UV glue and AB glue

Recently, customers often consult AVENTK on the website, asking what are the differences between UV glue and AB glue. Why do some applications use AB glue before, but now they start to use UV glue?

In fact, UV glue and AB glue from the composition to the curing way has a big difference, today AVENTK through an article, take you to understand the difference between UV glue and AB glue, you can also refer to when choosing glue!

The difference between the two

1. From the point of view of curing speed:

AB glue at room temperature about 28 degrees, curing time is larger, about 8 hours curing, you can have enough time to make a variety of modeling, completely hardening is best to give 24 hours. The higher the temperature, the faster the curing. In winter, it takes 2 to 3 days to cure at room temperature.

UV glue curing is not affected by temperature, in the UVLED curing machine irradiation generally a few seconds can be completed curing (different UV glue curing speed is different, the fastest can be in 1-2 seconds to complete curing)

2. From the perspective of curing method:

AB glue is two kinds of glue, by A(the main liquid) and B(curing agent) in proportion to the two to adjust, AB glue after the two reconcile, natural chemical reaction, curing with time, belongs to the thermosetting type.

UV glue is a single component glue, only 1 kind of glue, by ultraviolet light irradiation can be cured (generally with UVLED curing machine or UV mercury lamp), belongs to the light fixed glue.

3. From the perspective of transparency:

Most AB and UV adhesives have high fullness and transparency after curing. AVENTK UV adhesives are also available in other colors. There are also UV color changing adhesives (which change color by UV light).

4. Usage analysis:

UV glue is more applicable than AB glue, and the performance is stronger. Especially in industrial production, UV glue has the characteristics of fast curing speed, no solvent, strong adhesion, various types, more suitable for industrial automation production, in the camera module, optical communication, new energy, photoelectric, medical and other industries have a wide range of applications.
