Conformal Coating & Encapsulation


The team at 4e have been applying conformal coatings for nearly 20 years in military, medical and aerospace products. Many of our clients require assemblies to have protection against external environmental extremes.

Conformal coating is a protective non-conductive chemical coating which can be applied to circuit boards. Its purpose is to protect the electronic circuits from damage due to contamination, salt spray, moisture, fungus, dust and corrosion caused by harsh or extreme environments.

By applying conformal coating, and electrically insulating your boards, it maintains long term surface insulation resistance (SIR) and ensures the integrity of your assemblies. Providing a barrier against contaminants and preventing corrosion. Coatings also help prevent damage from rough handling, installation, and reduction of mechanical and thermal stresses. It can also prolong the life of the product during its operation.
