How is wet non-aqueous solvent suspended developer applied?

• A. Spray can after the drying process
• B. Before the drying process
• C. By brushing on the surface
• D. Dipping the part into the developer

Answer: (A)

Wet non-aqueous solvent suspended developer is used as a thin, uniform coating, and spraying achieves that best. Applying it after the surface is dried keeps the coating even, prevents dilution or smearing by residual moisture, and lets the volatile carrier evaporate quickly so a consistent film remains. A sprayABLE film also covers complex shapes smoothly without removing or redistributing penetrant, which can happen with brushing or immersion. Brushing tends to drag or accumulate material unevenly, and dipping would flood the part, creating an inconsistent layer.
