No. Viscosity is just one of the many parameters of hot melt adhesive. Blindly pursuing high viscosity can lead to problems such as overflow, penetration, and difficulty in cleaning. Choosing particles depends on “matching”, not on a single number.
| Scene | Viscosity orientation | reason |
|---|---|---|
| Book and magazine adhesive packaging | Medium to high viscosity | Penetrating paper fibers, preventing falling pages |
| High speed sealing box | Medium viscosity and fast solidification | Balancing speed and initial adhesion |
| tissue paper | Low viscosity | Anti penetration glue damage literal |
Q: Does high viscosity make it stick firmly?
Answer: Not necessarily, excessive high viscosity can cause glue overflow and make it difficult to apply evenly.
Q: How do I know what viscosity to use?
Answer: Ask the manufacturer by paper type/box type/model, Sunlife hot melt adhesive provides parameter combinations.
Q: Can viscosity be adjusted on site?
Answer: It mainly depends on the model selection, and the temperature is only fine tuned for fluidity.
I’m not sure about the selection, Guangzhou Sunlife Trading will match the viscosity scheme of Sunlife hot melt adhesive according to your production line.
Quick printing of graphics and text:Hot melt adhesive granulesWhich is better than glue? Short version fast printing stores often struggle between hot melt adhesive particles (glue packaging) and white glue/latex water (lock thread or brush glue) when making joint albums and conference manuals. We compare from three aspects: speed, fastness, and appearance. Hot melt adhesive […]
Direct answer: Glue overflow dirtying the book pages is essentially due to at least one of the four variables, “glue amount, temperature, pressure, and rhythm,” exceeding the appropriate range. The three most common reasons are excessive glue application, high glue temperature leading to low viscosity, and excessive clamping pressure squeezing glue from the spine to […]
Conclusion first: Try not to mix the same batch number across seasons as much as possible Hot melt adhesive granulesThe performance fluctuates significantly with temperature. High temperature and humidity in summer, low temperature and dryness in winter, using the same adhesive can easily lead to “summer rebound and winter cracking”. It is recommended to switch […]
Conclusion first: Exported books and periodicals need to be transported across the ocean, through high-temperature containers and temperature differences between high and low temperatures. Ordinary rubber particles are prone to sticking or becoming brittle during transportation, while weather resistant hot melt rubber particles have a higher softening point and a more balanced resistance to high […]
