Conformal Coating

Protective coatings are necessary to ensure a long and effective working life of electrical and electronic components.

Petech has a range of three coatings available to protect circuit boards, windings and coils, stator windings, field coils, transformers and more.

These coatings suppress arching, and resist environmental and physical forces such as mould, fungus, water, solvents, scratching and static discharge.

This will be embraced by the many industries including mining, marine, sewage and the countless other industries that deal with harsh environments on a daily basis.

Petech can be apply these coatings to new and existing units. Please contact us here for more information

Acrylic Conformal Coating is a durable finish coating product that provides an all round protective coating against moisture, corrosion, and thermal shock. It protects and insulates electrical and electronic components and assemblies including generators, motors, transformers, relays and solenoid coils.

Silicone Conformal Coatings is a flexible finish that protects Printed Circuit Boards and related equipment against moisture, corrosion, thermal shock and vibration. It protects and insulates electrical and electronic components and assemblies including generators, motors, transformers, relays and solenoid coils.

Urethane Conformal Coating is a unique, high temperature electrical insulator that forms a tough, clear chemically resistant film. It conforms to military specification MIL-V-173C-2.
