Market Opportunity

The global market for hydrophobic coatings is expected to increase from $1.3 billion in 2015 to more than $1.8 billion in 2020, growing at a five-year compound annual growth rate (CAGR) of 6.4% from 2015 through 2020. The current state-of-the-art super hydrophobic surface layer is very thin and can be easily abraded or damaged. Moreover, the skin layer of the prepared bulk material is not super hydrophobic and should be removed to expose the inner super hydrophobic material. Therefore, NUS technology has proven to be comparatively superior to the current state-of-the art.


This invention describes a method using polymers and silicon oxide nanoparticles to prepare a super hydrophobic coating. This method of coating has been tested on rigid polymer/plastic and rubber and may also be used on metals.
