potassium methyl siliconate

SiSiB® WR0778 is a water-dilutable solution of potassium 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.


SiSiB® WR0778 is suitable for the silicone construction surface of natural stone, like sandstone, limestone, and red brick, gray brick, granite, ceramics etc.; it is not suitable for polished or glazed surfaces. It is similar to Wacker's Silres BS16, Dow's OFS-0777.
