Conformal Coating Brushes for PCB Coating & Touch-Up (Pointed Rounds)

We use these conformal coating brushes in our own production environments. Our team — and many of our customers — have relied on them for years in professional electronics coating workflows.

The brushes are tapered to a fine point to support precise manual application of conformal coatings. Operators use them for hand coating PCBs, touch-up work, and rework tasks, particularly in areas where control and accuracy are critical.

In practical use, brushes are rarely used in isolation. They form part of a controlled bench process, typically alongside small-volume dispensing containers such as 30ml or 60ml conformal coating jars. These allow operators to control coating volumes, reduce exposure to air, and minimise contamination during repeated dipping.

They are especially effective around components, edges, small pads, vias, and tight spaces — helping technicians apply coating smoothly while reducing streaking and limiting pooling.

Why choose these brushes?

• Fine, tapered tips for accurate detail work
• Maintain their shape during repeated use
• Flexible bristles that resist shedding
• Consistent performance during prolonged dipping
• Suitable for prototypes, touch-ups, and low-volume production
• Designed for professional electronics manufacturing

Typical conformal coating workflow

For controlled manual coating and rework, operators typically use a simple, repeatable setup:

• Dispense coating into a jar – use a 30ml jar for precision work or a 60ml jar for extended use
• Apply coating with a brush – controlled pickup and placement reduces excess material and improves finish quality
• Control and correct coating – use polyester swabs with suitable solvents to remove excess coating, refine edges, and re-bond lifted conformal coating areas

This approach supports consistent application, controlled material usage, and repeatable results during both initial coating and rework operations.

Choosing the right setup

• 30ml jar: best for precision work, small batches, and rework
• 60ml jar: better for extended use and higher material volumes
• Brush size: smaller sizes for fine detail, larger sizes for coverage

Most operators keep multiple jar sizes available to match different stages of the coating process.

Looking to coat larger, flat areas more quickly?

For wider, smoother laydown over flat PCB regions, solder masks, and open board areas, many operators prefer our chisel-tip coating brushes. These spread coating evenly over larger surfaces, whereas the pointed brushes above are optimised for precision and detail.

Brush sizes and dimensions

The table below shows key dimensions for brush sizes 1–6. The tip diameter indicates how fine the point is for detail work, while the length gives an indication of reach and control.

All dimensions are shown in millimetres.
