casein glue
Quick Summary
Casein glue is a water-resistant adhesive made from casein, which is the primary protein found in milk. It is typically combined with hydrated lime and mixed with cold water for use in applications like plywood and furniture making. Casein itself is a white, odorless solid that is a key component of cheese and is present in cow's milk at about 3%.12
This natural adhesive has a history of use, dating back to ancient Egypt for furniture construction. While synthetic adhesives are now common, casein glue remains valuable in woodworking and other industrial processes where its binding properties are beneficial.3
