MG Chemicals 8309-P, Conformal Coating Remover Pen, 0.33oz Pen, Case of 5 Pens
MG Chemicals 8309-P — Conformal Coating Remover Pen, 0.33oz, Case of 5
The MG Chemicals 8309-P (SKU: 8309-P) is a liquid conformal coating remover in a convenient pen applicator format. It removes most reworkable conformal coatings including thermoplastic (non-cross-linked) acrylics, polyurethanes, and silicone-based conformal coatings from PCBs. The pen format enables precise spot removal for PCB maintenance, rework, and repair without affecting surrounding components or coating. Also effective for removing conductive ink lacquers. Biodegradable, SVHC-free, and safe on most PCB components and metals. Sold in cases of 5 pens.

Frequently Asked Questions
What conformal coatings does the 8309-P remove?
The 8309-P removes most reworkable (thermoplastic, non-cross-linked) conformal coatings including acrylics, polyurethanes, and silicone-based coatings. It is not designed for fully cured epoxy conformal coatings, which are thermoset and generally require mechanical removal. Check the MG Chemicals TDS to confirm compatibility with your specific coating before use.
Is the 8309-P safe to use on populated PCBs?
Yes — the 8309-P is formulated to be safe on most PCB components and metals, making it suitable for spot removal directly on populated boards during rework and repair. As with any chemical, test on a small area first if working with sensitive or unfamiliar components.
How does the pen applicator work?
The 8309-P pen has a felt tip applicator that delivers the liquid stripper directly to the coating area. Apply the tip to the coating, allow the stripper to penetrate and soften the coating, then wipe or brush away the dissolved residue. Repeat as needed for thicker coating deposits.
What is the difference between the 8309-P pen and the 8309 liquid stripper?
The 8309-P is the same formulation as the MG Chemicals 8309 conformal coating stripper but packaged in a pen applicator for precision spot removal. The 8309 liquid is available in larger formats (850ml bottle, etc.) for bulk stripping or automated processes. The pen is ideal for rework and repair; the liquid is better for production-scale stripping.
Is the 8309-P biodegradable?
Yes — the 8309-P is fully biodegradable and environmentally safe. It contains no SVHCs (Substances of Very High Concern) as defined by REACH regulations, making it a more environmentally responsible choice compared to solvent-based strippers.
