Abstract
The global metal bonding adhesives market has to shift toward more environmentally friendly and preferably economically superior alternatives to traditional petroleum-based adhesives. Here, we report a two-component biobased adhesive system consisting of epoxidized biobased oils and biobased acids, with five biobased options available for each component category. Our strategy employs a method where two components are blended and melted to form a homogeneous mixture and, then, chemically cross-linked to form a covalent network upon heating. This approach has achieved high adhesive strength under dry and wet conditions for single-lap-joint bonded specimens. The materials tested include aluminum, copper, steel, brass, and molybdenum. Specifically, the lap shear strength of aluminum (1060) joints achieved a result of 6.2 ± 0.8 MPa under dry conditions and 4.4 ± 0.6 MPa under wet conditions.
This study presents a two-component biobased adhesive system for metal bonding, formulated from epoxidized soybean oil and organic acids. It offers high bonding strength, good water resistance, and a reduced carbon footprint.
