The adhesive industry is developing rapidly, and water-based adhesives can occupy a place in the fierce competition, which is inseparable from the excellent characteristics of water-based adhesives. These characteristics are mainly reflected in the following five 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 adhesives, nor does it have the problem of PAA residue in solvent-free adhesives. , and has 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 glue amount, as well as the incompatibility between water and acrylic acid, cause the moisture that needs to be dried to be easily dried. , so its production efficiency can be increased by more than 20% compared to solvent glue. The high molecular weight adhesive design greatly shortens the curing time and makes rapid shipment possible.
(3)Good affinity for aluminum plating
The characteristics of acrylic resin determine the good composite strength between the adhesive and the aluminized layer, the high molecular prepolymerization degree of the water-based adhesive and the flexible molecular chain design , to further avoid the problem of unqualified composite strength caused by transfer of the aluminum plating layer.
(4) Improve the working environment and reduce pollution
Because the water-based adhesive does not need to be diluted and can be produced directly on the machine, it reduces the labor of operators in preparing the adhesive and also avoids the release of solvents in the air at the work site. concentration, which is quite beneficial to operators, while also avoiding the emission of solvents and causing no pollution to the environment. Of course, without the presence of solvents, the risk of fire is avoided.
(5) Effectively reduce the occurrence of quality accidents
With water-based glue composite products, you can intuitively see the quality of the product. As long as you carefully check the appearance and composite strength of the product when it comes off the production line, it will be good. There will be no adverse changes over time, especially the composite strength and appearance. After being left for a period of time, as the adhesive molecules blend, the composite strength will increase and the appearance will become better.
