Silway 749 is a solventless silicone concentrate that is based on a mixture of silane and siloxane.
Dilute solutions of Silway 749 in organic solvents serve as high-quality general-purpose water repellents for impregnating and priming mineral and highly alkaline substrates.
Silway 749 is suitable for imparting water repellency to absorbent, porous, mineral construction materials and etc.

Features
• Good depth of penetration
• High resistance to alkalis
• Tack-free drying
• Effective even on damp substrates
• Rapid development of water repellency
After application to the mineral substrate,Silway 749 reacts with the atmospheric moisture or pore water in the substrate,thereby generating the active ingredient while liberating alcohol. The active ingredient greatly lowers the water absorbency of the substrate, which nevertheless retains a very high degree of water vapour permeability since neither pores nor capillaries are clogged.
Application
Silway 749 is suitable for imparting water repellency to absorbent, porous, mineral construction materials
Silway 749 is also suitable as primer for exterior paints.
