Outline Of Shoe Adhesive Operation Matters Needing Attention

1. before processing, the material, material and treatment agent should be fully recognized.

2. choose suitable glue according to different materials and combinations. Different series of agents should be treated with different series of treatment agents.

3., strive to be completely uniform, and replace gauze and cotton regularly to ensure the processing effect.

4. after the drying agent is fully dried, it is then glued and glued evenly to avoid accumulation of glue and thickness.

5. material with rough surface, suitable for high gluing and high viscosity agent at one time. If it needs two times, it needs drying for the first time and two times for glue.

6. when the agent is added to the hardening agent, the general ratio is 3-5%. As the proportion of the hardening agent is large, it is easy to sink to the bottom, so the right and left sides are fully stirred to ensure uniformity.

7. hardener is very easy to react with air moisture. After use, it should immediately tighten the mouth to avoid deterioration, and then affect the effect.

8. hardener is mainly composed of polyisocyanate and organic solvent. Polyisocyanate is easy to react with various substances. Therefore, it should avoid contacting with human body. If it is touched, it can be cleaned with plenty of water.

9. light coloured material, if you want the appearance, you can add light coloured hardener (such as AD652W, etc.) in addition to the light coloured agent.

10. then nylon or rubber material, hardening agent, please use DESMODUR RF (650BF or 651RF).

11. after drying, the drying temperature should be set at 55~65 degrees. The drying time should be 5~8 minutes. After gluing and gluing, it is avoided to blow or place in wet place, resulting in surface crust or surface mist.

12. choose the best time for sticking, one alignment, try to avoid rip up and fit again.

13. after fitting, it is necessary to complete all the pressurization actions in the sticky maintenance time. After too long, the pressure is not enough.

14. pressure time and pressure should be properly set. The greater the pressure, the better. But with the principle of shoe material not being deformed, time should be controlled for more than 5 seconds.

15. after use, the brush can be cleaned with suitable solvent. The brush can be washed with toluene and PU is cleaned by MEK.

16. when using finishing agent to remove vamp dirt, prevent solvent from infiltrating into the agent layer and destroy the crystallization, resulting in subsequent bad.

17. the following agents and hardener contain second kinds of organic solvents. The use should be heated directly away from the fire, just in case.
