SiSiB® PC5912 is clear colorless liquid with a characteristic odor. It is the equivalent of Wacker's SILRES BS1701.
SiSiB® PC5912 silane crosslinking agent is suitable for water-repellent impregnation of construction materials (especially concrete and reinforced concrete). It increases their resistance to alkalis and reduces water absorption, thus improving durability. SiSiB® PC5912 is practically insoluble in water. It hydrolyze slowly in the presence of moisture (ethanol is released) to form reactive silanols, which can react with themselves to produce siloxanes.

Like SiSiB® PC 5901 n octyltrimethoxysilane, SiSiB® PC5912 can also be used as a surface modifier to generate hydrophobicity and to increase compatibility to organic non polar matrices.
SiSiB® PC5912 can be used in the production of silane crosslinking formulations.
SiSiB® PC5912 alkyl alkoxy silane can be used to render a wide range of surfaces and materials water repellent (e.g.construction materials, fillers), especially concrete and reinforced concrete.
SiSiB® PC5912 is supplied in 175Kg steel drum.
In the unopened original container SiSiB® PC5912 has a shelf life of one year in a dry and cool place.
