Conformal Coating - ABchimie PCBA Protection

ABchimie's Conformal Coatings

ABchimie’s conformal coatings range provide high level environmental protection for PCBAs.

By applying a thin layer, typically 25 to 50 microns thick, these coatings can significantly improve a PCBA’s working life, reliability, and performance. They protect the PCBA from harsh conditions like salt spray, humidity, extreme temperatures, solvents, and dust, which can otherwise cause corrosion, current leakage, and premature failure. Our full product line offers a variety of base materials, including:

Acrylic varnish

UV-curable urethane acrylic

Silicone varnish (resin)

Varnish Dual cure UV

Urethane varnish

Silicone varnish (Elastomere)

Why Choose ABchimie Conformal Coatings?

Health, Safety & Environmental Responsibility

ABchimie places a strong emphasis on health, safety, and sustainability. We are constantly innovating to offer “green” alternatives that reduce environmental impact without compromising performance.

One such product is AVR80 BA, a non-toxic, eco-friendly acrylic conformal coating formulated with a safer solvent system designed to protect both users and the environment. It has become a trusted solution across the automotive, military, and industrial sectors. In line with the shift toward next-generation coating technologies, we also offer ABchimie526 UV and ABchimie746 E UV. These advanced formulations are VOC-free and compatible with both UV mercury and 395nm LED curing systems, offering high-performance protection with reduced environmental impact.

We are dedicated to providing high-quality, ready-to-use conformal coatings tailored to meet the specific needs of your equipment and application processes. Custom viscosities are available on request, and our expert technical support team is here to guide you every step of the way. Delivering precise, reliable solutions is a core part of our commitment to earning and maintaining your trust.

APPLICATIONS METHODS

1. Spraying

A commonly used method that gives excellent results, especially on flat surfaces. Ideal for general applications requiring uniform coverage.

Aerosol spraying: perfectly suited for repairs and small to medium production runs.
Gun spraying: very economical for large production runs.

2. Selective coating in dispensing equipment (automated dispensing)

For high-volume, precision applications, automated dispensing systems such as those offered by companies like ASYMTEK, PVA, REHM, and AXXON MYCRONIC provide fast and reliable results. All ABchimie coatings can be used with the appropriate dispensing head, ensuring performance and efficiency on mass production lines for electronic boards.

3. Dip coating or dipping varnish

An efficient method for small production runs, dip coating ensures complete varnish coverage, including hard-to-reach areas under components.

CHOOSING A CONFORMAL COATING

To select an appropriate conformal coating, it’s essential to first identify your specific requirements:

- Which industry standards or regulations need to be complied with?
- What is the operating environment of your PCBA?
- Do you require a reworkable coating?
- What are your electrical performance requirements?
- Which application method will you use (spraying, dipping, selective coating, etc.)?

Our application engineers will assist you in identifying the most suitable solution for your specific requirements.
