Casein glue consists mainly of calcium hydroxide, sodium salt, and casein. It is particularly suitable for gluing wood but also has good adhesion to paper and all paper products in general, cork, and natural fabrics. It is often used as an adhesive for gluing labels to bottles because it adheres easily to glass and dissolves easily when washed.
Animal glue is created from by-products of the food industries such as skin and bones. It is only soluble in water, so once fully dried it forms a real barrier to waxes, fats, and oils. It is a very versatile, durable, and easy-to-use glue. Animal glue is mainly applied to paper and cardboard, natural fabrics, cork, and wood.
The basic substance of fish glue is fish skin, mainly from cod. An important characteristic is its resistance to high temperatures. It is used in the food industry as a thickener but is also used in other areas: as a strong fixative for hair or for gluing paper, paper products, cork, leather, and wood.
Natural glues are based on starch and its derivatives mostly extracted from seeds, tubers of wheat, maize, palm, potato, and tapioca. They have a high adhesive power on cellulose and are therefore particularly used for paper, cardboard, and wallpaper. They are also used to glue labels onto cans and glass bottles.
These are the most widely used natural glues. They can replace chemical glues, which are both polluting the environment and dangerous to human health. Why not give them a try?
