HLD-CC11 circuit protective coating Hulida

Conformal Coating is a specially formulated fine polymer composite coating material that forms a protective film after curing to protect circuit boards and related electronic components. The equipment is shielded from environmental erosion, thereby enhancing and extending its service life while ensuring safe and reliable operation.

In actual operating conditions—such as exposure to chemicals, vibration, high dust, salt spray, high humidity, and other harsh environments—circuit boards may experience issues like corrosion, softening, deformation, mildew, etc., leading to circuit board failure.

Applied to the surface of a circuit board, Conformal Coating forms a tri-proof protective layer (moisture-proof, salt-spray-proof, and mildew/rain-proof). At the same time, it provides insulation, dust-proofing, mud-proofing, corona resistance, corrosion resistance, acid and alkali resistance, anti-vulcanization, anti-aging, thermal shock resistance, high temperature and high humidity resistance, and other superior environmental protection properties. It effectively isolates the circuit board and protects the circuitry from erosion and damage in harsh environments, thereby improving PCB reliability, increasing the safety factor, and ensuring the service life of the circuit board.

Based on chemical composition, it can be divided into six categories: acrylic, silicone, polyurethane, epoxy resin, nano-coating, and water-based. Regarding curing methods, solvent-based curing, room-temperature curing, heat curing, and UV curing are available for selection.
