Henkel offers Sonderhoff Fermapor K31, a two-component room temperature cross-linking polyurethane sealing foam for battery packs in electric vehicles. The sealing foam protect the electric batteries against moisture, corrosion, and dust. The product also dampens the vibrations and is temperature and chemicals resistant on polyurethane material specifics.
Two-component Weather-Resistant Sealing Foam
The die-cast aluminum housings for holding the electric batteries are sealed efficiently, precisely, and securely using FIPFG (Formed-In-Place-Foam-Gasket) technology. The CNC-guided mixing head of the Sonderhoff mixing and dosing machine moves along the housing geometry and applies the two-component polyurethane sealing foam Sonderhoff Fermapor K31 with precise contours. After foaming, a seamless foam gasket is produced which cures at room temperature.
The elastic foam cell structure of the seal is compressed when the battery housing cover is screwed tight. Thus, the housing and cover are sealed to each other. The resetting ability of the foam sealing allows the housing to be opened and re-closed repeatedly for maintenance purposes.
The sealing effect of the housing seal is maintained by the consistently good compression of its foam structure. The housing is sealed, and the batteries are protected against splash water and weather influences.
