Abstract

Waterborne polyurethane (WBPU) sol-gel adhesives were prepared through a prepolymer process followed by a sol-gel reaction of (3-aminopropyl) triethoxysilane (APTES). The terminal amine group of APTES reacted with the NCO group of the prepolymer, and the ethoxy group created Si-O-Si branching by hydrolysis and condensation reactions in water at the dispersion step. Water swelling (%), tensile strength and Young's modulus of the synthesized WBPU sol-gel adhesives were improved by increasing APTES content. Synthesized WBPU sol-gel adhesives were used for bonding nylon fabrics. A significant improvement in adhesive strength was recorded, and the potential for good adhesive strength under water at moderately high temperature (up to 75 C) was observed with 6.84 mol% APTES in WBPU sol-gel adhesives.
