Dow Corning OFS-6341 (N-octyltriethoxysilane) is a hydrophobic silane coupling agent that enhances adhesion and waterproofing in coatings and composites. Its small molecular structure enables deep penetration into concrete and metals, forming durable siloxane crosslinks for >90% wet adhesion retention. Ideal for infrastructure protection, it complies with REACH/RoHS and reduces VOC emissions (329 g/L). Applications include concrete waterproofing, metal anti-corrosion, and polyolefin filler modification
