Traditional Waterproofing vs. Conformal Coating Waterproofing

Traditional Waterproofing vs. Conformal Coating Waterproofing

These days, we take our electronic devices everywhere and expect them to be waterproof. People want to take photos at the beach and in the swimming pool, some tweets and texts must be delivered while in the shower, and bath time isn’t the same without a movie on your shiny new iPad.

We get it.

The problem is that water is in more places than you realize. Liquid can creep into devices in more ways than we can see, and what you may consider a “safe place” to rest your device may not be safe. Lately, companies all over the world are trying to stop this problem. Everywhere you turn, a new phone, camera, or tablet is announced with the added benefit of “waterproof” protection.

Traditional Device Waterproofing

For a phone, headphones, tablet, or wearable to be deemed waterproof, it has to be completely sealed against water. Most companies add this protection by either “ruggedizing” the product, which generally makes it pretty big and bulky, or by adding seals to the inside that act as a barrier against liquid ingress. Physical barriers sound like a great idea until you consider that these seals are easily damaged or dislodged.

When the product is dropped, when the temperature around the product becomes too hot or cold, or when the seal is not placed properly, the seal can allow water and moisture inside the product. Even a tiny amount of liquid can cause long-term problems with corrosion and short-circuiting that won’t be noticed until it’s too late. Say goodbye to all the pictures you took last Christmas and shots of your favorite cat, Sprinkles. They are gone for good.

Waterproofing with Conformal Coatings

Now that you know these “waterproof” products are only as waterproof as the rubber seals inside, this is where we come in. If you haven’t figured it out by now, we here at HZO offer the world an alternative to internal rubber seals and bulky, ugly cases. We don’t protect against water leaking into your device. We protect against water in your device. HZO coatings create a barrier between your product and any liquid that could potentially cause harm to a completely waterproof electronic.
