BreckTech Potassium Methyl Siliconate
Breckenridge Technologies · BreckTech
BreckTech Potassium Methyl Siliconate is a water-dilutable solution of potassium methyl siliconate developed for water repellency on masonry and natural stone surfaces. It reacts with carbon dioxide in the air, forming an insoluble surface that reduces water absorption, providing long-term protection against spalling and efflorescence. It’s suitable for interior and exterior surfaces like surface of natural stone, like sandstone, limestone, and red brick, gray brick, granite, ceramics etc., retaining natural vapor permeability and not suitable for polished or glazed surfaces
- Yellowing resistance
- Low odor
- Good weathering properties
