LiquiGlide Nonstick Coating

LiquiGlide nonstick coating prevents waste in packaging

Never leave any ketchup behind with LiquiGlide nonstick coating

Have you ever gotten to that last bit of sauce, glue, or shampoo in a bottle and wished there were a way to use every last drop? Well, it turns out this happens to MIT professors too. While investigating liquid-impregnated, slippery surfaces to solve a problem found in oil and gas pipelines, the team at MIT realized that what they had created could have many more applications, including manufacturing and packaging. LiquiGlide nonstick coating was born.

LiquiGlide’s coatings are custom designed to be hyper slippery and permanently wet, using materials that are safe for each specific application. It isn’t just ketchup bottles that benefit from LiquiGlide’s nonstick properties. The coating also has applications in oil and gas, agrochemical, medical, and industrial markets.

What is LiquiGlide nonstick coating made of?

The difference between LiquiGlide and other superhydrophobic surfaces is not just chemical, but also physical. Superhydrophobic coatings work by providing a highly textured surface at the nanoscopic scale, which liquids and other substances cannot fully adhere to; a cushion of air forms between the substance and the surface, which is why they come off without leaving a trace. The problem is that the highly textured surface will break down over time or with abrasion, so the coating loses its superhydrophobicity.

The breakthrough that makes LiquiGlide permanently slippery is impregnating a textured coating with liquid. The customized solid surface contains the impregnating liquid, and so creates a slippery, liquid surface – like it is permanently wet. LiquiGlide is the first and only company to create permanently wet slippery surfaces. The coating is also self-healing, scratches or abrasions will naturally fill and cover.

LiquiGlide nonstick coating: applications and benefits

The world of consumer packaging alone can be revolutionized by LiquiGlide. Think of all the waste saved if every detergent, sauce, lotion, oil, paint, and glue container was coated in LiquiGlide. As much as 15% of every one of these products is simply thrown away. But the applications beyond packaging are also extensive:

  • Manufacturing: Eliminate waste from containers and equipment adhesion, reduce cleaning and increase production through reducing down-time. Increase batch yield.
  • Agrochemical: Accurately measure dosages, reduce waste with complete evacuation of insecticides, pesticides, and herbicides. LiquiGlide is also patent-protected and difficult to reproduce, so it can reduce counterfeiting.
  • Oil and gas: Increase flowability and reduce resistance in pipelines and wells, prevent build-up in pipelines, reduce waste in packaging.
  • Medical: Prevent clogging and blockages in tubes, allow precise dosages with no waste, improve lubrication for endoscopes.
  • Future: Preventing ice build up on power lines and plane wings. Increasing efficiency of condensers in power plants. Increasing efficiency in water treatment.

Industrial waste solution with LiquiGlide CleanTanX

“Viscous products sticking to the inside of tanks leads to huge ineffiencies across industries,” said LiquiGlide’s Co-founder and Chairman of the Board, and MIT Professor, Kripa Varanasi. “For example, in paint manufacturing alone, paint sticking to the inside of mixing and holding tanks costs the industry more than 100 million gallons of lost product and billions of dollars per year in associated waste costs. At LiquiGlide, we are on a mission to eliminate waste generated in the manufacturing of viscous products and usher in a new era of sustainable manufacturing.”

With the LiquiGlide CleanTanX system, the company is combating the manufacturing challenges created by viscous liquids sticking to equipment, such as blenders, reactors and tanks. The CleanTanX system has been shown to reduce product waste, wash water, and associated cleaning costs in manufacturing tank applications by up to 95%. The technology can be applied at manufacture or retrofitted onsite without having to remove the tanks, thus minimizing installation costs and operational downtime.
