Low modulus prefabricated construction sealant MS141

Low Modulus. High Movement. Reliable Joint Protection.

MS141 is a low-modulus, weather-resistant MS polymer sealant developed for prefabricated construction and building joint sealing. It cures with moisture in the air to form a flexible elastomer with excellent elasticity, strong adhesion and long-term weather resistance. It is ideal for sealing interior and exterior wall joints, precast panel joints and curtain wall connections.

Key Benefits:

  • Low modulus design for better joint movement accommodation
  • High elongation with long-lasting elasticity
  • Excellent weather, water, UV and cold resistance
  • No oil leakage after long-term hot and cold cycles
  • Paintable after curing for better architectural finish
  • Odorless, benzene-free and formaldehyde-free for safer use

Performance Highlights :

  • Movement class: 25LM
  • Elongation at break: ≥450%
  • Max tensile strength: ≥0.6 MPa
  • Tensile modulus (23°C): ≤0.3 MPa
  • Elastic recovery: >70%
  • Vertical sag: <1 mm
