What Is Casein Glue?
Casein glue is a natural adhesive made from casein, a protein found in milk.
This glue has long been used in woodworking, papermaking, and food packaging, with its use expanding due to its safety and environmental friendliness. It is made of casein, an alkali, and formaldehyde. In alkaline solutions, casein dissolves and hardens upon drying to form a strong adhesive. Formaldehyde helps by forming cross-links between casein molecules, enhancing the hardening process.
Casein glue is utilized across several applications including woodworking, papermaking, and food packaging. It is appreciated for its natural origin, safety, biodegradability, and low environmental impact. Its strong adhesive properties and ease of use in aqueous solutions make it a preferred choice in many industries.
