Sodium Methyl Siliconate

Product Name: Sodium Methyl Siliconate

Item No: SilibaseWR-0777

Introduction:

SilibaseWR-0777 is a water-dilutable solution of Sodium Methyl Siliconate(Potassium siliconate) developed to impart water repellency to a wide variety of natural stone and masonry surfaces. The siliconate reacts with carbon dioxide in the air to form an insoluble repellent surface and reduce water absorption within 24 hours. It is suitable for the surface of natural stone, like sandstone, limestone, and red brick, gray brick, granite, ceramics etc.; it is not suitable for polished or glazed surfaces. 

Chemical Name: Potassium Methyl Siliconate

Feature:

Reduces water absorption into the substrate, thus reducing spalling due to freeze-thaw and efflorescence, thereby increasing the life of the substrate. 

Colorless and non-yellowing protection preserves the natural appearance of the substrate. Will not form a surface film or gloss. 

Treated surfaces retain natural vapor permeability. 

Suitable for interior and exterior surfaces. 

No solvent odor. 

Non-flammable. 

Typical Physical Properties:

CAS No.: 31795-24-1

Application:

SilibaseWR-0777 Sodium Methyl Siliconate is supplied concentration of 42 percent in water; SilibaseWR-0777 Sodium Methyl Siliconate is usually diluted to a concentration of 3 percent solids or less before application. To prepare a 3 percent solution, mix one-liter SilibaseWR-0777 Sodium Methyl Siliconate as supplied, with 13 liters of water.  

Application should be avoided on extremely windy days to avoid rapid evaporation of the water carrier.
