Weiwang hot melt adhesive manufacturer tells you whether the hot melt adhesive is waterproof

Recently, a customer reported that he bought a children's hot-melt glue gun for children to make handicrafts. The children don't stick glue when they use it. He asked us what happened. After communication, it turned out that the child accidentally touched the kettle during use, and the water spilled down, resulting in unstable glue. We told the customer carefully that the hot-melt glue is not waterproof, When using, be careful not to have water nearby.

Weiwang hot melt adhesive products penetrate the surface of articles to achieve the bonding effect, but sometimes changes will occur after bonding the material, which will affect the bonding effect of hot melt adhesive at this time. During the production process, the high-temperature hot melt adhesive has effectively damaged the surface of materials, and its active glue molecules will enter the materials from the damaged surface. When the product is stained with water, Water molecules will enter the interior of the material, expanding the space between glue molecules and material molecules, so that the solidified hot-melt adhesive block loses its original adhesion auxiliary force and then looses out.

Therefore, the hot-melt adhesive is not stable in the water environment. The hot-melt adhesive products on the market are basically not waterproof, but it does not mean that they will be scrapped in case of water. Non waterproof refers to that the adhesive will be damaged if they encounter water for a long time in a certain structure. Hot melt adhesive itself has such natural defects. Now when we have a certain understanding of the use methods of hot melt adhesive, we can better apply it to our daily life. When we explained in detail to the customer, he also learned this knowledge. Weiwang hot melt adhesive bar manufacturer has a stable delivery time of hot melt adhesive, which is worthy of your trust.
