Hybrid coating system enables sustainable multi-cure applications

These hybrid coatings combine the durability of inorganic materials with the versatility of organic polymers. A key innovation lies in the formulation’s ability to independently and efficiently cure under different conditions, or in combination, offering plural-cure capabilities. This is enabled by a tailored blend of reactive alkoxysilanes and blocked catalysts.

Using FTIR spectroscopy, the team tracked the curing process and assessed the conversion of alkoxysilane groups. Comparative analyses revealed that curing method significantly affects final film properties, providing valuable insight for targeted applications.

With their high solids content, reduced VOC emissions and adaptable curing, these OIH systems represent a promising step towards more sustainable and high-performance coatings—particularly for complex industrial and automotive applications where flexibility in processing is essential.
