Conformal Coatings

Browse this section to find the best Acrylic or Silicone conformal coating spray for your assembly requirements.  A selection of aerosols and 1 gallon pails is offered.

Conformal coating spray is a specialty polymeric film forming product that protects circuit boards, components, and other electronic devices from adverse environmental conditions. These acrylic & silicone conformal coatings ‘conform’ to the irregular landscape of the PCB providing increased dielectric resistance, operational integrity, and protection from corrosive atmospheres, humidity, heat, fungus, and airborne contamination such as dirt and dust.

Techspray offers a variety of conformal coating spray formulas to match field and engineering requirements and are IPC CC 830B, MIL-I-46058C, and UL94-0 Qualified or rated. Specifications generally depend on the type of protection needed: e.g. thermal, moisture, and 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, and the coated areas glow. The brighter the glow, the thicker the coating.
