How to use
Position the LOCTITE® RB EV 9740 cord on the flange of the battery tray, ensuring the release paper is on the upper side, and gently press down. The adhesive properties of the cord will hold it in place. Continue pressing the cord onto the flange, ensuring complete coverage of the sealing area. At the endpoint, overlap the cord by at least 2 cm.
Check that the cord is properly pressed on, and then carefully remove the release paper.
Carefully place the battery cover on the battery housing, ensuring that the sealant is well pressed in place.
Insert the fasteners into their designated holes and evenly tighten to ensure uniform pressure. Make sure the cord remains in its designated position.
Carry out an airtightness test with special testing equipment to meet the initial IP 67 requirements. You can do this directly after assembly of the cover.
FAQ
LOCTITE® RB EV 9740 delivers a strong, reliable seal with exceptional adhesion to multiple substrates, making it ideal for battery repairs.For additional technical details, please reach out to us.
For optimal adhesion, the substrates on the battery tray or lid should be clean, dry, and free from contaminants like dust, grease, or other adhesion inhibitors. We recommend using our professional cleaner, TEROSON® VR 10 [link to VR10], to ensure thorough cleaning of the surfaces. LOCTITE® RB EV 9740 provides excellent adhesion to various substrates, including steel, aluminum, and composites such as SMC. For more detailed information, please refer to the Technical Data Sheet (TDS).
LOCTITE® RB EV 9740 does not require chemical curing. With this product, air leakage and ingress protection tests can be conducted immediately, providing a seal and protection right after the assembly of the EV battery pack. This significantly reduces working time and enhances workshop efficiency. For more details, please contact us.
