Henkel Introduces LOCTITE® 406 Instant Adhesive: A Breakthrough Solution for Efficient Multi-Material Bonding

With excellent flow control and strong bonding to various substrates, LOCTITE 406 enhances production efficiency and product reliability in electronics, medical, and precision manufacturing industries.

Henkel, a global leader in adhesive technologies, today highlighted its product, LOCTITE® 406 low viscosity instant adhesive. Known for its rapid curing, broad material compatibility, and excellent flow characteristics, LOCTITE 406 is an ideal choice for solving diverse industrial bonding challenges, particularly in applications requiring fast assembly and involving multiple substrates.

LOCTITE® 406 is an ethyl cyanoacrylate-based instant adhesive. One of its key features is its ability to form high-strength bonds on a wide range of substrates, including many difficult-to-bond plastics (such as plasticized PVC, rubber), as well as metals, and elastomers. Unlike traditional adhesives that may require surface preparation or long curing times, LOCTITE 406 develops high strength in seconds under slight pressure, significantly improving assembly line efficiency.

• Rapid Cure and High Strength:​ On most substrates, LOCTITE 406 achieves handling strength in 5 to 30 seconds and quickly reaches its final strength, effectively shortening production cycles.
• Excellent Material Compatibility:​ It provides reliable bonds on common materials like metals and rubber, as well as on acid-sensitive engineered plastics (e.g., POM, TPE/TPU), preventing bond failure due to material incompatibility.
• Superior Flow and Gap-Filling:​ Its low viscosity allows it to wick quickly into tightly mated joints via capillary action, making it perfect for bonding small, precision parts that require high strength. Its moderate gap-filling capability (approx. 0.15mm) ensures effective bonding in micro-clearances.

The versatility of LOCTITE 406 makes it widely applicable across various industries:

• Electronics Manufacturing:​ Used for securing miniature speaker magnets, bonding rubber keypads, fixing cable terminals, and assembling plastic housings. Its fast-curing nature is ideal for high-speed production lines.
• Medical Devices:​ In the assembly of disposable medical devices (e.g., syringes, catheters) for bonding plastic components and rubber seals. Its reliability and rapid cure meet the high standards for hygiene and efficiency in the medical industry.
• Automotive Components:​ Used for bonding plastic and rubber parts in interiors or securing small electronic components like sensors.
• General Manufacturing & Repair:​ Serves as an efficient tool for emergency production line repairs, laboratory prototyping, and everyday DIY projects.
