When high reliability or long product life – or both – is the expectation, conformal coatings provide a robust protection solution. The materials safeguard against conditions that can cause electrical failures or voltage leaks, enabling the dependable performance of higher voltage, higher density electronics where miniaturization is a factor.
Browse our portfolio of conformal coating materials and discover which materials may be appropriate for your application.
Conformal coatings are polymeric materials applied to PCBs and sensitive components in a thin layer and cured to form a protective film. The coatings are insulating and resistant to moisture, dust, corrosion, and temperature extremes. Using conformal coatings can increase reliability and extend product life.
Conformal coatings help ensure the long-term performance and reliability of increasingly complex, component-dense, and miniaturized PCB assemblies. The materials protect PCBs within various environments where electronics can be exposed to chemicals, moisture, salt spray, and a wide temperature range. Without these coatings, electronics may corrode, experience voltage leaks, and otherwise degrade and fail prematurely.
Process flexibility
High-density PCB assembly protection
Meet product lifetime expectations
Conformal coating selection is determined by many factors, including end use, required UL certifications, and processing preferences. The materials are available in epoxy, polyurethane, acrylic, silicone, and other chemistries. They can be applied manually or automatically, and cured via heat, UV, or solvent evaporation.
