Characterising superhydrophobic epoxy coatings embedded by new nanomaterials

Superhydrophobic surfaces attracted great attention to protect different substrates from water, dust and corrosive environment.

In a work, new calcium carbonate nanomaterials modified with epoxidised fatty acid are used to alter the hydrophilic characteristics of epoxy resins.

Optimum CaCO3 content was 5 wt%

The best conditions to coat the glass and steel surface with hydrophobic calcium carbonate were investigated to obtain superhydrophobic surfaces. The surface morphologies, thermal stability, crystal structure, particle sizes and shapes were also reported and discussed. Results showed that the epoxy coatings embedded by optimum CaCO3 content was 5 wt% to produce superhydrophobic epoxy with high water contact and low slide angles.

The study is published in: Progress in Organic Coatings, Volume 101, December 2016, Pages 577–586

EC Library Epoxy Resins


Epoxy Resins

Thanks to their excellent characteristics, epoxy resins belong to the most established binders within the coatings industry. This new book explains the basic principles of the chemistry of the epoxy group and imparts the use of epoxy and phenoxy resins in industrial coatings, such as anticorrosive coatings, floor coatings, powder coatings and can coatings, with the help of concrete formulations. Essential for any formulator of competitive modern paint systems!
