Epoxy resin AB glue is another name for two-liquid mixed hardening glue. One liquid is the glue, one liquid is hardener, and the two liquid phases are mixed to harden. It is not required to be hard to be cooked by temperature, so it is room temperature hardening glue. One kind, the model is sometimes used!
AB gums having components such as acrylic acid, epoxy, and polyurethane are commercially available. When used in the factory, it is abbreviated to the conventional large canned (1 kg / 2 kg set) epoxy resin. The toothpaste tube is simply referred to as AB glue (the bold name on the box).
Generally used is an acrylic modified epoxy or epoxy. The A component is an acrylic modified epoxy or epoxy resin, or contains a catalyst and other auxiliaries, the B component is a modified amine or other hardener, or contains a catalyst and other auxiliaries. Mix in a certain proportion. The catalyst can control the curing time, and other additives can control properties (such as viscosity, rigidity, flexibility, adhesion, etc.). The performance of the AB glue sold on the market has been determined on the formula. Generally, the change is not big. If there is a big change, it needs to be customized to the manufacturer.
The modified acrylic modified epoxy or epoxy adhesive has the characteristics of fast drying. After mixing AB, it will dry out at 5 degrees at 25 degrees, and the higher the temperature, the shorter the drying time. It can bond plastic and plastic, plastic and metal, metal and metal. After bonding, peeling requires tool or hot melt separation. The bonding effect between plastic and plastic is excellent, almost equivalent to the strength of ABS, and is widely used for hand-made improvement.
Epoxy AB glue is a two component epoxy glue. In addition to the high bonding strength, high hardness and high chemical resistance of the general epoxy resin, it also has an anti-yellowing effect. Even if it is painted on the vertical surface or ceiling, it will not sag, and it is dry and solid, safe and environmentally friendly.
Fast dispensing system with AB glue
AB glue has a high bond strength, but there are also some shortcomings, such as long curing time, poor mixing by hand, poor curing, long curing time and so on. At present, there is a quick dispensing system that can be solved. This system has been popularized abroad, and it has not been popularized in China. Most people use traditional methods for dispensing glue. This system is mainly composed of three large parts: glue gun, two-component syringe and mixing tube. The glue factory uses a two-component syringe to pre-package the AB glue in the AB glue syringe. When it is used, it is placed on the glue gun, and then the mixing tube is connected to the glue outlet, and the mixing page inside the mixing tube is used. The two kinds of glue mixing tubes are evenly distributed (usually after 7 knots, the use is mostly 17 knots, the mixing effect is quite several hundred times that of manual), and the glue is applied to the parts to be bonded.
