Cavity Sealing Repair / CKD Applications

OE-Quality Repairs Made Simple

Repairing a vehicle to the original OE standards for performance and quality can be challenging because the equipment used in new vehicle assembly isn’t typically available in a repair facility. To help overcome that challenge, our product development team has created a range of process-friendly repair products like SikaBaffle®-278 for cavity sealing. Designed to cure quickly without the need for additional processing or heating equipment. SikaBaffle®-278 can easily be applied in
the repair shop, in Completely Knocked Down (CKD) plants,  but as well in the vehicle production, and ensures a fast, OE-quality repair.

SikaBaffle®-278 Filling Foam

A Fast, Reliable Solution for Automotive Body Cavity Sealing

In repair shops or CKD
assembly facilities, pre-formed acoustic parts can't be fitted into the vehicle cavity because the necessary equipment needed to properly heat the materials isn’t available. SikaBaffle®-278 is a ready-to-use, 2-component polyurethane foam, which cures very quickly at ambient temperature and reliably seals hollow cavities against noise, air, water and dust.

SikaBaffle®-278 can be used for manual application in vehicle production, as well as for repair and service solutions. Application is easy and safe because the two components are combined within the aerosol dispensing unit which has been specially designed to prevent excessive pressure build up.
