Can hot melt glue prevent leakage from leaking?

2022-07-13

It is not friendly between the hot melt adhesive and water. In many applications of hot melt adhesive, water will cause it to lose its original bonding ability, but this is not absolute. It is necessary to prevent leakage. Plastic waterproof effect.

Water has excellent liquidity and can reach the degree of pervasion. In this case, the hot -melt glue must prevent the flow of water, and all pores and gaps must be shielded. The hot melt adhesive in our impression seems to be difficult to achieve this. Is there a way to solve it? —— Although the applicable conditions are harsh, there are still ways to complete this difficult task of leakage.

In the past, the experience told us that the hot melt glue was not sticky after encountering water. Have you ever wondered why you can't stick it? In other words, there are many types of glue for adhesive materials. Among the many glue, the scope of the scope of hot melt adhesive is relatively wide. But it is a huge flaw that is so recognized by the market, which is afraid of water. Even ordinary glue has a certain water resistance ability. How can hot -melt glue be so vulnerable to the water? The reason is that the molecular structure of the hot melt glue is too good! Temperature is self -evident on the effect of hot melt adhesive. The change of temperature can regulate the performance of the hot melt adhesive itself. It can be seen that the shielding ability of hot melt adhesive on its own performance is weak, and it has changed completely by the external influence. Water can easily invade on the surface of the hot melt adhesive. After dissolving with water, the hot -melt glue body will mutate, and the performance will also be affected and change.

However, if the hot melt adhesive encounters water, it will be different from the fusion of the material, and the result is very different. The principle of PUR reactive hot melt adhesive is in the principle of such destructive fusion, which can make the molecular and irregular staggered molecules of hot melt adhesive and materials, which will directly destroy the original molecular structure of the hot melt adhesive, greatly reduced or even even reduce or even reduce or even reduce it. Cutting off the impact of external factors on it, making the state of hot melt adhesive adhere to unprecedented stability. Under such conditions, the PUR reactive hot melt adhesive can block all the pores and gaps of the dwelling, let the water lose the flow, and play a role in preventing water leakage.

In addition, if the material is not allowed to fuse with the hot melt adhesive, and the characteristics of strong plasticity of the hot melt adhesive are used, although it cannot be sticky, as long as the pure hot melt adhesive can definitely solidify, use this feature to block this characteristic to block this characteristic to block this characteristic to block this characteristic to block this characteristic blocking. The place of water out of the water also has hope to achieve the effect of preventing water leakage, but it is necessary to practice more in actual operation.
