WEST LAFAYETTE, Ind. – Patent-pending adhesive formulations developed at Purdue University from fully sustainable, bio-based components establish bonds that grow stronger when underwater or exposed to wet conditions.

Gudrun Schmidt, an associate professor of practice in Purdue’s Department of Chemistry, and a team of researchers developed the formulations from zein, a protein found in corn, and tannic acid. A paper about the team’s research was published in the peer-reviewed journal ACS Applied Materials & Interfaces.
