UV/Visible Cationic Epoxies

Light curable cationic epoxies from Panacol-Elosol absorb light energy to generate ions that initiate an ionic polymerization process. Advantages of this process are dry, tack-free surface, no shrinkage, low odor, better adhesion, abrasion and chemical resistance, high strength, extreme clarity, and moisture resistance. NEW, LED curable epoxies are now available!

As their exclusive distributor for the Americas, Tangent offers light curable epoxies from Panacol-Elosol. Panacol-Elosol GmbH is a member of the Honle Group headquartered in Germany, and has been formulating and manufacturing adhesives for over 30 years.

With an expertise in epoxy development, Panacol’s product line includes innovative light curable epoxies based on cationic cure. Unlike light curable adhesives that utilize free radicals to initiate the polymerization process, light curable cationic cure epoxies absorb light energy to generate ions that initiate an ionic polymerization process. This translates to the following advantages:

  • Light curable cationic epoxies are not subject to oxygen inhibition, which means the cured adhesive surface is dry and tack-free.
  • Light curable cationic epoxies have little or no shrinkage during cure.
  • Light curable cationic epoxies are low odor.
  • Light curable cationic epoxies typically offer better adhesion than other light curable adhesives.
  • Light curable cationic epoxies are abrasion and chemical resistant.
  • In the event that exposure to UV light curing energy is terminated prior to the light curable cationic epoxy becoming fully cured, it will continue its polymerization without light energy (in the previously illuminated area) until full cure is achieved

Light curable cationic epoxies combine proven epoxy durability with the processing speed of today’s light curable adhesives. Epoxy bonds possessing high strength, extreme clarity, and moisture resistance can be developed in seconds using a UV/Visible light curing process. These products are ideally suited for applications that are subject to environmental stresses, higher operating temperatures, and extreme wear.

Now, LED curable cationic epoxies are available. These new formulations can be cured with LED curing systems at 365nm wavelength.
