Novel Adhesive Solution Offers Curing in Light and Darkness and Bonding to Various Substrates
Including Opaque Materials Impermeable to Light
SINGAPORE, Nov. 6, 2024 /PRNewswire/ -- Dymax, a leading manufacturer of rapid curing materials and equipment, has been granted a patent for its HLCâ„¢ (Hybrid Light-Curable) adhesive platform. The new technology combines the optimal qualities of anionic polymerization and free radical chemistries into one formulation.
The newly patented HLC technology aims to improve the curing performance of urethane (meth)acrylate compositions commonly used to formulate coatings, adhesives, sealants, and inks. Primary advantages of HLCâ„¢ include fast cure, low-to-no blooming after proper light cure, better aesthetics, humidity resistance, and more flexible joints than ordinary cyanoacrylates.
While standard light-curing materials cure effectively using UV/Visible light, they often struggle in areas where the light cannot reach, leaving behind uncured areas. These shadowed regions not only compromise the reliability of the final product but can also weaken adhesive bonds over time. HLC addresses the issue of incomplete curing in dark areas with rapid moisture/contact cure capability. Bonding to a broad range of substrates, including opaque and light-blocking materials, is also possible.
Due to the composition of their light-curing component, Dymax HLC adhesives form a cross-linked polymer framework, enabling the successful bonding of small gaps or larger joints. Light-curing also reduces the risk of "blooming," a common issue with cyanoacrylates, where a white residue forms at the edges of bond lines when they react with ambient humidity. Light-curing can significantly reduce the risk of blooming as the material cross-links before the monomer can volatilize.
Dymax HLC-M-1000, the first adhesive in the series, is engineered for medical applications and meets several biocompatibility standards. Its light-curing capabilities allow for rapid curing in seconds with low-intensity light, optimizing performance even at ~20 mW/cm². With an extremely low viscosity of 3 cP, the material is capable of wicking into extremely tight bond joints not typically accessible with other, higher-viscosity adhesives.
"HLCâ„¢ technology fills a gap that many manufacturers using light-curing technology face when bonding opaque substrates," said Dr. Ahmet Nebioglu, Dymax Sr. R&D Director, Global. "It balances the need for rapid cure in light or darkness while addressing the issues of blooming, low impact resistance, and limited long-term moisture exposure. This new technology is a major breakthrough for adhesion quality in the manufacturing process."
This advancement may provide greater product reliability for end users through improved curing, stronger bonds, and enhanced durability, contributing to the overall quality of finished components.
For technical inquiries about patented HLC technology, a team of Dymax application engineers and system integrators is available to develop customized dispensing solutions for users, assist with material handling challenges, and support customers throughout the manufacturing process.

Patent Granted for Dymax's HLC™ Technology
HANOI, Vietnam, Nov. 6, 2024 /PRNewswire/ -- The engineering team of Viettel Cyber Security (VCS) has excellently won the championship for the second consecutive time at the Pwn2Own competition—the most prestigious security arena in the world. By successfully exploiting 9 security vulnerabilities in devices from major brands such as Canon, HP, Lorex, Synology, Sonos, QNAP, Lexmark, and TrueNAS, the VCS team from Vietnam outperformed competitors from Europe, Canada, and the United States to assert its position.
According to a report from the Zero Day Initiative on October 25, the VCS team scored 33 points after four days of competition, nearly double that of the second-place team, Team Cluck from the U.S., which had 17.25 points.
Security Targets Successfully Exploited by VCS at Pwn2Own
Pwn2Own is an annual network attack competition held since 2007, likened to the World Cup of the security community. This year's event featured eight categories for engineers to find and exploit security vulnerabilities, including Mobile Phones, Messaging Apps, SOHO Smashup (Small Office and Home Networking Systems), Surveillance Systems, Smart Home Devices, Printers, Smart Speakers, and NAS Storage Devices.
At Pwn2Own 2024, VCS experts successfully exploited 9 targets, including Lorex and Synology surveillance cameras; Sonos smart speakers; HP, Lexmark, and Canon printers; QNAP and TrueNAS Mini X network storage devices; as well as the SOHO Smashup networking systems category.
With this impressive result, VCS won a prize worth $205,000. Through the competition, VCS not only confirmed its superior security capabilities but also made significant contributions to discovering and enhancing the security of smart devices, especially as major manufacturers face increasingly complex and sophisticated threats in the digital age.
Developing Security Skills on AI-Integrated Systems
According to Mr. Ngo Anh Huy, head of the VCS team at Pwn2Own 2024, this year's competition posed significant challenges as devices were upgraded with more complex security measures, many integrated with AI to combat attacks. Exploiting AI-integrated devices requires the VCS team to have deep knowledge of AI in addition to traditional security skills.
"With the rapid development of AI, successfully exploiting these devices not only helps the team expand its security capabilities but also prepares them to respond to increasingly complex risks in the future. Success at Pwn2Own once again proves that Vietnamese experts are on par with their peers worldwide," Mr. Huy shared.
This year's event saw over 70 zero-day vulnerabilities discovered and exploited, with total prizes reaching $1,066,625. The success of VCS at Pwn2Own is not only a source of pride for Viettel Cyber Security but also enhances the status of Vietnam's cybersecurity industry on the international stage, opening up new opportunities and challenges in global cybersecurity.
About Pwn2Own
Pwn2Own is one of the most renowned and prestigious security competitions in the world, held annually by the Zero Day Initiative (ZDI) since 2007.
