Silicone Waterproof Agent Potassium Methyl Siliconate for Densifier for Concrete

SiFS-16 is an aqueous solution of potassium methyl siliconate designed for the impregnation of mineral construction materials. When diluted, it serves as a powerful waterproofing agent. It reacts with atmospheric carbon dioxide (CO2) to form an active water-resistant substance that firmly bonds with the masonry surface within 24 hours.

• Ideal and economical water repellent for various construction materials.
• Highly effective for porous substrates.
• Preserves the natural appearance of the substrate.
• Reacts with atmospheric CO2 to form a durable barrier.

■Imparts water repellency to:

• Porous building materials like bricks and roof tiles.
• Aerated concrete and concrete densifiers.
• Gypsum and gypsum-based fiber boards.
• Light fillers such as perlite and vermiculites.
• Mortars and aqueous construction coatings.

How to Use: For surface treatment, dilute SiFS-16 with water 21-25 times before use. Methods such as dipping or spraying are necessary to achieve a uniform coating. Note: Not recommended for colored exterior walls as uneven application may cause white spots.

The SiOH (silicon hydroxy) group reacts with the substrate to form a thin, breathable resin film:

• Hydrolysis: Silane reacts with water to form SiOH groups that bond to the substrate.
• Condensation: Forms a Si-O-Si network where the alkyl group creates a hydrophobic surface.
• Permeability: Small molecules ensure strong penetration while maintaining breathability.
