Epoxy resin adhesive is a kind of thermosetting polymer adhesive which is formed by the reaction of various epoxy resin and the curing agent. It has excellent bonding performance, high tensile strength, good acid and alkali resistance, excellent electrical insulation properties and chemical stability, and is widely used in packaging, paper products and other industries. Epoxy resin adhesives have some advantages, such as tear resistance, wide range of temperature and pressure resistance. They have high tensile strength, which can ensure that the entire package and paper products remain intact.
Epoxy resin adhesive is a kind of chemical adhesive, so its products should pay attention to safety, no matter it is used in production or in the process of use, simply because once the chemical reaction is out of control, it will cause damage or even hurt people. Therefore, users should pay attention to the safety and environmental protection when using it, and professionals should be required to operate it. In addition, due to the characteristics of epoxy resin, the drying time should be considered. Generally, it takes tens of minutes to days for epoxy resin adhesive to dry and solidify completely under the stimulation of strong air or ultraviolet radiation. This high drying time not only affects the efficiency of the production, but also wastes the glue resources.
In addition, the epoxy resin adhesive market is also very broad. Different curing systems are adopted according to different curing requirements. Like some epoxy resin adhesives, they can be divided into single-component type and two-component type in function. The single-component type relies on atmospheric moisture to solidify itself, and usually contains ammonium salt as a liquid curing agent; while the two-component type needs to be mixed before use, and there are no curing agents to provide additional time.
As a type of adhesive, the proper use of it will show its excellent performance in the bonding materials. For example, epoxy resin adhesive can not be used for materials such as rubber, fabrics, adhesives, adhesives and other invalid materials. In addition, when using epoxy resin adhesive, one should pay attention to the acid and alkali resistance of the adhesive. If the product is acid resistant, it should not be applied to alkaline materials; if it is alkaline resistant, it should not be applied to acidic materials.
Epoxy resin adhesive has been widely used due to its excellent performance. It is used for the bonding and packaging of products of enterprises and the packing of goods of consumers. It makes the products not only firmly bonded and protected, but also shows its excellent appearance, which is an important part of our daily life.
