Waterproofing Agent
CAS Number: 68440-70-0
A silane/siloxane-based waterproofing agent that imparts deep water repellency to mineral substrates including concrete, masonry, and natural stone. It chemically bonds with the substrate at the molecular level to create a durable hydrophobic barrier without altering surface appearance or vapor permeability. Provides long-lasting protection against water ingress, chloride ion penetration, and freeze-thaw damage.
