1. Before processing, first fully identify the material, different materials, use different treatments
2. According to different materials and subsequent combinations, choose the right glue, different series of adhesives also need different series of treatment agent, special material of the treatment agent please follow the supplier's instructions to use correctly
3. The treatment should be thorough and uniform, and gauze and cotton should be changed frequently to ensure the treatment effect.
4. After the treatment agent is fully dried, it should be glued again, and the glue should be uniform so as to avoid glue accumulation and thickness or lack of glue.
5. The rough surface of the material, a glue suitable for the use of high-solid components, high viscosity adhesives, such as the second time last time, the first drying before the second glue
6. When the hardener is added to the hardener, the proportion is usually 3-5%. Since the hardener has a large specific gravity, it can easily sink to the bottom. Therefore, stir it to the right and left to ensure uniform
7. The hardening agent reacts easily with the water in the air. Immediately after use, the mouth should be tightly closed to prevent deterioration and affect the subsequent effect.
8. The main ingredient of hardener is polyisocyanate and organic solvent. Polyisocyanate is easy to produce chemical reaction with various substances. Therefore, it should avoid contact with human body. If you touch it, you can wash it with plenty of water.
9. Light-colored material, if you want to require appearance, in addition to light-color adhesive, light-colored hardener can be added (such as AD652W, etc.)
10. Nylon or rubber, hardener, please use DESMODUR RF (650BF or 651RF)
11. After gluing, the drying temperature should be set between 55~65 degrees, and the drying time should be 5~8 minutes. After the gluing and gluing, avoid blowing or placing it in a damp place, resulting in surface crusts. Or surface mist, resulting in bad
12. Select the best timing for sticking, one-time alignment, try to avoid tearing and reattachment
13. After bonding, be sure to complete the entire pressurizing operation within the sticky maintenance time. Pressurize it too much for too long.
14. The pressure time and pressure should be properly set. The greater the pressure, the better, but the principle is not to deform the shoes, and the time should be controlled more than 5 seconds.
15. After using the brush can be cleaned with a suitable solvent (the brush of the syrup can be cleaned with toluene, PU glue washed with MEK)
16. When using a finishing agent to remove dirt from the upper, prevent the solvent from penetrating into the adhesive layer, destroying the crystals, and causing defects
17. Adhesives and hardeners contain a second organic solvent and should be used directly away from fire to prevent heat. After use cover, save in a cool dry place
