Is AB glue resistant to high temperatures?

It is not very resistant to high temperatures. General AB glue can only withstand high temperatures of 90 degrees for a long time, but can withstand temperatures of 200 degrees in an instant. This is AB glue used for bonding, which is ordinary AB glue. Another type is the high-temperature resistant AB glue used in the industry. However, the bonding strength of this kind of AB glue is not high. It can withstand temperatures up to 800 degrees. If you use ordinary AB glue, be careful that the temperature does not exceed 200 degrees and it will not burn.

Extended information:

AB glue is another name for two-liquid mixed hardening glue. One liquid is the glue and the other is the hardener. The two liquids can be mixed to harden. It does not need to be It is hardened and matured by temperature, so it is a kind of normal temperature hardening glue, which is sometimes used when making models. Generally used in industry.

AB glue is the name of a two-component adhesive. AB glues with acrylic, epoxy, polyurethane and other ingredients are commercially available. When the factory uses epoxy resin to distinguish the toothpaste tubes from conventional large cans (1kg/2kg set), it is referred to as AB glue (the eye-catching name on the packaging box).

Component A is acrylic modified epoxy or epoxy resin, or contains catalysts and other additives, and component B is modified amine or other hardeners, or contains catalysts and other additives. Mix in a certain proportion. The catalyst can control the curing time, and other additives can control the properties (such as viscosity, rigidity, flexibility, adhesion, etc.). The performance of the AB glue sold on the market has been determined in terms of formula, and generally there will be little change. If there are major changes, you need to request customization from the manufacturer.

Modified acrylic modified epoxy or epoxy resin adhesive has quick-drying characteristics. After mixing A\B, it will dry in 5 minutes at 25 degrees. The higher the temperature, the shorter the drying time. It can bond plastic to plastic, plastic to metal, and metal to metal. Peeling off after bonding requires a knife or hot melt separation. The bonding effect between plastic and plastic is excellent, almost equal to the strength of ABS, and it is widely used to improve the production of figures.

Epoxy resin AB glue is a two-component epoxy resin glue. In addition to the high bonding strength, high hardness, and high chemical resistance that ordinary epoxy resin glue has, it also has an anti-yellowing effect. It does not sag even when applied on vertical surfaces or suspended ceilings, has moderate drying and is safe and environmentally friendly.
