Product Description

Low Voc solventless waterborne hydrophobic emulsion based on silane and siloxane mixtures SiFS-3003C

SiFS-3003C is a solvent-less and water-soluble hydrophobic emulsion based on silane and siloxane mixtures. It is a high quality, general-purpose water repellents for impregnating and priming mineral surfaces. It can be also used in waterborne polymer primers like acrylic formulations to improve hydrophobicity.

Features
SiFS-3003C contains a stabilized mixture of silanes and siloxanes, which will occurs hydrolysis after application to the substrate, the emulsion is converted into a silicone resin. The silicone resin performs as a "hydrophobic film" which reduces the capillary absorption, but does not clog pores or capillaries, it also keep building materials "breathable".

• Good depth of penetration
• Resistance to alkalis
• Provides good adhesion for paints
• Low VOC, environmental-friendly
• Stable in storage, even diluted

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
