Dymax Launches Hybrid Light-curable Adhesives
Dymax has launched HLC-M-1000, the first product in its new Hybrid Light-Curable (HLC) series of adhesives.
Hybrid Light-Curable technology is a patent-pending adhesive platform combining the best qualities of anionic and free radical chemistries into one formulation. HLC adhesives are the next generation of existing UVCAs and show the excellent physical and performance properties of Dymax light-curable adhesives and the rapid moisture/contact cure of anionics.
The use of contact curing makes it possible to bond instantly in low-light conditions and to a wide variety of substrates, including opaque and light-blocking materials.
The main advantages of HLC materials include fast cure under very low intensity, limited-to-no blooming with proper light cure, better aesthetics, humidity resistance (even without light), and more flexible bond joints than other CAs. It is not necessary for the substrate to be transparent, and exposure to light curing improves bond integrity while lessening blooming in exposed areas.
Less heat generation during cure, high gap-filling properties, and lessened stress cracking are other potential benefits of HLC materials. The materials also exhibit low-to-no surface tack and are safer to use. These attributes help contribute to productivity improvements and cost reductions in the assembly process.
The first product in the series, HLC-M-1000, is designed for medical device assembly. The adhesive meets various biocompatibility standards and is well-suited for bonding applications on catheters, tube sets, diagnostic and therapeutic devices, autoinjectors, and endoscopes. Its built-in moisture/contact cure feature enables complete adhesive curing in dark areas.
