Wood glues
Glue is used when the adhesive is a solution of animal, vegetable or synthetic raw materials in water.
White glue (low-formaldehyde dispersion glue), which is suitable for all wood-to-wood bonding, is very well known. It can be thinned with water, but is no longer water-soluble after hardening. An exception to this is Titebond Classic wood glue, which is an aliphatic dispersion resin adhesive and can be dissolved again by water vapour and heat, even after the curing time.
Wood glues have a long curing time, which can last from several hours to a whole day. However, they are very resilient.

Natural glues are obtained from organic materials and have a long history in wood processing and other craft activities. Glues such as bone glue, hide glue (e.g. Titebond hide glue) and fish glue are made from animal waste products, whereas casein glue is made from milk proteins. As natural wood glues are made from renewable resources and are biodegradable, their production and disposal is less harmful to the environment. However, they generally have lower strength and resistance to water and chemicals than synthetic wood glues.
Synthetic glues are produced from petrochemical raw materials using chemical processes. They are usually easier to use than natural glues and offer greater versatility and higher performance, but are less environmentally friendly.
Application
- Wood joints: Ideal for permanent wood joints
- Large area bonding: Ideal for applications where large surfaces or long edges need to be bonded.
- Example from the turnery: segmented shells.
