SGM Prime Onyx Atom —premium vibration dampener with thickened 120 µm aluminum foil. The advanced butyl rubber mastic retains its elasticity and damping properties across an extended temperature range from –40°C to +140°C, offering enhanced adhesion to metal. The mounting side is protected by silicone-coated paper.

In the updated from the beginning of 2026 version of the material, the adhesive composition has been improved: increased adhesion ensures instant bonding and reliable fixation without preheating. The adhesive upgrade has made it “smart”: the “smart” adhesion of SGM Prime materials allows for adjustments during installation, with adhesion increasing by 25% within 15–20 minutes and by 60–80% or more after 24 hours.

The material features a matte satin aluminum foil treated with «Prime Satin» technology. This technology creates a developed micro-rough surface structure, providing a mechanical bonding effect with the mastic. This significantly enhances interlayer adhesion strength and completely eliminates the risk of dust or moisture penetrating between the second layer of sound absorber and the foil of the primary damping layer.

The material now features a new design and new packaging.

With a thickness of 2.1 mm, this material is ideal for treating vehicle floors, roofs, dashboards, and plastic fender liners, where precise geometric conformity and effective vibration damping are required without overloading the structure. Thanks to its balanced weight, the material is also effective for treating doors and front panels without placing excessive strain on body components. For optimal results, installation with a roller is recommended — the material offers enhanced adhesion and can be applied at temperatures as low as +10°C.
