Soundac PU-D30

Product catalog summary

Description
Soundac® PU-D30 is a two-component polyurethane compound designed for constrained layer applications on steel and aluminum in non-horizontal objects and walls. It forms a viscoelastic damping layer that significantly reduces noise generated by structural vibrations, offering a high loss factor over a wide temperature and frequency range. It can be easily combined with Soundac® AS sound-absorbing foams.

Application
Soundac® PU-D30 is used for anti-drumming of walls and non-horizontal floors, reducing vibration levels in steel structures and machines. The product is readily available in stock.

Packaging
Available in two packaging sizes: 4 kg A + 0.5 kg B and 8 kg A + 1.0 kg B.

Converting
Surface pre-treatment involves painting aluminum and stainless steel with wash primer, and sandblasting or painting steel. Components A and B must be thoroughly mixed before use, with a pot life of about 30 minutes. The mixture can be trowelled to the specified thickness, and the constraining metal sheet should be laid down in the wet layer. For vertical applications, support is needed during drying.

Safety
The B component contains isocyanides of the MDI type. Protective gloves and goggles are required. In case of eye contact, flush with water and seek medical attention. Skin contact should be cleaned with soap and water or alcohol. Ensure good ventilation in working areas.

Soundac® PU-D30 Two-component sandwich anti drumming for walls Description Soundac® PU-D30 is a two component polyurethane compound designed for use in constrained layer applications of steel and aluminium in non horizontal objects and walls. ® The Soundac PU-D30 viscoelastic damping layer is a specially formulated polyurethane polymer designed to produce, together with the steel construction and a steel sheet constraining layer, a final structure with very high loss factor over a wide temperature and frequency range. This dramatically reduces noise generated by vibrations in the structure. The PU-D30 is well suited and easy to combine with ® the Soundac AS sound absorbing foams. Application Soundac® PU-D30 is used in anti drumming of walls, non horizontal floors reduced vibration levels of steel structures and machines. Stock These materials are always on stock.
