Nanotechnology & coatings glossary
Clear definitions of the surface-science terms behind WetProof coatings.
- Hydrophobic
- A hydrophobic surface repels water, causing droplets to bead up rather than spread, typically with a water contact angle above 90°.
- Superhydrophobic
- A superhydrophobic surface is extremely water-repellent, with a water contact angle above 150°, so droplets barely touch the surface and roll off almost instantly.
- Hydrophilic
- A hydrophilic surface attracts water, causing it to spread into a thin even sheet rather than bead, typically with a contact angle below 90°.
- Self-Healing
- A self-healing coating automatically repairs fine scratches and swirl marks, typically when triggered by heat, restoring the surface without polishing.
- Nanotechnology coating
- An ultra-thin protective layer engineered at the nanometer scale that changes how a surface interacts with water, light, chemicals and wear.
- Water contact angle
- The angle at which a water droplet meets a surface; below 90° is hydrophilic (water spreads), above 90° is hydrophobic and above 150° is superhydrophobic (water beads).
- Lotus effect
- A self-cleaning effect where water droplets roll off a superhydrophobic surface and carry dirt away, inspired by the lotus leaf.
- Ceramic coating
- A liquid polymer coating that bonds to a surface to add hydrophobic protection and gloss; WetProof’s Excalibur NanoFilm goes further with an impact-activated, much thicker layer.
