3. Nanotechnology (Ceramic)
Nanotechnology (or Ceramic) has significant hydrophobic glass coating delivery. It creates an invisible, durable coating that is water-repellent, residue resistant, and even has anti-static properties. Using proprietary nanotechnology, Nanotechnology windshield rain-repellent treatment coatings are long-lasting (1-2 years), and durable.

Aquapel Chemistry
The chemistry of Aquapel is not based on silicone polymers. It takes its technology from the aviation industry. The Aquapel Glass Treatment consists of fluorinated compounds called fluoroalkylsilanes. Fluoroalkylsilanes create a chemical bond with glass surfaces, causing water to bead up and roll off. This chemical bond with glass results in Aquapel lasting much longer than silicone-based rain repellents.
Aquapel has gained popularity in microfluidic-based biochemistry, specifically the Drop-Seq method pioneered by the McCarroll lab at Harvard.
