Curing materials and equipment provider Dymax has been granted a patent for its HLC™ (Hybrid Light-Curable) adhesive platform. The new technology combines the optimal qualities of anionic polymerization and free radical chemistries into one formulation.

HLC technology aims to improve the curing performance of urethane (meth)acrylate compositions commonly used to formulate coatings, adhesives, sealants, and inks. The advantages of HLC include fast cure, low-to-no blooming after proper light cure, better aesthetics, humidity resistance, and more flexible joints than ordinary cyanoacrylates.
