It's no secret that conformal coatings increase the lifetime of electronic devices by providing a thin barrier that strengthens their ability to withstand harsh environmental conditions. That said, a lesser-known truth is adhesives and encapsulants provide a significantly higher level of protection on the entire assembly.

Why is that? Well, adhesives and encapsulants promote assembly protection by:

• creating environmental seals that protect against moisture and corrosion
• providing high-temperature resistance
• increasing shock and vibration-dampening
• generating strong bonds to a variety of substrates
• maintaining low shrinkage
• offering thermal conductivity

 HumiSeal UV20Gel is a unique, strong, and flexible gel coating developed to protect PCB (Printed Circuit Boards) components against environmental conditions and vibrations. UV20Gel has proven successful in many demanding industries and product families including-

Durable Protection for Demanding Automotive Requirements

HumiSeal chemists have been designing state-of-the-art conformal coatings for nearly 70 years, first producing UV curable coatings more than two decades ago. At that time, UV curable technology was considered the next generation of coatings, mainly due to its advantages; including:

UV20GEL is a recent innovation from the polymer scientists at HumiSeal.

It provides additional durability and ruggedization for printed circuit boards in demanding applications including automotive, aerospace, and appliances among others. This flexible, high adhesion gel is used for staking taller or sensitive components to provide resistance to vibration and mechanical shock conditions. 

Adoption of plug in -electric vehicles (EVs) has been slower than many expected, but there is little question the next few years will see adoption accelerate. Your hypersensitive dog will have to find new visitors to harass when your delivery drivers arrive without notice, driving to your door silently in all-electric commercial vans. Many of your favorite suppliers and stores have already ordered these vehicles. Game-changing battery and charging developments are eliminating range anxiety, and autonomous driving controls and safety innovations are in the final stages of building our trust.

A critical function of conformal coatings is to protect PCBs and electronics from damage caused by moisture and humidity. In this discussion, we will attempt to answer some of the more common questions we often hear regarding the level of protection you can expect from a conformal coating.

Are conformal coatings waterproof?

The above is probably the most common question and most misunderstood subject in the area of PCB protection

Electronics continue to be placed into harsher environments, and PCB component vibration dampening remains a challenge for many industries. When the solder connection strength is not going to be sufficient to withstand years of vibration, there is a solution: staking materials.

Numerous fields of industry manufacture products that are prone to high-vibration environments. Some of them are:
