Casein, a protein derived from milk, has a history that stretches back thousands of years, proving its enduring utility and adaptability. From its early use by the ancient Egyptians as a binder in paints and adhesives to its widespread adoption in woodworking, furniture making, and even the construction of early aircraft, casein has consistently demonstrated its value as a reliable and versatile material. Its journey highlights the ingenuity of past generations in harnessing natural resources for practical applications.

The core of casein's effectiveness lies in its properties as a binder. When casein powder is combined with alkaline substances like lime or borax, and sometimes water or glycerin, it forms a potent adhesive. This makes it an excellent choice for woodworking, providing a strong and durable bond that has stood the test of time. Many historical musical instruments and pieces of furniture owe their longevity to the strength of casein glue. The ability to simply mix casein powder with water and an alkali to create a functional glue is a testament to its accessibility and ease of use, making it a favored option for both historical reenactors and modern DIY enthusiasts.

Beyond adhesives, casein is renowned for its role in the art world. As a binder for pigments, it creates casein paints, known for their matte finish and vibrant, lightfast colors. Artists appreciate casein paints for their quick drying time and the unique textural qualities they offer, making them suitable for various artistic techniques. The versatility of casein powder extends to its use in food products, where it contributes to texture and acts as a nutritional supplement due to its high protein content. In the pharmaceutical industry, it also serves as an excipient in drug formulations. The continuous demand for casein underscores its importance as a natural, sustainable, and multifaceted ingredient in today's diverse industrial landscape. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. continue to supply high-quality casein to meet these varied needs.
