Product Description

Description

Silway 7288 is a solventless siliconeconcentrate that is based on amixture of silane and siloxane.

Dilute solutions of Silway 7288 in organic solvents and Dilute solutions of Silway 7288 serve as high-quality general-purpose water repellents forimpregnating and priming mineral and highly alkaline substrates.

Silway 7288 is suitable for imparting water repellency to absorbent, porous, mineral construction materials and etc.

Key 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 7288 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.
