UV Lamps
Photopolymerisation-based UV resins harden quickly thanks to the energy radiated by the ultraviolet devices.
These compounds are widely used to seal, join, or coat industrial materials, offering a distinctive advantage over conventional adhesives.
Their reaction does not occur due to oxygen, but only when exposed to a specific light wavelength.
This process can be further enhanced by thermal stimulation, ensuring a high degree of cross-linking, higher than that obtained only with UV polymerisation.
While requiring an initial phase of UV irradiation for optimal results, this high degree of cross-linking generates a higher glass transition temperature and increased resistance to moisture and chemicals.
UV Tunnel
Installation of a UV tunnel is essential for the use of these products, often associated with recirculating pallet lines to allow adequate radiation.
This technology is characterised by significant environmental, economic, and application advantages.
These include the absence of ozone, mercury, or harmful substances, low energy consumption, guaranteed duration of 20,000 hours, instant ignition, modular power, and compact dimensions to facilitate insertion into production machines.
The possibility of flanking multiple lamps allows for continuous radiation, maximising the effectiveness of the process.
Moulding
Plasma technology is used in combination with the dosing of adhesives and sealants on materials lacking the porosity necessary to achieve high levels of adhesion.
Plasma activation modifies the surface properties of non-polar materials such as plastics, metals, textiles, glass, recycled materials, and composites.
The treatment can be applied selectively, generating surface energy where needed, greatly improving the wettability of surfaces.
Plasma improves adhesiveness, chemical affinity, wettability, bio-compatibility, capillarity, and bond strength.
