AB glue is the name of two-component glue. One liquid is an adhesive and the other is a hardener. Only when two liquids are mixed can they become hard. AB glue with acrylic acid, epoxy, polyurethane and other components is commercially available. When the toothpaste tube is used in the factory, the epoxy resin which is different from the conventional large tank (1 kg /2 kg set) is simply called AB glue (eye-catching name on the packaging box).
Usually used refers to acrylic modified epoxy glue or epoxy glue. A component is acrylic acid modified epoxy resin or epoxy resin, or contains catalyst and other additives, and B component is modified amine or other curing agent, or contains catalyst and other additives. Mix in a certain proportion. Catalyst can control curing time, and other additives can control properties (such as viscosity, rigidity, flexibility, adhesion, etc. ). The properties of AB glue sold in the market are determined in the formula and generally do not change much. If there is a big change, it needs to be customized for the manufacturer.

Modified acrylic acid modified epoxy or epoxy resin adhesive has the characteristics of quick drying. A\B After mixing, dry at 25 degrees for 5 minutes. The higher the temperature, the shorter the drying time. Plastic and plastic, plastic and metal, metal and metal can be bonded, and peeling after bonding requires cutting tools or hot melt separation. The bonding effect between plastics is excellent, almost equal to the strength of ABS, and it is widely used in manual improvement.
Epoxy resin AB adhesive is a two-component epoxy resin adhesive. It not only has the high bonding strength, high hardness and high chemical resistance of ordinary epoxy resin adhesive, but also has the effect of anti-yellowing. Even if it is scraped on the vertical plane or ceiling, it will not sag, and it is moderately dry, safe and environmentally friendly.
