Dielectric Coating

Find dielectric coating to protect and insulate metal parts, circuits and tools
By Leah Kuriluk A dielectric coating generally consists of epoxy and is applied in two coats. This coating is usually applied to small metal parts, like transformer turns, semi conductor heat sinks, laser wave guides and circuit boards. Dielectric coatings are mainly used to insulate or protect parts in the electronics industry, and in glass coatings.

Oxide ceramics and polymers are two more of the most common dielectric coating types. Aluminum, yttrium and titanium oxides are also used on a regular basis. You can use other alloys, compounds and materials as a dielectric coating material, depending on the strength of the coating and the object. Before using a dielectric coating, consider this:

1. Although dielectric coatings are usually applied to metal, they can be used on most composites as well.

2. Some of the processes used to apply dielectric coatings may require extreme heat to provide a smooth application. This can warp or degrade some types of base materials.

3. Dielectric coatings can be used on glass to create a mirrored effect. This type of coating applies silver, aluminum or gold to a piece of glass to achieve the effect.

Purchase a dielectric coating for tools and medical supplies

Tools used in the electronics industry, and those used to perform certain medical procedures where electronic equipment is vital, are treated with a dielectric coating. This helps prevent accidental electrocution and other accidents. This type of coating can be applied in many different ways, but most involve exposure to extreme heat.

Get dielectric powder coatings on circuit boards and other electronics

Circuit boards, heat sinks and other electronic components sometimes require a dielectric coating to protect them from mold, abrasion, dust and corrosion. Coating circuit boards protects its delicate circuits, which increases the board's lifespan and reduces the chance of damage during repair.
Try:  Purchase dielectric finishing from Collt Manufacturing, or check out the different dielectric coating materials available from the Consolidated Coating Company.

Buy dielectric powder coating for lenses and other glass products

Dielectric coatings can be used to create mirrors and provide reflective finishes to lenses frequently used in precision optics industries and light research. These coatings are usually metal-based and can be applied with many different methods. Vacuum coating is often used to apply a metal dielectric coating, like aluminum to glass.
Try:  Check out the coatings available from Precision Glass & Optics, or ask Quantum Coating to help with your mirror coating requirements.

• Although most dielectric coating providers offer a selection of materials and provide them, you may save money by purchasing your own dielectric coating materials. This gives you a wider selection than what is available from the average coating service provider and allows you to purchase the materials at wholesale prices.
