MG Chemicals Conformal Coatings

Conformal coatings supplied by MG Chemicals are thin film protective coatings applied typically between 25-150µm in thickness. A conformal coating is a protective non conductive dielectric layer that is applied onto the printed circuit board assembly to protect the electronic assembly from damage due to contamination, salt spray, moisture, fungus, dust and corrosion caused by harsh or extreme environments.

Conformal Coatings from MG include
419D Acrylic Conformal Coating
UL pending high performance solvent based acrylic conformal coating.
4223D Polyurethane Conformal Coating
UL pending high performance solvent based polyurethane conformal coating.
422B Silicone Conformal Coating
Flexible finish solvent based silicone conformal coating that provides a high temperature, water repellent protective finish for printed circuit boards against moisture, corrosion, and thermal shock.

Why use Conformal Coatings?

Conformal Coatings are usually used on electronic products that are exposed to adverse environments where heat, chemicals and / or moisture are prevalent. Coating also can prevent damage from rough handling, installation, reduction of mechanical and thermal stress. It can prolong the life of the product during its operation and at the same time, it can help to increase the dielectric strength between conductors enabling the design of the PCB to be more compact and small. Finally, it also acts to protect circuitry and components from abrasion and solvents.
When coated, it is clearly visible as a clear and shiny material. Some coatings are hard, while others have a slightly rubbery texture. Most coatings include a marker that appears greenish white when view under UV light. This marker enables easy inspection of the coating thoroughness checking during production.

Market Sectors for Conformal Coatings

The range of products that are conformal coated in the electronics world is enormous and includes applications in the military, telecommunications, transport including marine, automotive, rail and aerospace, industrial processes, medical and any other electronic system that requires protection from contamination, salt spray, moisture, fungus, dust and corrosion caused by harsh or extreme environments.
