PureBond® offers formaldehyde free plywood that also can be FSC certified. The adhesive is a soy-based glue that was developed based on the research of Dr. Kaichang Li, a professor at Oregon State University’s College of Forestry. Using biomimicry as a starting point he studied how mussels adhere to surfaces under such tough conditions. The isolated proteins were recreated using soy, being both strong and having a natural resistance to water. The adhesive’s benefits of being naturally occurring and non-polluting mean that the glues do not off-gas potentially hazardous formaldehyde.
