SiSiB® PC1210 is a bifunctional silane with reactive amino groups and hydrolyzable inorganic ethoxysilyl groups. Due to the nature of its amino group, this substance reacts as a strong base. The silane hydrolyzes autocatalytically in the presence of moisture (ethanol is released) to form silanols, which can then react with themselves to produce siloxanes or can bind to inorganic substrates. As a bifunctional organosilane, it can bind to both inorganic materials and organic polymers to function as a molecular bridge between organic and inorganic substrates.

SiSiB® PC1210 (equal to KBE603) is a clear, colorless, strongly alkaline liquid.
