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
