Soy-Based Formaldehyde Free Wood Glue Unveiled
Rising Petrol Prices Increase Interest in Formaldehyde Free Wood Glue
This week at the 240th National Meeting of the American Chemical Association, representatives from the USDA Forest Products Laboratory unveiled a new type of wood glue that is environmentally friendly and formaldehyde free. A key component of this new wood glue, soy flour, is actually derived from common foods like tofu and soy milk.
Interest in an environmentally friendly, formaldehyde free wood glue has increased in recent years, although soy-based glues still make up less than five percent of all wood glues. According to Charles Frihart, one of the researchers working on this project, a combination of factors has pushed glue producers toward making an environmentally friendly, formaldehyde free glue. These factors include rising petrol prices, an increased interest in sustainable and environmentally friendly forms of production, and the harmful side effects that can be caused by traditional wood glues, which are not formaldehyde free. Formaldehyde is a possible carcinogen that also causes short-term side effects, including skin irritation and burning in the eyes, nose, and throat.
Formaldehyde free soy-based wood glue has become a more viable product in recent years due to recent advancements in technology. The new soy-based wood glue fared well in initial tests, and Frihart and the other researchers will now be focusing on refining this environmentally friendly wood glue to make it even more effective.
