EMAX MS-40 Acoustic Adhesive Sealant — MS Polymer Technology for Construction and Acoustic Installations
EMAX MS-40 is a professional grade acoustic adhesive sealant based on advanced MS polymer technology. Suitable for acoustic panel installation, construction joinery and general building works, it delivers a permanent, flexible bond across almost every substrate used in modern construction. Isocyanate-free, paintable once cured and resistant to UV, moisture and extreme temperatures.
What Is an Acoustic Adhesive Sealant?
An acoustic adhesive sealant does two jobs at once — it bonds materials firmly while sealing gaps and junctions to prevent sound transmission. In acoustic installations this matters as much as the panels themselves. Gaps and poorly sealed edges are the most common cause of underperforming acoustic systems, allowing sound to bypass even the best materials.
EMAX MS-40 is an acoustic adhesive sealant that cures quickly on contact with atmospheric moisture, remains permanently elastic after curing and bonds on wet surfaces — making it reliable on real construction sites where conditions are rarely ideal.
Why EMAX MS-40 Is the Preferred Acoustic Adhesive Sealant for Installers
Bonds Without Compromising Acoustic Performance
When fitting acoustic panels, every junction and edge matters. EMAX MS-40 moves with the structure after curing, meaning it will not crack, shrink or pull away from panel edges over time. A sealant that fails at the joints undermines the performance of the entire acoustic system.
Isocyanate-Free Formula
Unlike older polyurethane adhesive sealants, EMAX MS-40 contains no isocyanates. According to the Health and Safety Authority, isocyanates are among the leading causes of occupational asthma. Choosing an isocyanate-free acoustic adhesive sealant reduces risk for installers working in occupied or enclosed spaces.
Paintable and Weatherproof
Once fully cured, EMAX MS-40 is paintable — ideal for acoustic installations where a clean finish is required. It remains unaffected by UV, sunlight, rain and extreme temperatures, performing equally well in interior and exterior applications.
