Silanes are chemical compounds based on silicon and hydrogen. Organosilanes, which are formed by partial substitution of hydrogen atoms by organic compounds, are used for surface functionalization.



In the construction industry, silanes are added to both cement and hydrated lime-based dry mortars, to reduce water absorption.

Silane can be also used as  adhesion promoter.
