The durability and permanence of wood glue depends on many factors, including the type of glue, the environment in which it is used, and whether it is properly maintained. For example, white glue is a commonly used woodworking glue. It is made by synthesizing vinyl acetate from acetic acid and ethylene, and then polymerizing it into a milky white thick liquid through emulsion polymerization. White glue has the characteristics of curing at room temperature, fast curing, high bonding strength, good toughness and durability of the bonding layer, and is not easy to age. However, the durability of white glue is not unlimited. It is affected by environmental factors such as temperature and humidity, which may affect its bonding effect.
Additionally, the lifespan of wood glue is limited by its expiration date. Generally speaking, wood glue has an expiration date of 18-36 months. This means that even when used under optimal conditions, the adhesive strength of wood glue will weaken over time. Therefore, wood glue is not a permanent adhesive.
In summary, although wood glue can provide a stable bond for a considerable period of time under normal use conditions, it is not a permanent adhesive, and its durability and permanence are affected by many factors, including the type of glue, the environment in which it is used, and whether it is properly maintained.
