Product Description

General purpose water repellents for hydrophobic impregnating and priming mineral surfaces

SiFS-4004 is a water-based, solvent-less emulsion based on a mixture of silane and siloxane. Served as general purpose water repellents for hydrophobic impregnating and priming mineral surfaces, SiFS-4004 is characterized by an excellent beading effect, especially applied as mass hydrophobation for non-load bearing concrete to prolong the life span of building materials.

Feature
• Water-based and environmental compatible, Non-toxic
• Good depth of penetration
• Highly durable and effective beading effect
• Stable in storage, even when diluted
• Keep building materials "breathable"

Application
Dilute SiFS-4004 is an excellent water repellent for many porous mineral substrates, such as bricks, sand-lime brick,natural sandstone, mineral plasters and other silicate building materials. Owing to its aqueous consistency and storage stability when diluted, SiFS-4004 is ideal for mass hydrophobation of building materials made of clay, aerated concrete, sand-lime brick, mineral fiber,etc.
 

How to Use
• Additive for concrete:Recommended dosage of SiFS-4004 is 1.0 % to 3.0 % by weight of the cement.
• Surface treatment use:Recommended active substance content of 5-10% (dilute the product in the ratio 1:5 to 1:8), the exact figure depending on how absorbent the substrate is. Homogenize the concentrate before use.


Package
• 25L, 200L Plastic Drum or 1000L IBC tote.
 

 

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
