About MG Chemicals 419E Premium Acrylic Conformal Coating
MG Chemicals 419E is a one-part, UL 746E certified, acrylic conformal coating. It cures to a durable, flexible and smooth finish. It is easy to apply and can be handled in 15 minutes. It may be removed with appropriate strippers, or soldered through for repair or rework. 419E creates a robust moisture barrier that protects printed circuit boards in humid environments. It provides strong protection against moisture, corrosion, dirt, dust, thermal shock, short circuits, high-voltage arcing, and static discharge. Application instruction: Spraying: 1. Dilute coating with 4352 Thinner 2. Adjust ratio if required. 2. Stir the coating gently but thoroughly. 3. Spray a test pattern to ensure good flow quality. 4. 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. 5. Wait 6 min before applying another coat to avoid trapping solvent. 6. Rotate the board 90° and spray again to ensure good coverage. 7. Apply other coats until desired thickness is achieved (go to step 3). 8. Let dry for 6 min at room temperature before heat cure. Touch up by brushing: 1. Stir the coating gently but thoroughly. 2. Use a brush apply a small amount to touch up. Dip coating: Use a Ford or Zahn cup to monitor the viscosity of the coating as the solvent will evaporate over time. 1. Hang the PCB on a dipping arm. 2. Slowly lower the PCB into a tank and leave immersed in the coating for 2 min to allow penetration. 3. Slowly withdraw the PCB from the tank at an approximate rate of 6"/min. 4. Let dry to tack free finish before applying additional coats or heat cure. Selective coating: Custom blended solutions are available and have been verified for use with selective coating machines using both non-atomized and film coating applicators. To inquire about a custom solution tailored to your equipment, contact MG Chemicals’ Technical Support for assistance. Cure Instructions Room temperature cure: Let cure at room temperature for 24 h. Heat cure: Put in oven at 65 °C [149 °F] for 30 min. —OR— Put in oven at 80 °C [176 °F] for 15 min. —OR— Put in oven at 100 °C [212 °F] for 5 min.
