The "EJ Tape" is a tape that has a self-adhesive layer laminated onto a vulcanized rubber tape. By treating the surface of the substrate with a dedicated primer and simply applying and pressing it down, it can be bonded. After installation, the temperature rise of the tape surface promotes the curing of the adhesive layer, demonstrating strong adhesion. There is no concern about uneven application like with adhesive methods, and since the specified adhesive thickness can be secured, stable adhesion and water tightness can be ensured. 【Features】 ■ Easy to install ■ Stable finish ■ Strong adhesion *For more details, please download the PDF or feel free to contact us.
