Just as the lotus leaf sheds water and contaminants, so does our Shark Walk Purist, through low surface tension shielding the inside of your bottle from odor, staining, and mold build-up. With a simple rinse of the bottle, our Shark Walk Purist ensures that water from the bottle does not taste like plastic or the previous liquid.
Each Shark Walk Purist bottle is infused with silicon dioxide (SIO2) in a process known as Plasma Enhanced Chemical Vapor Deposition (PECVD). In this process, silicon dioxide is added to the polymer structure of the inner surface of the bottle, forming the protective glass-like barrier that prevents odors, stains, and mold from permanently attaching to the inside surface of the bottle.
This Purist infusion is added after the bottle has been molded and is chemically bonded to the bottle wall. The barrier is an extremely thin 20 nanometers—over 5,000 times thinner than a human hair.
By infusing the silicon dioxide, no compromise is made to the structure, and the bottle remains totally flexible for easier drinking. It will not delaminate or fall off, even when the bottle is flexed over and over.
