You might be looking for a “conformal coating” and/or “potting compound“.
Conformal coating material is a thin polymeric film which conforms to the contours of a printed circuit board to protect the board’s components. Typically applied at 25-250 μm1 thickness, it is applied to electronic circuitry to protect against umidade, poeira, produtos químicos, e temperature extremes.
In electronics, potting is a process of filling a complete electronic assembly with a solid or gelatinous compound for high voltage assemblies by excluding gaseous phenomena such as corona discharge, for resistance to shock e vibração, and for the exclusion of water, umidade, or corrosive agents.
