Momentive WETLINK78 is an epoxy-functional silane coupling agent optimized for waterborne adhesives and sealants. It enhances wet adhesion, mechanical strength, and storage stability in one-component systems through covalent bonding between organic polymers and inorganic substrates. Ideal for automotive, furniture, and construction applications, it offers non-yellowing performance, rapid curing at ambient temperatures, and compliance with environmental regulations
Dual Reactivity - Epoxy group bonds with resins; ethoxy links to fillers/metals
Wet Adhesion Boost - Maintains 90%+ bond strength after water immersion
Process Efficiency - Reduces viscosity (0.978 g/cm³) for easier formulation
Long Shelf Life - 12+ months stability in single-component systems
