UV LED curing technology provides a more consistent and reliable process without damaging or discloring heat-sensitive components.
Ultraviolet (UV) light-emitting diode (LED) curing offers many benefits for bonding and coating applications in the touchscreen manufacturing segment. It provides a more consistent and reliable process without damaging or discoloring heat-sensitive components.
UV curing is a photopolymerization process that uses UV energy to change a liquid to a solid. Upon absorption of the UV energy, the photoinitiator (PI) produces free radicals that initiate crosslinking with binders (monomers and oligomers) in a polymerization reaction to cure or solidify the ink, coating, or adhesive, usually in a few seconds.
Originally introduced in the 1960s, today’s manufacturers use UV curing for a variety of applications—from graphic arts printing to automotive headlamp coating and more. In fact, the UV curing market continues to grow as it displaces water- and solvent-based thermal drying processes due to increased productivity, higher quality and performance, and environmental benefits. |
