By applying it to a board or electronic component, it can improve electrical insulation, protection, water resistance, etc. Because it is a two-component, room temperature curing type, it can be used for heat-sensitive parts without requiring heating. The low viscosity makes it easy to work with and can be filled in every detail. It cures at the same time as room temperature even at low temperatures. Since the two-liquid does not cure quickly after mixing, you can work with plenty of time.
