Silane coating is a metal surface pre-treatment introduced as a replacement for chromium treatments. It is supposed to be suited for various metals, including aluminium, steel and galvanised steel. Good corrosion performance has been assigned to these hybrid organic–inorganic thin film deposition systems.
Why is silane coating?
Silane has the ability to react on both the organic and inorganic sides, a feature that offers numerous possibilities to model coating materials to suit required profiles. The silanes are used for corrosion protection, adhesion promotion and other surface modification applications.
What is an example of silane?
An example is silane tetrahydride an inorganic compound with chemical formula, SiH4, making it a group 14 hydride. It is a colourless, pyrophoric, toxic gas with a sharp, repulsive smell, somewhat similar to that of acetic acid. Silane is of practical interest as a precursor to elemental silicon.
