During the actual use of UV glue, some friends sometimes encounter the situation where the UV glue does not cure completely, but they do not know the reasons that affect the curing effect of the UV glue and the solutions. As a professional manufacturer of UV adhesives, Dingxin has many years of experience in the UV adhesive industry. Today, Dingxin will analyze the main reasons for incomplete curing of UV adhesives from the following aspects. If you want to know more, please continue reading!

The main reasons are:

Some UV adhesives require a relatively high energy absorption capacity. If a UVLED curing machine with too low power is used, it may result in extremely slow curing or even no curing at all. In such cases, please check the power of the UVLED curing machine and replace it with a device of higher power if necessary.

2. The materials to be bonded are not very transparent or cannot be transparent at all, resulting in the attenuation or inability of UV light to penetrate the adhesive area, especially in the interior and crevices. It is recommended to change the direction of irradiation, or replace the material, or change the type of UV glue.

3. The influence of weather and environment, including high temperatures, strong light, and the entry of warm air from the south wind in spring, can cause changes in the properties of UV glue. It is recommended to seal the glue well during and after use and store it properly.

4. If the UV glue has deteriorated, etc., it is recommended to replace the glue. A simple way to check if UV glue has deteriorated is as follows: First, observe if its color has changed; Second, check if there are any abnormal particles, crystals, lumps or delamination inside the UV adhesive. Third, pour it out and let it flow down vertically to see if it flows evenly.
