SiFS-3003 is a silane & siloxane emulsion with excellent penetration, it will penetrate into the substrate and does not block capillary when applied on the surface of the substrate. A hydrophobic film is formed because of the reaction between reactive groups and -OH groups in the substrate to form a Si-R chain, fill the surface of capillary, and improve the strength of the substrate. The water contact angle can reach 120°. SiFS-3003 is an ideal choice for building materials and surface protection.
Properties
• Penetrating and breathable, penetration depth≥3 mm
• Colorless, preserve the natural appearance of the substrate

ABOUT SILICONE WATER REPELLENT
Silicone waterproofing agent: A series of chemicals/mixtures which containing Si-O bonds and alkyl groups (like methyl, octyl group) in the molecular structure.
The machanism of silicone water repellent:
The SiOH (silicon hydroxy) group react with the substrate to form a thin resin film:
• The silane reacts with water (Hydrolysis reaction) to form SiOH (silicon hydroxy) group and it is can be bond to the OH (hydroxy) of the substrate.
• The silanes occurs condensation reaction to form a Si-O-Si group. The alkyl group (R group) of surface is effectively hydrophobic.
• Most of the molecules of siloxanes and silanes are small with strong permeability. It is has a breathable waterproof effect after curing , and than
prevents liquid water that may contain dissolved chloride or acid from penetrating into the substrate
