Researchers Develop Plant-Based Resin

A new resin made from soybean, corn and other plant oils could be used to formulate a wide range of coatings and adhesives, according to researchers.

Kansas State University scientists report that they have developed and patented “the first plant-based resin of its kind.” Recommended applications include re-adherable painters’ tape, labels, packing tapes, stationery notes and other adhesive uses.

Donghai Wang, professor of biological and agricultural engineering, and Susan Sun, university distinguished professor of grain science and industry, developed a patented biodegradable resin for adhesives and coatings.

"Painters generally finish projects with mounds of used tape made of low-quality paper that does not recycle," said Susan Sun, university distinguished professor of grain science and industry and lead researcher on the project. "If they could use biodegradable tape, like ours, it would greatly reduce the amount of waste."

The resin could also be used in coatings for wooden surfaces, slick magazine pages, bags of potato chips and other items needing shiny and protective surfaces that are either flexible or rigid.

Water-Resistant, Plant-Based Resin

Sun said the technology “outperforms previous bio-based adhesives because it adheres to a surface for a longer period of time.”

Further, she says the resin has a longer shelf life and is more water-resistant than other technologies. As the substance is plant-based, its resources are biodegradable and renewable, she adds.

“Currently available resins are made from petroleum-based products, which are less sustainable, and from plant fatty acids, which cost more to process,” Sun said.

Funding, Patent

Initial funding was provided by the Kansas Soybean Commission and the United Soybean Board. Additional funding sources include the U.S. Department of Agriculture and the National Institute of Food and Agriculture.

Sun developed the resin with Donghai Wang, professor of biological and agricultural engineering, and Kollbe Ahn, a 2011 Kansas State University grain science doctoral graduate who is now a research professor at the University of California, Santa Barbara.

The patent was issued to the Kansas State University Research Foundation, a nonprofit corporation responsible for managing technology transfer activities at the university.
