranging from 1.2 mm–1.4 mm diameter and 5–10 psi fluid pressure is recommended depending on nozzle size. Thin the paint to adjust the viscosity to the level appropriate for the valve being used.
