419D – Acrylic Conformal Coating

419D is a fast drying, acrylic based circuit board protective coating that cures to a durable, flexible and smooth finish. This 1-part circuit board coating is easy to apply and can be handled in 10 minutes. It can be readily removed with appropriate strippers, or soldered through for repair or rework.

  • Certified UL 94 V-0 (File # E203094)
  • Certified IPC-CC-830B
  • Super-fast cure – tack free in about 10 min; dries in 30 min at 65 °C [149 °F]
  • Protects circuit boards from moisture, corrosion, fungus, and static discharges
  • No hazardous air pollutants (HAPs) – free of toluene or xylene, free of ozone depleting compounds
  • Excellent finish – smooth, homogeneous and durable clear coat
  • Easy to inspect – fluoresces under UV light
  • Easy rework and repairs – removable with MG’s 435 Thinner, 8309 or 8310A conformal coating removers
  • Validated for selective robotic coating equipment including PVA and Nordson ASYMTEK

This circuit board coating creates a robust moisture barrier that protects printed circuit boards in humid environments. It strongly protects against moisture, condensation, humidity, corrosion, fungus, dirt, dust, thermal shock, short circuits, high-voltage arcing, and static discharge.

This product is also available in spray and pen formats.
