Adhesion promotion

Inorganic substrates, such as metals, ceramics, and glass are problematic as coatings often do not adhere well. Silanes can help as adhesion promoters. They are used in one of two ways.


The silane can be added directly into the coating formulation. Care has to be taken, so that the silane is compatible with the formulation.


Diluted silane solutions can be used for the formulation of adhesion promotion primers. Dynasylan® organofunctional silanes act as a bridge between the organic coating and the inorganic substrate and thus are excellent adhesion promoters. An application of the primer can be done using usual methods (spraying, dipping, roll coating).
