Questions about this product
- What is this insulating varnish actually used for on a circuit board?
- This varnish creates a clear, protective layer over a printed circuit board (PCB). Its main job is to stop moisture and humidity from getting to the components, which prevents oxidation and reduces the risk of short circuits.
- What size bottles does this come in?
- It's available in both 100ml and 250ml bottles. The clear formula allows you to apply a thin, efficient coat, so you can choose the size that best fits the scale of your electronics work.
- Will this coating make my PCB fully waterproof?
- It provides a strong moisture-resistant barrier that protects against damp environments and splashes. While it's very effective against humidity, it is not designed to make a board waterproof for full submersion.
