is a global provider of coating technology for electronic devices and printed circuit boards.
As one of the original creators and innovators in conformal coatings, HumiSeal® pioneered and has continued to innovate this protective technology for over 60 years. We encourage customers to partner with us in developing products that are tailored to their exact requirements.
Humiseal offers different Electronic Protection Conformal Coatings - shown below. Navigating the selection of appropriate coating materials and application processes can pose challenges and consume significant time, especially for those unfamiliar with the subject. Partner with Humiseal to get the best advice or a tailored solution!


The Problem: Uneven Conformal Coating Coverage
Conformal coating distribution often ends up too thin around corners and too thick in areas prone to accumulation. This imbalance can be just as damaging as under-coverage, leading to potential failures such as:
- Electro-migration on the coating surface
- System failures from condensation on the PCA
- Unrestricted growth of tin whiskers
These issues highlight the need for a solution that ensures precise and consistent coverage across all areas of the PCB.
Our Solution: HumiSeal SEC Technology
To tackle these challenges, HumiSeal developed the Sharp Edge Coverage (SEC) product line, featuring 1B59SEC and 1A33SEC. These advanced coatings:
- Adhere tightly around component sides for single-layer PCB protection
- Offer faster and stronger protection with UV-curing capabilities
Our commitment to innovation in conformal coating technology is detailed in our white paper, Conformal Coatings - New Solutions to Existing Problems. Ready to explore these cutting-edge solutions? Fill out the form to get started today!
