Conformal Coating Materials

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.
