Conformal coatings are usually used in products that are made for use in outdoor environments where heat and moisture are prevalent. Coating also prevents damage from rough handling, installation, and reduction of mechanical and thermal stresses. It also prolongs the life of the product during its operation. At the same time, it helps to increase the dielectric strength between conductors enabling the design of the PCB to be more compact and small. It also acts to protect circuitry and components from abrasion and solvents
