Water repellent silane system
Protectosil 800 - Description
Protectosil 800 is a free-flowing, colorless, solvent-free liquid based on a monomeric alkylalkoxysilane. It is specifically intended for the water-repellent impregnation of mineral construction materials in outdoor areas.
Protectosil 800 is supplied ready to use. It is low volatility and viscosity make Protectosil 800 an easy-to-handle additive. During the hydrolysis reaction between water and Protectosil 800 a certain amount of ethanol (VOC) is released. Protectosil 800 is soluble in common non-polar organic solvents (e.g. petroleum ether, toluene).
