Protectosil® 200N is an ultrapure, colorless, solvent-free liquid water repellent based on Isobutylalkoxysilane, intended for the external waterproofing of mineral building materials. The ultrapure material is quaranteed to not leave a residue on non-porcus substrates, such as glass or aluminum window framing. Protectosil® 200N chemically bonds with silaceous materials to form a permanent attachment of the water repellent molecule. Creates a deep hydrophobic layer which prevents water and waterborne contaminants from entering the substrate and causing premature detioration. Protectosil® 200N may be used as a concentrate or it can be diluted to manufacture other products and formulations.
