Converting and Application
Pre-treatment involves painting aluminum and stainless steel with wash primer, and sandblasting or painting steel. Mix components A and B thoroughly before use. The pot life after mixing is about 30 minutes. Apply the mixture to the specified thickness and lay the constraining metal sheet in the wet layer. Support is needed for vertical applications during drying.

Safety Precautions
The B component contains isocyanides of MDI type. Use protective gloves and goggles. In case of eye contact, flush with water and seek medical attention. Remove skin splashes with soap and water or alcohol. Ensure good ventilation in working areas.

Performance
Drying time at +20°C is 8 hours, with maximum acoustical performance achieved after 5 days.
