Product Description

Solventless Silicone resin based long life span Mansory Water Repellent  Sifs-290

SiFS-290 is a solvent-free silane and siloxane concentration blends. It is dilutable with organic solvent. It can penetrate inside the building substrate to form an efficient and lasting water-proofing layer protection. Diluted solutions of SiFS-290 in organic solvent serves as a high-efficient, general-purpose water repellents for impregnating and priming mineral and alkaline substrates.

Features
• Good penetration with depth 3-10mm
• Extremely effective with most natural stone
• good alkali resistance

SiFS-290 reacts with the atmospheric moisture or pore water in the substrate, thereby generating the active
ingredient while releasing alcohol. It can penetrate inside the building substrate to form an efficient and lasting water-proofing layer protection, which nevertheless retains a very high degree of water vapour permeability since neither pores nor capillaries are clogged.

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
