Techspray FAQ: What Is A Conformal Coating?
A conformal coating is a thin layer of polymer applied to electronic components or circuit boards to protect them from environmental factors like moisture, dust, chemicals, and mild mechanical stress.
The goal of conformal coating is to increase durability and improve reliability of electronic devices, which will extend their life in harsh environments.
They are commonly used in various industries, including electronics, automotive, aerospace, medical electronics and many more.

PROTECT ELECTRONICS FROM EXTREME ENVIRONMENTS
Techspray offers SR, AR and UR conformal coating formulas for a wide variety engineering requirements including thermal, moisture & static resistance. All coatings are IPC-CC-830B and UL94 V-0 qualified.
Techspray offers a variety of conformal coating formulas for differing field or engineering requirements and is IPC CC 830B and UL94-0 Qualified or rated. Specifications generally depend on the type of protection needed: e.g., thermal, moisture, or static resistance.
Coatings contain Opti/Scan (except LED Coating) to allow quality control inspection of coverage and evenness of the coating on a PCB. A coated board can be passed under a standard, low-cost UV (short-wave black) light to fluoresce the coated areas. The brighter the glow, the thicker the coating.
Application methods:
Dip – High volume method to fully coat boards. Thickness of the final coating is controlled by viscosity and withdrawal speed from the pot.
Conformal Coating Spray – Computer controlled selective spray systems eliminate the need for masking. Higher viscosity is generally needed (70-200 cps) to create precise edge definition and prevent splattering.
Manual Application – Aerosol and brushing are generally used for small production runs, rework and repair. The aerosol needs to be compatible with the original coating if it’s rework.
