High-Strength, Nontoxic Adhesives from Plant Components

People are surrounded by and exposed to toxic glues in their daily environment. Such glues keep car parts together, houses and furniture in place, and books and cardboard boxes together. Almost none of these adhesives are approved for medical applications inside the human body. Given the toxicity of such adhesives, there is a need for nontoxic adhesives with bonding strengths as high as structural adhesives such as Super Glue*.

Researchers at Purdue University have developed a nontoxic adhesive composition derived from a readily available plant protein and phenolics. This technology is substantially free of formaldehyde and has an adhesion strength that is roughly comparable to commercial Super Glue*. This high performance, nontoxic adhesive uses biobased components that are readily available, resulting in a low-cost adhesive.
