Semblant’s MobileShield™ is Designed to Life-proof Mobile Devices

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.



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.

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 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.

Research shows that 1 in 4
smartphones dies or gets damaged every 2 seconds in the U.S. That equals…

173 Phones damaged by liquid ingress
347 Total phones broken

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.
