Cavity Sealing

Expanding Your NVH Options

Acoustic Insulation

Keeping noise levels low inside the vehicle is a key to achieving higher levels of passenger comfort. The SikaBaffle® and SikaSeal®-750/799 family of products helps improve vehicle acoustic performance by effectively sealing the car body and reducing noise transmission.

Simplified Assembly

SikaBaffle® and SikaSeal® are inserted during the assembly of the body structure and expand in the electro-deposited (E-Coat) oven to tightly seal the body cavity.

Improved Body Sealing for MOISTURE AND PARTICULATES

SikaBaffle® and SikaSeal® are also an ideal solution for preventing dust, moisture
and water from getting into the passenger compartment.
