The adhesive industry is developing rapidly, and water-based adhesives can occupy a place under fierce competition, which is inseparable from the excellent characteristics of water-based adhesives. These characteristics are mainly reflected in the following 5 points:
(1) Excellent product hygiene performance
Water-based adhesive itself is non-toxic, it does not have the problem of solvent residue like solvent-based adhesive, nor does it have the problem of PAA residue in solvent-free adhesive , and there is no peculiar smell after drying, so it has high food safety performance.
(2) Efficient production efficiency
The operating conditions of high solid content and the requirement of low gluing amount, as well as the incompatibility of water and acrylic acid make the moisture to be dried easily dried , so its production efficiency can be increased by more than 20% compared with solvent glue. The high molecular weight adhesive design greatly shortens the curing time and makes it possible to ship quickly.
(3) Good affinity for aluminum plating
The characteristics of acrylic resin determine the good composite strength between the adhesive and the aluminum plating layer, the high degree of molecular prepolymerization of the water-based adhesive and the design of flexible molecular chains , to further avoid the problem of unqualified composite strength caused by the transfer of the aluminum plating layer.
(4) Improve working environment and reduce pollution
Because the water-based adhesive does not need to be diluted, it can be directly produced on the machine, which reduces the labor of the operator to prepare the adhesive, and also avoids the solvent in the air at the work site. Concentration, which is quite beneficial to the operators, and at the same time avoids the discharge of solvents, and has no pollution to the environment. Of course, without the presence of solvent, the hidden danger of fire is avoided.
(5) Effectively reduce the occurrence of quality accidents
Compound products with water-based glue, you can see the quality of the product very intuitively, as long as you carefully check the appearance and composite strength of the product when it is offline, There will be no adverse changes over time, especially the composite strength and appearance. After a period of time, with the blending of the adhesive molecules, the composite strength will increase and the appearance will become better.
