REPEL WB40 water based alkylalkoxysilane with a 40% active ingredient.
Repel has been formulated to penetrate dense concrete, reacting within the pores to form a long lasting water repellent lining thus protecting the embedded reinforcement from the corrosive action of water and chlorides.
■ Excellent penetration for in-depth protection and durability
■ One coat application
■ Water-based for ease of application and safety
■ Can be applied to damp surfaces
■ Will not change the surface appearance.
■ No wastage, opened containers can be re-sealed and re- used.
■ Quick, easy and economic to use.
■ Ready to use for maximum quality control.
■ Non flammable
■ Non hazardous
Essentially silane is a monomer, ie a single molecule therefore small in size allowing penetration into dense substrates. Other products in the same chemical group, siloxane and silicones are combinations of molecules and therefore larger in size with less penetrating ability. All products in this group once re-acted within the substrate form a silicone, known for their excellent water repellent qualities.
