What are UV curing systems ?

Adezif offers a range of UV curing equipment for UV curing adhesives, i.e adhesives containing photoinitiators. The UV light or visible light emitted by these devices triggers the photopolymerization of the adhesive, also known as "radiation curing".

 

UV curing is a method frequently used for assembly applications where flexibility, mechanical strength and transparency are required:

  • Glass industry, POS, medical or optical equipment, electronics, household appliances, aeronautics...
  • Assemblies with at least one UV-transparent material: glass-glass, glass-plastic, glass-metal...

 

This process requires little working space and is much faster to set up than thermal curing, which allows industrial operators to gain considerably in productivity and quality control.

 

 

There are two main types of UV curing technology :

  • Bulb technology: "traditional" UV lamps and equipment
  • LED technology : More and more popular in the industry,  LED UV curing lamps allow an efficient curing of adhesives and have a much longer life span (on average, 20000 hours vs. 1000 hours for bulb devices) 

 

Adezif provides UV-A, UV-B, UV-C and visible light curing systems, suitable for both manual applications and assembly lines.

How to choose your UV curing machine ?

Three key parameters to choose you UV curing lamp:

 

UV spectrum:

It must target the photoinitiators contained in the UV curable adhesive. There are three main wavelengths:

  • 352 nm (UV-A)
  • 365 nm (spotting, deep polymerization)
  • 405 nm (surface mechanical strength).

 

Always test before final bonding. Even a multi-purpose UV lamp may be more or less effective for a particular spectrum and depending on the adhesive.

 

UV spectrum

 

Surface specifications:

  • Choose your UV lamp or curing unit according to the dimensions of the bonding surface. Regular exposure ensures even curing and avoids creating tensions or defects in the final assembly.
    E.g.: UV light projectors are suitable for short lengths. UV tubes are made for longer surfaces.

 

  • Check the transparency and properties of the materials you wish to bond. Some plastics, such as polycarbonate or PMMA, may have an anti-UV treatment, which slows down or even prevents polymerization.
