Why PCBs in the USA Need Conformal Coating
Field conditions across the USA vary widely: humid Gulf Coast summers in Texas and Florida, salt air on both coasts, freezing winters in the Midwest and Northeast, and hot, dusty deserts in Arizona and Nevada. Temperature swings cause condensation inside enclosures, which is a common cause of PCB failures. A conformal coating keeps moisture, salt and dust off the circuit and protects against leakage currents and corrosion.
What Acrylcoat protects against
- Moisture, humidity and condensation
- Oxidation and corrosion of component leads
- Fungus growth in humid conditions
- Dust and contamination between conductors
- High-voltage arcing and corona shorts

How to Apply Acrylcoat Conformal Coating
- Clean the boardRemove flux, oil and dust with Elclean Liquid or ELCLEAN E-Clean.
- Pre-heatWarm the PCB to about 45–50°C in an oven or with a hot-air blower to drive off moisture.
- ApplySpray evenly from about 25 cm, or brush or dip. For volume work use our spray pump.
- Dry & cureAR grades are touch dry in about 10–15 minutes; ALQ-60, ALQ-100 and SKR-70 are oven cured at 80°C.
- InspectCheck coverage under a UV lamp on grades with a UV tracer before testing.
Exact drying and curing times depend on the grade and film thickness. See each product page or the technical data sheet for details.
