Radiation curing technologies are expanding rapidly on an industrial scale, as shown by the increase in speciality monomer production in the past twenty years.?
This new technology uses light irradiation to initiate photochemical and chemical reactions in organic materials, leading to the formation of new polymeric materials.?
Nowadays, UV technologies continue to develop, which is rapidly driven by the number of economic and environmental advantages they provide over traditional thermal curing processes in these same applications. Such as:?
What does UV-curing do??
UV lamps irradiate the surface of the coated adhesive. This activates photoinitiators that initiate chain polymerisation. Without polymerisation, the adhesive would have no structure. By structure, we mean the ability of an adhesive bond to adhere to a substrate.?
Do I need Corona Treatment?
The Corona treatment is one of the methods used to "activate" a surface film through an electrical discharge. Increasing the surface energy of a plastic film improves the adhesion of the adhesive. It's mainly used for materials such as PPE, PE, HDPE, EVA and so on. These materials have particularly low surface tension.
Now that we are on the same page, as promised, let’s look at the main features of UV-cured.?
1. Solvent-free
The main advantage and the most sought-after is to drastically reduce the environmental impact. This coating method enables the manufacturer to get rid of solvent in the production process. We talked a bit more about this specific benefit here:
2. Non-irritating to the skin
OECD-Organization for Economic Co-operation and Development certifies that UV-cured based adhesive solutions are harmless to the skin. This makes it ideal for medical and cosmetic enterprises looking to develop such products.?
3. Diversification
In many industries, acrylic adhesives are widely used because they possess superior properties. Such as:

4. Direct contact with foods?
Tested by ISEGA- Industry studies and disposal company. The German organization tests the safety for use as food packaging of packaging materials. Ideal for the fast-growing food packaging industry and any organization operating in this field.
5. Resistance to seawater
BS 5609- certified. This is a specification for “printed pressure-sensitive or self-adhesive coated labels for marine use”. Organizations operating in the marine cargo shipment or the sailing industry can benefit from this feature.
6. High resistance to ageing
If you need a long-lasting adhesive solution, you’ll prime UV-cured. Industries like automotive and building prefer UV-cured for this reason.?
7. High resistance to water, humidity and weathering
Depending on their GTT - Glass Transition temperature - that allows them to have good resistance to low temperatures and excellent behaviour in high temperatures.
8. Applications
Many UV-adhesives have an ISO-10993 certification. Meaning that they don't have any toxicological effect on human skin. Due to their solvent-free nature, and lower price than solvent-based adhesives. They are widely employed.
