Conformal Coating - Small investment for permanent protection.

- Protect electronic circuits from harsh environments that may contain high humidity, a range of airborne contaminants and varying temperatures.
- By being electrically insulating, it maintains long-term surface insulation resistance (SIR) levels and thus ensures the operational integrity of the assembly.
- It also provides a barrier to air-borne contaminants from the operating environment, such as salt-spray, thus preventing corrosion
