3 Conformal/4 Conformal/5 Conformal Coating

Packing unit: 1.0L/Can, 5.0L/Can

3 conformal coating refers to a type of low-viscosity fluid used to protect printed circuit boards and related electronic components from environmental erosion. According to the usage requirements of the region and manufacturer, "3 conformal coating" is often called covering adhesive, moisture-proof adhesive, insulating adhesive. It has the performances of moisture-proof, dust-proof, and chemical liquid-proof, and can improve the circuit board reliability.
