Conformal Coating
Conformal coating protects your PCBAs
Originally developed for military and aerospace applications, conformal coating is now widely used across many industries. Considered an essential for electronics operating in challenging environments, conformal coating provides protection against moisture and chemical exposure, reduces the effects of vibration, and minimises the risk of current leakage, improving the long-term reliability and performance of your products.
Active-PCB Solutions offers conformal coating from our high-spec facility within our Reading factory, which means we can protect your assembled PCBs as an integral part of the manufacturing process before they are dispatched. Using our in-house conformal coating facility allows us to maintain full control over the application, quality and traceability, while reducing the risks and lead times associated with subcontracting.
Our controlled processes ensure that every coated assembly meets the highest quality standards and is delivered to you ready for use.

Materials We Use
Our Rehm Protecto XP Selective Coater is a four-headed system, meaning we can apply up to four materials in a single process and no downtime when switching between coating types.
The materials we use in our in-house conformal coating facility are:
- Nanocoating: Ultra-thin and lightweight, waterproof to IPX7/IPX8, flexible and environmentally friendly protection for sensitive components. Does not require time consuming masking, making it a low cost option.
- Acrylic (1B31): Versatile, quick-drying protection with good moisture resistance and good dielectric properties. Can be re-worked.
- Urethane (1A33): Excellent chemical and mechanical resistance. Good moisture and humidity resistance.
We are also able to provide Silicone and Parylene conformal coating via our trusted partners.
What is Conformal Coating and What is it Used For?
Conformal coating is a thin, protective layer which is applied to electronic components to shield them from environmental factors that could compromise their functionality.
Originally developed for military and aerospace applications, this technology is now a vital solution across industries – from automotive and medical to industrial and consumer electronics – where equipment is required to withstand tough conditions.
Conformal coating also offers several additional benefits:
- Moisture and Chemical Resistance: Protects electronics from moisture ingress and chemical contamination, extending their operational life.
- Vibration Dampening: Reduces the impact of vibration, minimising potential mechanical stress on sensitive components.
- Reduced Current Leakage: Provides a stable, insulated surface, helping prevent unwanted current leakage that could otherwise lead to malfunction.
Flexible Coating Solutions for Every Application
Active-PCB Solutions can provide a range of conformal coating techniques, allowing us to accommodate a broad range of product specifications and environmental requirements.
If we are not able to provide the optimum coating for your product via our in-house facility, then we are able to rely on our network of trusted partners.
- Spray Coating: A versatile, efficient option for even coverage that provides effective protection against contaminants and mechanical stress.
- Potting: Potting encloses components fully for maximum protection in extreme conditions, ideal for applications needing robust, long-term stability.
We understand that every project’s needs are unique, and our experienced team will consult with you to determine the optimal coating method, materials, and specifications to meet your performance, durability, and environmental requirements.
