SiSiB® WR5055

SiSiB® WR5055 is a free-flowing, redispersible hydrophobic powder based on reactive silane/siloxane compounds encapsulated within a mineral carrier. Upon mixing with water, the silicone is rapidly released, chemically bonding to the cementitious matrix and forming a highly durable water-repellent barrier. 

SiSiB® WR5055
