WSE Defense: Development of Epoxy-based Wood Adhesives

Thin wood-based composites, such as plywood and particleboard, are bonded with a thermoset adhesive and are produced via a hot press process.  At present, UF is the most common thermoset adhesive used for production of wood-based composites.  The emission of the carcinogenic formaldehyde from UF-bonded panels during the use of panels affects the indoor air quality and causes many health problems.  In the first part of the research, two formaldehyde-free wood adhesives were developed by crosslinking the structures of soybean flour (SF) with poly (glycidyl methacrylate-co-styrene) (PGS) emulsions.

Thick wood-based composites, such as cross-laminated timber (CLT), glulam, and thick plywood, are bonded with a cold-set adhesive and are produced via a cold press process.  Resorcinol-formaldehyde (RF), phenol-resorcinol-formaldehyde (PRF), melamine-urea-formaldehyde (MUF), and polyurethanes (PUR) are the currently available cold-set wood adhesives.  They are all carcinogenic formaldehyde-based or very toxic isocyanates-based adhesives and are very hazardous during the production of wood-based composites.  In the second part of the research, two formaldehyde-free and isocyanates-free cold-set wood adhesives were developed based on epoxy-resins that do not have any major hazardous issue.

Yahya is completing a PhD program double majoring in Wood Science and Materials Science. He has a B.Sc. and M.Sc. in Polymer Engineering from Tehran, Iran. He is currently exploring various job opportunities.
