AB adhesive is a type of structural adhesive produced by adhesive manufacturers
It is necessary to mix the two components before adhesive force can be generated. Generally, complete curing takes 24 hours, and the strength after curing is very high. After curing, it has a certain degree of waterproofing, but it is best to avoid contact with water before curing, as this may have a certain impact on the bonding effect.
For items that have already been bonded with AB glue, soaking them in water for a long time may cause the glue to peel off. There are various types of AB structural adhesive, among which epoxy adhesive has better resistance, DM epoxy adhesive can achieve waterproof effect, while ordinary AB adhesive usually does not have waterproof function. Therefore, before choosing glue, it is best to consult a professional glue engineer for professional advice.

AB glue has the following performance characteristics:
1. High adhesive strength, good toughness, oil resistance, water resistance, acid and alkali resistance, moisture resistance, dust prevention and other advantages;
2. Resistant to high and low temperatures, humidity, and atmospheric aging;
3. After curing, it has good electrical and physical properties such as insulation, compression resistance, and low shrinkage rate.
When using AB glue, the following precautions should be taken:
1. Due to the fast curing speed of AB glue, a small amount of mixing and trial should be carried out before use, and the usage skills should be mastered before large-scale mixing and use;
In the glue dispensing workshop, it is advisable to maintain room temperature at 25 degrees Celsius as temperature has a significant impact on the usage and curing time of the glue. In addition, when using air conditioning, it is important to avoid direct spraying of the air conditioning outlet onto the surface of the adhesive layer to prevent chemical reactions with agent B, which can lead to phenomena such as white mist, oil stains, and particles;
3. AB glue must be sealed and stored in a cool and ventilated place, avoiding high temperatures or direct sunlight. One of the main reasons for the yellowing of glue is that the glue cannot resist ultraviolet rays in sunlight or prolonged exposure to light.
