LIQUIGLIDE VS. ALTERNATIVES
LiquiGlide’s slippery coatings are often confused with super-hydrophobic surfaces, but there are important differences.
SUPERHYDROPHOBIC
A conventional superhydrophobic surface is a highly textured surface that creates a cushion of air for the product to sit on, a phenomenon commonly referred to as the “lotus leaf effect.” Such surfaces rarely work with viscous liquids and are typically made with materials that are not safe for food applications. Further, over time, superhydrophobic surfaces break down and lose their slipperiness.
LiquiGlide creates durable, slippery surfaces using a proprietary thermodynamic algorithm to pair liquids with solid, textured surfaces that leverage chemical affinity and capillarity to stabilize the liquid. Over time, the surface continues to be slippery because the liquid is held in place between the textures. Because our surfaces can be made from a wide-range of combinations of materials, they can be designed to be edible or to withstand harsh industrial environments.
