As an adhesive, UV glue is essentially a chemical substance and is often used in the production and manufacturing of modern industrial products. In practical use, we often encounter situations like this: during the process of bonding components with UV glue, it is found that the components are not well bonded or need to be separated and disassembled for re-bonding. So, how can we separate the cured UV curing adhesive? It is necessary to adopt different methods for separation according to the characteristics of different UV glues and the material properties of the bonded components. Regarding the specific operation steps, the application engineers of Yantai Chemistry have sorted out several points for your reference as follows:

1）Heating with a hair dryer: The strength of UV glue will significantly decrease at high temperatures. By heating the bonded part with a hair dryer or an oven and raising its temperature, it will be easier to remove.

2）Boiling in high-temperature water: You can use clean water or alkaline water with an appropriate amount of alkali added. After boiling in water, the strength of the glue will decrease significantly.

3）Soaking in solvents such as acetone or ethanol: Under the action of organic solvents, the strength of the glue will gradually decrease.

In addition to the above methods, in some cases, it may be relatively difficult to separate or disassemble the UV glue. For example, situations such as the high bonding strength of the UV curing adhesive or a large bonding area are more challenging to handle. If the customer’s product has a high rework rate or the materials are of high value, when choosing a UV glue, it is essential to clearly state the application and process requirements. On the one hand, it is necessary to meet the customer’s bonding requirements, and on the other hand, the reworkability of the product should be considered. Make adjustments within a certain range according to the specific situation to obtain empirical data for normal use, and these empirical data should not be changed casually during the production process. For any application and glue application issues regarding UV glue, you are welcome to consult the engineers of Yantai Chemistry.
