Nanocoatings proven to protect electronic devices from liquid and corrosion damage

At Semblant, we’re on a mission to protect your digital lifestyle. We do this by innovating advanced nano-materials that protect our most rigorously used electronic devices from water and corrosion damage, making them impervious to the forces of nature encountered every day. Our special chemical solutions save the industry billions of dollars in return and repair costs, and save consumers a lot of pain, as well as a lot of money. Today, our deployed worldwide capacity exceeds one million mobile devices per day, and it continues to grow.



Unique materials, invented and engineered by Semblant, designed to protect today’s electronic devices from water, sweat, dust, dirt and human nature.

Cost Savings-small

Cost Savings

Every week, millions of consumer mobile devices fail. Semblant’s fully reworkable nano-coatings protect against environmental damage and allow for repairs such as swapping damaged components, preventing the need for device replacement.



Semblant’s unique nano-coatings are designed to be completely green, protecting both the environment and you. We are the only company to specifically engineer PFOA- and PFOS-free solutions.



Semblant has a deployed manufacturing capacity of over 1 million units coated per day and is able to deliver a quick-to-ramp, high-volume manufacturing approach.

Award Winning Technology

How It Works

Quick, repeatable, easy to adopt.

Semblant’s advanced nanotechnology is applied through a simple and easily scalable process that allows electronics to resist the elements and harsh environments. Together with our equipment partner Nordson MARCH, we have developed a proven, high-volume and environmentally-friendly system to apply our water- and corrosion-proof electronic device coatings.

The system is very easy to operate. Its one-stage, dry process requires no preparation or pre-mixing of materials. Just load and go.

Shielded by Semblant

Electronic devices are increasingly subject to teardown reports by industry experts and analysts who want to see exactly what is going on under the hood of today’s latest consumer products. Semblant’s protective nanocoating gives off a unique ‘psychedelic’ effect under illumination, meaning you can be sure Semblant is protecting that device from water, corrosion and other damage.

Better for the environment.
Better for you.

It’s not enough to offer the industry’s best protective nano-coatings. We have always been passionately committed to delivering waterproofing solutions that exceed the highest environmental and health standards. While many “water resistant” materials rely on chemistries such as long-chain fluoropolymers that contain PFOA- and PFOS,* we, along with companies like Nike, Apple, Patagonia and Gore, have eliminated these harmful chemicals from our products.
