This droplet penetration test shows that water-repellent silicone fluid emulsions from WACKER reliably protect mineral wool from moisture. Thanks to its low viscosity, the new SILRES^® BS 5137 can be processed very efficiently.

Modern EIFS for building insulation consist of a multi-layered material composite. But only the addition of a dispersible polymer powder creates a firm bond to the insulating material and thus a permanently stable insulation system.
