Abstract

Researchers at Purdue University have developed a high-strength, sustainably-sourced adhesive. Current commercially available high-strength adhesives are derived from petroleum feedstocks. These glues are often toxic and permanent, which prevents the reuse/recycling of the materials to which they are bonded. The Purdue adhesive is derived from soybean oil and is non-toxic and debondable. According to lap shear strength testing, the adhesive exceeded the strength of Super Glue and epoxy for metal substrates, polished aluminum and sandblasted aluminum. The adhesive also performed similarly to epoxy for a plastic substrate, PVC. The adhesive applied to aluminum substrates began to lose strength after submersion in water for a few hours, indicating that it is debondable and non-permanent. Among the adhesive’s many potential applications, it shows promise to replace rivets in automobiles and trucks, reducing weight and potentially increasing fuel efficiency by 0.1%. Technology Validation: Lap shear testing with the adhesive applied to polished aluminum, sandblasted aluminum, and PVC plastic was conducted. Advantages – Low-cost, readily-available starting materials – High-strength – Debondable – Non-toxic Applications – Adhesive for metal, plastics, and other materials
