Protectosil® 166

Protectosil® 166 is a colorless, solvent-free liquid based on an reactive, oligomeric alkyl siloxane. The diluted solution of Protectosil® 166 is intended for the water-repellent impregnation of absorbent mineral facade construction materials.

Scope of Application

Areas of application: For waterproofing absorbent mineral facade construction materials such as: plaster facades sand-lime brickwork brickwork autoclaved aerated concrete cement fiber board Application rate: We recommend using a 10% solution of the active ingredient in an aliphatic hydrocarbon solvent (such as e.g. Shellsol D 40). The amount to be applied depends to a large extent on how absorbent the substrate is. Empirical values are, for example, approx. 0.5 - 1.0 l/m2 for mineral plaster facades, approx. 0.4 - 0.7 l/m2 for sand-lime brickwork, approx. 0.4 - 2.0 l/m2 for brickwork, approx. 0.5 - 2.0 l/m2 for autoclaved aerated concrete and approx. 0.1 - 0.3 l/m2 for cement fiber board. The exact amount to be applied must be determined by a trial application. Product Characteristics: water-vapor-permeable, colorless impregnation not film-forming effective on hairline cracks up to 0.3 mm good reduction of the water absorption good penetration high alkali resistance suitable as a primer for facade topcoats frost resistant
