The reason why nail free glue cannot be applied thickly
Common methods of nail free glue:
1. Squeeze the nail free glue in a zigzag shape or spots at a distance of 20- 40cm.
2. Press the applied side against the bonding area, then pull it apart and let the glue evaporate for 5 minutes.
3. Press both sides tightly.
So why Squeeze the nail free glue in a zigzag rather than being applied thickly? The reason include affecting the appearance of the object, reducing viscosity, the possibility of drawing and falling during use and so on.
The effects of thick coating can be roughly divided into:
1. Curing problem: If the nail free glue is applied too thickly, the outer layer of the glue may cure, but the inner layer of the glue may not cure completely due to lack of contact with air. The nail free adhesive that cannot be cured is difficult to achieve the best bonding, so it is unable to bear heavy objects.
2. Reduced viscosity: The viscosity of the nail free glue may be reduced if it is applied too thickly, which will affect its bonding effect. This results in wire drawing and falling off during use.
3. Appearance impact: Full nail free glue is unsightly, so you need to pay special attention to details when using it and avoid applying it too thickly.
Therefore, when using nail free glue, you should avoid applying it too thickly, but only apply it on a few spots or zigzag shape to save material costs and maintain a good bonding effect. At the same time, you also need to pay attention to the use conditions of nail free glue, such as maintaining appropriate temperature and humidity, and avoiding the gel state of nail free glue.
