Product Description
Silicone Water Repellent for Gypsum Plaster Board Hydrogen Silicone Oil SiFS-94
SiFS-94 is a trimethylsiloxy terminated polymethylhydrogensiloxane. The molecule has a relatively active Si-H bond, it can react with reactive groups such as a double bond and hydroxyl group by catalyst, and the self-crosslinking reaction can also occur. As an additive to gypsum, it can be added to the interior of gypsum to achieve a good waterproof effect, and reducing the water absorption of gypsum. SiFS-94 can also be used as a raw material for the production of other modified silicone oils and other special applications.

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.
APPLICATIONS OF SILICONE WATER REPELLENT
The machanism of silicone water repellent:
The SiOH (silicon hydroxy) group react with the substrate to form a thin resin film:
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
