SiSiB® WR0812

Silane Water Repellent

SiSiB® WR0812 is clear colorless liquid with a characteristic odor.


SiSiB® WR0812 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® WR0812 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.


SiSiB® WR0812 is equal to Dow's Z-6672, Wacker's SILANE IO-TRIETHOXY.
