SILRES BS 16 (IMPREGNATING SILICONE)

SILRES BS 16 is an aqueous solution based on potassium methyl siliconate, used in diluted form to impart water-repellent properties to mineral building materials. It reacts with atmospheric carbon dioxide (CO2) to form polymethylsilicic acid, thereby developing excellent hydrophobic (water-repellent) properties on the applied surfaces.

Areas of Application

• Low-temperature fired clay products immediately after production (roof tiles, facing bricks, floor tiles, flower pots)
• Autoclaved aerated concrete and autoclaved aerated concrete granules
• Gypsum and gypsum-based fiberboards
• Lightweight fillers such as perlite and vermiculite
• Insulation materials

Application and Processing Details

SILRES BS 16 is supplied as a concentrate and must be diluted with normal tap water before use. It is recommended to add the product to water under vigorous stirring. It should be applied by methods that ensure homogeneous coating, such as dipping. Important Note: Its use on exterior walls is not recommended, as irregular application may lead to the formation of white stains. Furthermore, double-layer application is not advised.

Technical Specifications

Storage and Packaging

Must be stored in its tightly sealed original packaging. Should be stored in stainless steel, plastic, or glass containers. Tin, aluminum, galvanized, or lacquered containers are not suitable. If crystallization occurs at low temperatures, the product will redissolve upon heating (must be thoroughly stirred before use).
