HLD-CC99 Hulida PCB conformal coating

Conformal Coating is a specially formulated fine polymer composite coating material that forms a protective film after curing to protect printed circuit boards and related electronic components. The equipment is protected from environmental erosion, thereby enhancing and extending its service life and ensuring safety and reliability during use.

In real-world conditions, such as chemicals, vibration, high dust, salt, high humidity, and other environments, circuit boards may encounter issues such as corrosion, softening, deformation, mildew, etc., leading to circuit board failure.

Applied to the surface of the circuit board, Conformal Coating forms a three-proof protective layer (moisture-proof, salt-spray-proof, and mildew/rain-proof), while also providing insulation, dustproofing, mud resistance, corona resistance, corrosion resistance, acid and alkali resistance, vulcanization resistance, aging resistance, high and low temperature 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 circuit board reliability, increasing the safety factor, and ensuring the service life of the circuit board.

By chemical composition synthesis, it can be divided into six categories: acrylic, silicone, polyurethane, epoxy resin, nanometer, and water-based. Regarding curing methods, solvent-based curing, room-temperature curing, heat curing, and UV curing are available to choose from.
