BondLynx is a revolutionary bonding agent that takes advantage of chemical crosslinking to form strong covalent bonds between a wide range of low-surface-energy polymers. This makes it an effective adhesive and textile strengthener for “impossible-to-bond” polymeric materials. It is also ideally suited to the electronics industry for photopatterning or stabilizing organic electronics and circuits.

BondLynx Gen-I, the original BondLynx molecule, is an electron-neutral aryl bis-diazirine crosslinker that can be activated by near-UV light (365 nm) or moderate heat, with a peak activation temperature of 137oC.

BondLynx Gen-III is an electron-rich aryl bis-diazirine crosslinker that can be activated with near-UV light (365 nm or 395 nm) or moderate heat, with a peak activation temperature of 109oC. In trials, BondLynx Gen-III has proven to be a significantly more efficient crosslinker for certain polymer substrates.

Several variations of BondLynx Gen-III have been developed and are available, each uniquely suited to specific applications and materials. Contact XlynX to learn more.

Introducing PlastiLynx, XlynX Materials’ newest and most versatile primer and adhesive product yet. Formulated as a multifunctional polymer crosslinker, PlastiLynx is a diazirine-grafted polyamine that can be used as a surface-activating primer or a single-agent adhesive, offering bonding solutions for even the most challenging polymer materials

Topically applied, PlastiLynx diazirine functionality is activated by UV light (365nm) or modest heat (110oC-120oC). This initiates the formation of highly active carbenes that insert themselves into C-H bonds on the surface of the polymer.

As a primer, PlastiLynx functionalizes the surface of low-surface-energy polymers so that they can engage with commercial cyanoacrylates, epoxies, and other adhesives to form strong bonds. In the same way, PlastiLynx can also be used to treat polymer surfaces and textiles so that they can engage with dyes and coatings, adding new functionality to materials.

As an adhesive, PlastiLynx can be used to create strong chemical bonds between polymer materials and textiles. Other applications, including the strengthening of textiles and the development of polymer-based alternatives to carbon fiber composites, are being explored and show remarkable promise.

The following demonstrates how PlastiLynx, once activated, forms a reactive layer along the surface of a polymer. Combined with bulk / commercial adhesives, PlastiLynx can create strong covalent bonds between hard-to-bond surfaces.

Currently in development, SteriLynx covalently bonds a powerful antimicrobial photosensitizer to surfaces and fabrics to passively kill bacteria and viruses. When exposed to visible light, SteriLynx-treated materials kill microbes by releasing singlet oxygen. And because it is chemically bonded to the surface, SteriLynx won’t wash off or leach into the environment!

SteriLynx promises to offer new enhancements to the safety and effectiveness of personal protective equipment (PPE), reducing the spread of bacteria and viruses. It may also be used to inhibit biofilm formation in marine and industrial settings.
