Precautions for storage and storage of water-based sealing glue
1. Storage and transportation should be at 0°C-50°C, and avoid sunlight exposure. The molecular structure of glue below 0°C is easy to change, which will weaken or even fail the glue.
2. It is recommended to use it first to avoid expiration. The shelf life is 6-9 months under normal conditions.
3. The remaining glue must be sealed and stored
4. Disposal and disposal should be in accordance with relevant local laws and regulations
Precautions for the use of water-based sealing glue
1. Be sure to choose a suitable model before use
2. Tests must be carried out before formal production, and then mass production after confirmation
3. Pay attention to the material condition before use, such as: surface energy, base layer thickness, varnish thickness, film corona value, etc. If the material is particularly poor, take remedial measures, such as edging, plasma damage, etc.
4. Glue is active. Its activity varies with temperature. The best activity is at 15 °C. Therefore, when using glue in winter, it is best to place the glue in an environment of 15 °C one day in advance, so that the effect will be better when used. Some
5. Before putting on the machine, be sure to stir well. The glue will generate water vapor under the current temperature conditions, and the water vapor will condense on the lid of the barrel. The water droplets formed by the water vapor after logistics transportation will fall into the glue. When the new glue is used, there will be a crust or water film on the surface of the glue, so be sure to mix it well
6. During use, the captain should check the amount of glue in the glue tank and the amount of glue applied to the product at any time to avoid no glue or uneven glue on the product.
7. For more than 60 minutes of shutdown, it is best to pour the glue out of the glue tank, wash and dry the glue tank (it is recommended to dry it with compressed air to avoid residual water); if the actual operation is difficult, it is recommended to use the glue tank with Wrap it in plastic wrap to prevent the glue from contacting the air for a long time, forming glue crust and affecting the next production
8. The glued box should have sufficient extrusion time, it is recommended to exceed 20 minutes, in order to use the two bonding surfaces to fully contact the glue particles, and the extrusion time of film-coated products should be extended.
9. There should be sufficient resting time until the moisture in the glue has completely evaporated, the glue particles are in contact, and the extrusion time of the film-coated product should be extended.
10. This product cannot be mixed with other similar products or solvents
11. After 24 hours, be sure to check whether the product is firmly bonded
