Ideal for sealing pillars, posts, cavities, and voids where air, wind noise, or vibration enters the cabin.
Expands up to 10× its original volume, allowing efficient filling of irregular spaces and complex vehicle structures.
Matches OEM sound‑deadening foams and retains its shape without shrinkage over time.
Will not absorb moisture or contribute to corrosion — suitable for long‑term interior and exterior cavity sealing.
Extremely fast work time (10 seconds) and full expansion in 3 minutes for high‑efficiency repairs.
Paintable in just 10 minutes, making it ideal for quick turnaround refinishing.
Thin viscosity requires careful dispensing; avoid pneumatic applicators to prevent uncontrolled flow.
