This property has attracted huge interest in recent years due to its broad impact on industrial applications, including self-cleaning, corrosion resistance, anti-fouling, anti-icing, anti-graffiti, and water-oil separation.

Optimum performance at the lowest thickness / Ainhoa Altube in EUROPEAN COATINGS JOURNAL (ECJ), (01-02/2024)  

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > (01-02/2024) . - p. 28-31 Titre : Optimum performance at the lowest thickness : PSZN-containing coatings for enhanced protection at low curing temperatures Type de document : texte imprimé Auteurs : Ainhoa Altube, Auteur ; Ana Vinuales, Auteur ; Eva García-Lecina, Auteur ; Estibaliz Rodriguez, Auteur Année de publication : 2024 Article en page(s) : p. 28-31 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Anticorrosifs Anticorrosion Hydrophobie Métaux -- Revêtements protecteurs Polysilazanes Résistance thermique Revêtements organiques Silanes Sol-gel, Procédé Index. décimale : 667.9 Revêtements et enduits Résumé : When it comes to corrosion protection coatings, sol-gel based formulations have many advantages over conventional organic paints. However, to get the best performance from such formulations they must be cured at high temperatures (around 150 °C), which means that the process is energy-consuming and has a high environmental impact. However, lower curing temperatures, especially at room temperature, normally yield very porous non-protective coatings. Moreover, some large parts cannot be placed in an oven (e. g. a ship’s hull) and others are heat-sensitive substrates (polymers) that deteriorate when heated.
