Exploring the Exceptional Applications of PUR Hot Melt Adhesive R3100 Series in Smartwatch Assembly

In modern society, smartphones and smartwatches have become indispensable devices for many individuals. Tex Year’s PUR hot melt adhesive R3100 Series, with its exceptional bonding performance, multi-material adaptability, and eco-friendly characteristics, stands out as the ideal choice for assembling smartphones and smartwatches. Its high bonding strength, impact resistance, long open time, and eco-friendly low-energy consumption features offer unparalleled advantages in the manufacturing process of these devices.


 

Multi-Material Adaptability and Exceptional Performance of PUR Hot Melt Adhesive

Tex Year’s PUR hot melt adhesive R3100 Series is suitable for various plastic materials, such as PA (polyamide), PC (polycarbonate), PMMA (polymethyl methacrylate), ABS (acrylonitrile butadiene styrene), as well as metals like stainless steel and aluminum, and inorganic materials like ink surfaces on glass. This wide adaptability ensures robust bonding for every component of a smartwatch, guaranteeing structural stability during daily use and even under extreme conditions.

Furthermore, the R3100 Series exhibits outstanding bonding strength and impact resistance, fulfilling rigorous test requirements such as drop and roll tests. This makes it the ideal choice for electronic devices used in outdoor activities, offering users a more durable and reliable product experience.
 

Unique Chemical Formula Enhances Product Reliability

PUR hot melt adhesive R3100 Series incorporates reactive functional groups. After undergoing moisture-cured crosslinking, the adhesive’s physical properties, such as tensile strength and toughness, are enhanced. It also effectively reduces the occurrence of CO2 bubbles during the curing process, a common issue with traditional PUR hot melt adhesives.  The unique formula of the R3100 Series effectively minimizes bubble formation, ultimately improving the overall reliability of the product.

High Efficiency and Environmental Friendliness Go Hand in Hand

The R3100 Series can cater to different assembly process requirements. Its 100% solid content, solvent-free nature, and non-heated curing process ensure low energy consumption, aligning with global Sustainable Development Goals (SDGs).  This not only simplifies operations and promotes eco-friendliness but also contributes to higher efficiency and stability in the production process.

In specific applications for smartwatches, the R3100 Series demonstrates its exceptional performance. For instance, when bonding the display to the watch case, the R3100 Series' high transparency and stable adhesion ensure both robust bonding and an aesthetically pleasing appearance.  When fixing the frame together, the R3100 Series offers strong bonding and waterproofing properties, guaranteeing the watch's reliability across different usage environments. When bonding sensor modules, the R3100 Series exhibits high precision and impact resistance, ensuring the accuracy and durability of the sensors.
