Hot Melt Adhesive For Book

Books and periodicals wireless binding Hot Melt Adhesive color is milky white, transparent, light yellow, white translucent, deep yellow. Hot Melt adhesives for books and periodicals are divided into edge adhesives and back adhesives according to their use. Edge glue: Sticky cover, generally need to be softer than the back glue, color requirements are not high. High viscosity requirement. Back glue: The color requirements are slightly higher. And hardness requirements greater. According to the shape: cylindrical particles, round particles, block these three kinds are mostly. Generally speaking, the more yellow the binding hot melt adhesive, the stronger its viscosity.

Hot melt adhesive curing speed, easy to use, low spraying temperature, impact resistance, fatigue resistance, good flatness, durable, strong adhesive force, compared with traditional adhesives, in the Book Binding Adhesive is more environmentally friendly and practical.

For post-press binding, the strength of hot melt adhesive book binding glue can reach the strength of ordinary other hot melt adhesive binding after 6 hours, and the strongest bonding effect can be achieved after 48 hours. The difference of surface properties of coated paper, ink, gloss oil, UV curing layer and plastic film has little effect on the binding properties of hot melt adhesive. Functional tests (such as page pulling and page turning tests) of the finished product will improve by more than 60% compared to conventional adhesives.

The hot melt adhesive binding layer is soft, and it is very convenient to turn books. As a crosslinked compound, it has excellent properties in shock vibration resistance and fatigue resistance. For some books that need flatness after long-term use, such as reference books, manuals, textbooks, recipes, etc., hot glue binding is undoubtedly the best choice. Due to the chemical crosslinking reaction of hot melt adhesive, it has excellent adhesion properties such as high heat resistance, low temperature resistance, solvent resistance and water resistance, and hot melt adhesive binding can fully meet the requirements of long-term preservation of books, such as photo albums, picture yearbooks, high-grade cultural relics calligraphy and painting books, and Bibles.
