Silicon dioxide, also known as silica, is commonly used in printing coatings due to its excellent properties. Here are some reasons why silicon dioxide is used for printing coating: 1. Abrasion resistance: Silicon dioxide has a high hardness, making it resistant to wear and abrasion. This property helps protect the printed material from scratches, ensuring its durability. 2. Scratch resistance: The hardness of silicon dioxide also provides scratch resistance to the printed surface. This is especially important for materials that are frequently handled or subjected to friction. 3. Anti-blocking properties: Silicon dioxide particles in the coating formulation can help prevent blocking, which is the sticking together of printed surfaces when stacked or rolled. This property ensures that the printed materials can be easily separated without damage. 4. Gloss enhancement: Silicon dioxide can enhance the gloss of printed materials…
