Eva Book Binding Glue

The advantage of Eva Book Binding Glue is obvious, especially in its fluidity control. In the molten state, the gel can be accurately adjusted to the honey-like viscosity, and with the automatic sizing equipment, a uniform film layer of 0.1-0.3mm can be formed at the spine of the book, effectively avoiding the problem of "glue line cracking" common in traditional glue. For special materials such as lightweight paper and coated paper, the adhesive liquid can penetrate to the fiber pore depth of 30-50μm, and laboratory data show that its peel strength can reach 4.5N/cm², far exceeding the industry standard.

The third party test verified that the shear strength retention rate of the colloid exceeded 90% in the range of -20℃ to 60℃, and successfully passed the 72-hour high and low temperature cycle test. In practical application, the adhesive layer of the book spine remains intact after the sea temperature difference (-15℃ to 50℃) and 85%RH humidity environment.

It is worth noting that its bonding performance is suitable for a variety of industrial scenarios: in the gray board pasting process of hardcover book cases, the colloid is cooled to form a molecular-level bond with the PVC coated surface; When the wireless adhesive machine is running at high speed (2000 copies/hour), it can still maintain a stable opening time and curing rate. A number of publishing houses reported that the average service life of educational AIDS bound with this adhesive was increased by about 40% in frequent leafing tests.
