MG Chemicals 419D-4L, Acrylic Conformal Coating, 1 Gallon Can, Case of 1
MG Chemicals 419D-4L, Acrylic Conformal Coating, 1 Gallon Can
MG Chemicals 419D is a fast-drying, one-part acrylic conformal coating that cures to a durable, flexible, and smooth clear finish. Tack-free in approximately 10 minutes, it creates a robust moisture barrier protecting printed circuit boards from humidity, condensation, corrosion, fungus, dirt, dust, thermal shock, high-voltage arcing, and static discharge. UL 94 V-0 certified and IPC-CC-830B approved. UV fluorescent for easy automated inspection. Validated for selective robotic coating equipment including PVA and Nordson ASYMTEK.

Frequently Asked Questions
How quickly can 419D be handled after application?
419D is tack-free in approximately 10 minutes at room temperature, allowing boards to be handled quickly after coating. Full dry time is 30 minutes at 65°C (149°F), or longer at room temperature. Refer to the TDS for full cure schedule details.
Can 419D be soldered through for rework?
Yes — 419D can be soldered through directly for component rework and repair without requiring full coating removal. It can also be fully removed using MG Chemicals 435 Thinner, 8309 liquid remover, or 8310A gel remover when complete removal is needed.
Is 419D compatible with automated selective coating equipment?
Yes — 419D has been validated for use with PVA and Nordson ASYMTEK selective robotic coating equipment, making it suitable for high-volume automated PCB coating lines.
Does 419D contain hazardous air pollutants (HAPs)?
No — 419D is formulated without toluene, xylene, or ozone-depleting compounds, making it compliant with HAP-free requirements in regulated manufacturing environments.
