On our company website, we introduce a usage chart for anti-loosening processing of screws. Anti-loosening processing refers to the coating of the screw threads (spiral part) with resin or adhesive in advance. Just by assembling, it effectively prevents loosening, falling off, and provides waterproofing. There are types for adhesion, resistance, conductivity, and chip debris absorption, and we have listed recommended types for each category, such as "for places you don't want to loosen" and "when you want to reuse." Please make use of this when considering implementation. 【Listed Items (Partial)】 ■ Strong adhesion! For places you don't want to loosen? ■ Removal for maintenance! When you want to reuse? ■ Resin is insulating! What about anti-loosening with conductivity? ■ Concerned about chip debris! How to capture and absorb chip debris to prevent intrusion? *For more details, please refer to the PDF materials or feel free to contact us.

Conventional processing aimed at capturing molding debris has managed to collect the debris, but no measures have been taken to address loosening after tightening... Nissei Technica's TPX processing solves this issue, not only capturing and adhering to molding debris but also exhibiting a bonding effect after a certain period of time post-tightening, resulting in high return torque. 【Features】 ■ Effectively captures molding debris, preventing it from falling into manufactured products! ■ After tightening, it exhibits a strong anti-loosening effect! ■ Color identification is possible, improving production management. ■ High chemical resistance and insulation. ● For more details, please download the PDF or feel free to contact us.

The "PA-S Processing (Nylon Resin)" is an enhanced version of the conventional "PA Processing," utilizing a special nylon resin to create a locking treatment for screws that excels in adhesion and repeatability. This coating method firmly adheres the film around the entire screw, demonstrating a high locking effect even with repeated use. Since it uses a special nylon resin, it offers excellent oil resistance and chemical resistance, eliminating concerns about corrosion of screws, hinges, etc. 【Features】 ■ High repeatability ■ High durability ■ Chemical resistance ■ Torque adjustment function ■ High adhesion For more details, please refer to the catalog or feel free to contact us.

"NDS-EL processing" is a microcapsule-type locking treatment that enables two effects: conductivity and adhesion, with excellent locking performance. Conductive fillers are blended into the locking agent. The reason current flows through the locking agent made with synthetic resin is that the fillers connect, creating a conductive path. It can be used even in harsh temperature environments. 【Features】 ■ Special material blend ■ Achieves conductivity and adhesion simply by tightening ■ Environmentally friendly ■ Improved safety and reliability ■ Adjustable strength to prevent loosening 【Product Examples】 Small electronic devices such as cameras and Walkmans For more details, please refer to the catalog or feel free to contact us.

The "EL-S processing" is an enhanced version of the conventional product "UG-EL processing," achieving conductivity and dustlessness by combining conductive materials with resin, specifically designed for screw locking applications. To impart conductivity to insulating synthetic resin, it is common to incorporate conductive fillers. The filled conductive fillers bond with the conductive resin to form a strong coating. This also provides a locking effect. We are confident that we can address issues such as "wanting to impart conductivity to screws that secure the base" or "concerns about loosening while wanting to conduct electricity," thereby contributing to improved safety and reliability. 【Features】 ■ Conductivity: 8.25×10^-3Ωm ■ Approximately 47 times increased conductivity compared to "UG-EL processing" ■ Dustless ■ Minimal debris during tightening ■ Locking effect For more details, please refer to the catalog or feel free to contact us.
