A New Concept in Moisture Protection for Circuits and Components

Condensation of atmospheric moisture on electrical circuits and components can have a dramatic adverse effect on both performance and physical state. If the assembly is not suitably protected against moisture ingress, reductions in performance can be expected that are due to shorting and/or corrosion of circuit elements and component leads. Many of the available resinous coatings contain 'active' residues which, in the presence of moisture, may themselves cause shorting and corrosion. A new coating material based on a non‐curing fluorochemical polymer gives excellent moisture and electrical protection and contains no active residues which might cause corrosion. It can be removed easily with solvents for ease of repair and component replacement.
