Nano-waterproof protective coating is a kind of macromolecule polymer which is formed after deposition and polymerization on the surface of circuit module from small active free-radical molecular organic monomer. Small gaseous molecule can penetrate and deposit on the surface of the base material including any small gap under the mount. It has no small molecule such as additives and solvents, so it will not damage the base material and the protective layer with uniform thickness and excellent performance can provide very reliable protection for the surface of circuit components. Even the surface insulation resistance will not change after salt spray, acid-alkali, and durability tests and the thinner coating will not damage the heat dissipation of components.
