Low molecular alkylalkoxy siloxane
Funcosil SNL Silane Impregnation is a low odour hydrophobic, microcidal agent that is used as a deep penetrating, water repelling impregnation for all types of absorbent facade building materials. Funcosil SNL can be distinguished by its high alkali resistance. The substrate surface to be impregnated can show pH values of up to 14 without adversely affecting the properties of the impregnation. After application the active agent is deposited as a layer on the capillary and pore walls. This does not influence the water vapour diffusion capacity.
All types of absorbent masonry facade building materials.
