Product overview
n-Octyltriethoxysilane is a long-chain alkyl silane used to impart hydrophobicity to porous mineral substrates. It is evaluated in concrete and masonry protection systems where deep penetration and reduced water uptake are required.
Function & Usage
- Promote Adhesion & Silane Coupling
Promotes adhesion or interfacial coupling between selected substrates, fillers, resins or polymer systems. Typical uses: Concrete water repellency, Masonry treatment, Mineral surface hydrophobization.
- Repel Water & Hydrophobize Surfaces
Reduces water uptake or increases surface hydrophobicity in suitable mineral, masonry, concrete or coating systems. Typical uses: Concrete water repellency, Masonry treatment, Mineral surface hydrophobization.
- Improve Mortar Workability & Set Control
Supports workability, water management, set profile, adhesion or durability in cementitious and dry-mix systems. Typical uses: Concrete water repellency, Masonry treatment, Mineral surface hydrophobization.
