ENCLOSURE SEALING
BEYOND THE EXPECTEDSEALING SOLUTIONSFOR BATTERY HOUSINGSEALANTS FOR BATTERYEFFIECIENT APPLICATION WITH FAST CURINGEFFICIENCY REALISED WITH SIKA. Sealing is at the heart of what Sika do. From the very firstsealant method developed over 100 years ago, our core competency has remained the same, being amarket leader in the field of sealant technologies. Our long-term experience allows Sika to pull on thisexperience to produce new and odern solutions for the highly technical demands of the battery market.

Automated application of Sikaflex® sealants along withSika® Booster technology is commonplace in many industrial and automotive settings. With this level of expertiseavailable to our customers Sika is a reliable partner for
developing processes in the application of battery enclosure
sealing materials. Utilizing Sika® Booster technology allows
for fast and secure sealing of the battery pack so end of linepressure and leak tests can be conducted quickly allowing
the fast flow of product at end of line.

Enclosing the battery pack, also called battery lid sealing is
made secure with Sikaflex® materials. After application, thewet applied product will conform to many surfaces andallown for tolerances across the pack to achieve the seal
required from water, air and dust ingress. Sika can support
these applications with adhesion tests to the materials
used in the pack to ensure the right product is chosen for
the application.
