Brief Project Summary:
Health hazards associated with the use of formaldehyde-based adhesives in wood products have led to an interest in developing water-based adhesives from renewable resources. Soy protein has been studied for green wood adhesive formulation. However, they contain synthetic components and cannot cure at ambient temperatures for adequate bonding strength. The lack of characteristics, such as mildew resistance and flame retardancy, also limits its application in the wood products industry. Researchers intend to develop a fully bio-based, ambient temperature-curable, soy protein adhesive with excellent pre-pressing bonding strength, flame retardancy, and mildew resistance. Prototype foamed wood siding and particle board will be made and tested to demonstrate the new adhesive.

Project Summary

Health and environmental hazards associated with the extensive use of formaldehyde-based
adhesives in wood products (e.g., particle board, fiberboard, wood panel, oriented strand boards,
plywood, and laminates) industry have led to an increasing interest in developing competent waterbased
adhesives from renewable biomass resources. Among the various types of biomass, soy
protein has been widely studied for the formulation of green wood adhesives because of its low
cost and ability to bond with different materials. However, most current soy protein-based
adhesives still contain synthetic components and cannot cure at ambient temperature to provide
adequate pre-pressing bonding strength. Challenges remain to produce a fully bio-based soy
protein adhesive system that cures at ambient temperature and possesses excellent pre-pressing
adhesion for a larger market share. In addition, the lack of other perspective characteristics such
as mildew resistance and flame retardancy also limits their large-scale and multipurpose
applications in the wood products industry. Therefore, in this project, our goal is to develop a fully
bio-based and ambient temperature-curable soy protein adhesive with excellent pre-pressing
bonding strength, flame retardancy, and mildew resistance. Prototype foamed wood siding and
particle board will be made and tested to demonstrate the industrial uses of the new adhesive.

Project Objectives

Develop flame-retardant, mildew-resistant soy adhesive with high pre-pressing strength and
strong wet adhesion and use it for foamed wood siding and particle board production.

Project Deliverables

• Formulation and method for producing soy adhesives with flame and mildew-resistant,
ambient-curing, and wet adhesion properties
• Formulation and method for producing foamed wood siding and particle board using the
adhesive

• Increased soybean value and additional income source for soybean farmers

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
