Perhydra is a scalable surface treatment to impart extreme hydrophilic properties to metal, alloy, polymer, composite, and ceramic substrates. The treatment improves the spreading and wettability of water-based solutions, while reducing frictional drag.

The Perhydra process transforms the surface of the substrate through a proprietary treatment process engineered by Oceanit. Treated surfaces subsequently become highly attractive to water based fluids, allowing for near-total wetting. Perhydra reduces the occurrence of corrosion, increases abrasion resistance and is designed for use in conditions where extreme temperature and pressure exist.

The coating can be used to vastly improve the adhesion between substances like concrete and steel or mill varnished steel. For example, in casing pipes, cement-steel interface/adhesion can be improved by integrating Perhydra surface treatment.

The surface treatment process is highly scalable with applications for substrates and components on length scales ranging from less than an inch to hundreds of feet and longer. Sample applications for Perhydra include: improving water-spreading in evaporative coolers, ensuring uniform coverage and adhesion of water-based paints and solutions on surfaces, and reducing mechanical friction through enhanced lubricant adhesion.

Oceanit has also developed a super hydrophobic treatment, Anhyrda which you can read more about here.
