Dymax Launches Hybrid Light-Curing Adhesives

Hybrid Light-Curable Adhesives from Dymax Dymax has launched HLC-M-1000, the first product in its Hybrid Light-Curable (HLC) adhesive series. Hybrid Light-Curable technology is a patent-pending adhesive platform that combines the best properties of anionic and free radical chemistry in a single formulation. HLC adhesives represent a new generation of UVCA products and exhibit the superior physical and performance characteristics of Dymax light-curable adhesives along with the rapid moisture/contact cure of anionics. The use of contact cure enables instant bonding in low-light conditions and to a wide range of substrates, including light-blocking and opaque materials. Key advantages of HLC materials include rapid cure at very low light intensities, substantial or complete elimination of bloom with appropriate light exposure for a more aesthetic appearance, moisture resistance, and more flexible bonds compared to other CAs. The substrate does not need to be transparent, and light exposure reduces bloom in exposed areas while improving bond integrity. Lower heat generation during cure, high void-fill capabilities, and reduced stress cracking are among the other potential benefits of HLC materials. Surface tack of the materials is negligible, and their use is safer. These properties help contribute to productivity improvements and cost reductions in the assembly process. HLC-M-1000, the first product in the series, is designed for medical device assembly. The adhesive meets various biocompatibility standards and is well suited for bonding applications on catheters, tubing sets, diagnostic and therapeutic devices, auto-injectors, and endoscopes. Its internal moisture/contact cure capability provides complete adhesive cure in dark areas. Source
