MS sealant for construction is a high-performance, elastic sealing material primarily formulated with silane-terminated polyether (MS Polymer) as the base.
It is blended with fillers, plasticizers, and other functional additives to deliver excellent sealing performance.
Available in one-component or two-component systems, MS polymer sealant is environmentally friendly, solvent-free, and virtually odorless making it ideal for both interior and exterior construction applications.
mS polymer sealant Main uses
1. Construction engineering
- Used for sealing building gaps, door and window frames, window sills, interior walls and other parts.
- Suitable for prefabricated buildings, concrete joints, building decoration, etc.
- Can be used for bonding building materials such as glass, aluminum, concrete, etc.
2.Automobile manufacturing
- Used for bonding body parts (such as doors, roofs, luggage compartments, etc.).
- Provide structural support and sealing effects.
3.Electronic appliances:
- Used for electronic component packaging, electrical housing bonding, radiator fixing, etc.
- Has good insulation properties and high temperature resistance.
4. Ship and marine engineering:
- Used for sealing of marine electronic equipment and encapsulation of marine detection equipment.
- Resistant to seawater corrosion, suitable for long-term immersion environment.
5. Industrial manufacturing:
- Used for mechanical equipment assembly, chemical equipment sealing, etc.
- Has high strength and chemical corrosion resistance.
mS sealant characteristics
1. Environmental protection:
- No solvent, no formaldehyde, low volatile organic compounds (VOC), harmless to the environment and human health.
2. Adhesion performance:
- Has good adhesion to a variety of substrates (such as metal, glass, concrete, wood, etc.).
3. Elasticity and weather resistance:
- After curing, it has high elasticity and can absorb and compensate dynamic loads.
- Strong weather resistance, can be used for a long time under extreme climatic conditions.
4. Convenience of construction:
- Single-component products do not need to be mixed and are easy to use.
- Fast curing speed, can be cured at room temperature.
5. Other features:
- Neutral curing, no corrosion to substrate.
- Waterproof and moisture-proof, can be used in humid environments.
There are a large number of assembly joints in the prefabricated exterior wall of PC building, and it easyto cause water leakage.
Use the low modulus MS polymer sealant,MS sealant for construction can maintain buildingintegrity under displacement and excellent water gas seal.
