ThreeBond 3177 : a UV & moisture curing resin

15/06/2026
needle What if manufacturers no longer had to choose between the speed and transparency of UV-curing resins and the versatility of instant adhesives ? ThreeBond 3177 bridges this gap by combining both technologies into a single high-performance adhesive solution.
UV-curing resins are among the most advantageous sealing and bonding solutions available today, thanks to their exceptionally fast curing speed and excellent optical transparency. Widely used across industries such as medical devices, electronics, and industrial manufacturing, they provide reliable bonding, sealing, and protection for a wide range of components and assemblies.

Capable of curing within seconds when exposed to UV light, ThreeBond 3177 goes beyond the capabilities of a conventional UV-curing resin. Combining UV-curing and instant adhesive technologies, it also benefits from moisture-curing properties, ensuring complete curing even in shadowed areas where UV light cannot reach. This unique hybrid formulation delivers outstanding resistance to both humidity and heat, making it suitable for demanding environments.

One of the key advantages of instant adhesives lies in their ability to bond a wide variety of substrates, including plastics, elastomers, and rubber materials that are often considered challenging to assemble. By combining the transparency and rapid curing of UV resins with the versatility and strong adhesion of instant adhesives, ThreeBond 3177 offers an efficient solution for complex bonding applications. The result is a versatile adhesive that simplifies assembly processes, increases productivity, and expands design possibilities for manufacturers across multiple industries.

Application example


— Needle-to-Hub bonding

One of the key applications of ThreeBond 3177 is the bonding of needles to their hubs in medical devices. Developed according to ISO 10993, this resin is suitable for medical application. Needle-to-Hub assembly requires a highly reliable adhesive capable of providing strong adhesion to dissimilar materials while ensuring precise positioning and rapid processing.


Thanks to its fast UV curing, ThreeBond 3177 significantly reduces production times, while its moisture-curing mechanism guarantees complete curing in areas where UV light may be obstructed. Its excellent adhesion properties, combined with its resistance to moisture and sterilization-related conditions, make it an ideal solution for the manufacturing of safe and durable medical assemblies.

— Optical bonding



Optical assemblies require adhesives that combine excellent transparency with precise and reliable bonding performance. Thanks to its high optical clarity and rapid UV curing, ThreeBond 3177 is particularly well suited for the assembly of optical components such as lenses, light guides, sensors, and display elements. Its fast curing speed enables efficient production processes while minimizing component movement during assembly.


Optical transceiver

In addition, its dual-curing technology ensures complete curing even in shadowed areas, improving bond reliability and long-term durability. The result is a strong, transparent bond that preserves optical performance while meeting the demanding requirements of modern electronic and optical devices.


Camera module

ThreeBond 3177 is suitable for bonding a wide range of optical components, including lenses, optical transceivers, optical sensors, and camera modules. Its excellent transparency and fast UV curing help maintain optical performance while enabling efficient and precise assembly.
