PCB Conformal Coating Wax is functional protective wax formulated for printed circuit boards. After molten application and cooling, it creates a thin, uniform conformal coating over PCB surfaces. This wax isolates circuit traces, solder joints and exposed components from humid air and corrosive contaminants, reducing the risk of short‑circuit and metal corrosion during PCB service and storage.

Product Detail

Product Overview PCB Conformal Coating Wax is dedicated conformal‑coating wax designed for printed circuit board protection. When heated into molten state, the wax exhibits appropriate fluidity. It can be applied by dipping, spraying or brushing onto assembled PCB. After cooling and solidification, it forms a thin, continuous conformal protective film that closely follows the uneven topography of circuit boards. The wax film seals solder joints, copper traces and exposed metal terminals. It blocks moisture, salt mist and fine particulate contaminants, slowing down metal oxidation and corrosion. It satisfies intermediate‑stage protection requirements for PCB manufacturing, transit and storage before final assembly.

Key Features ‑ Good molten fluidity to form thin, uniform conformal film following PCB surface contours ‑ Reliable moisture‑proof and anti‑corrosion performance for copper traces and solder joints ‑ Low‑ash formulation to minimize contamination risk for delicate electronic circuits ‑ Moderate adhesion without excessive residue when re‑processing is required ‑ Consistent physical properties suitable for manual and automated coating operations

Typical Technical Properties ‑ Chemical Type: Blended refined hydrocarbon‑based PCB protective wax ‑ Appearance: Off‑white to pale beige solid pastilles or flakes ‑ Melting Range: Refer to TDS ‑ Ash Content: Refer to TDS ‑ Water Absorption: Refer to TDS

Applications ‑ Intermediate PCB protection: Temporary conformal coating for finished printed circuit boards ‑ Electronic component assembly: Corrosion‑resistant surface protection for soldered joints ‑ PCB warehouse storage: Protective coating during work‑in‑progress inventory storage ‑ Industrial electronic manufacturing: Auxiliary protection for control‑board assemblies

Processing Recommendation Melt the coating wax under accurately controlled heating temperature and avoid thermal degradation. Ensure PCBs are completely dry and free of surface dust before coating. Allow adequate cooling and full solidification of wax film. Conduct small‑scale coating trials and electrical performance inspection prior to mass‑scale processing.

Storage & Handling Store in cool, dry, dust‑free warehouse away from heat sources. Reseal packaging right after opening. Wear protective gloves during handling of solid wax.
