Family of silicone-hydrogene-compounds with the chemical formula SinH2n+2 or SinH2n (circular  "Cyclo"silanes). They are frequently used for coating surfaces for further treatment, most particularly for coating yarns and fabrics. Silanes usually bond perfectly to mineralic, metallic and oxide surfaces. They usually provide good bonding for printings and lamination.

Textile coatings
Textile yarns are often treated by silanes.
