Can all UV glues for bonding metals in computer production in the electronics industry be cured by LED UV?
News 2024-08-09
In the computer production of the electronics industry, most UV adhesives for bonding metals can be cured by LED UV, but not all are applicable. The specific situation depends on the composition and formula of the adhesive. Here is the specific analysis:
Applicable situations: Many modern UV adhesives adopt a photoinitiator system sensitive to LED UV light sources. For example, common free radical photoinitiators, including derivatives such as camphorquinone and benzophenone, can be effectively excited under the specific wavelength of LED UV light sources to generate free radicals, thereby triggering the polymerization reaction of the adhesive and achieving curing. This type of adhesive is usually suitable for LED UV curing and can be used for bonding metal parts in computer production, such as bonding the metal frame of the computer case and other components.
Non-applicable situations: Some UV adhesives with special formulas may be designed for traditional mercury lamp UV curing systems. Their photoinitiator systems are not sensitive to the wavelength of LED UV light sources, or the adhesive formula contains more additives that absorb or block LED UV light, so they are not suitable for LED UV curing.Before using, it is best to consult the glue supplier first to understand whether the UV glue used is suitable for LED UV curing, and verify the curing effect through small-scale experiments to ensure the bonding quality of metal parts in computer production.
