In construction, automotive and industrial manufacturing sectors, sealing and bonding technologies are gradually improving. One of these improvements is the development of MS polymer sealant—an eco-friendly and high-performing sealant which is now superseding silicone and polyurethane based sealants. In this article, I provide a detailed explanation of MS polymer sealant—from its composition, benefits, applications to tips on making the right choices regarding them.
What is MS Polymer?
MS polymer sealants are made from a high-performance polymer modified with silane groups called MS polymer. It is produced in a single or dual component form. While it retains the strength of adhesion provided by polyurethane sealants, it is also as weather resistant and environmentally friendly as silicone sealants.
Key Advantages of MS Polymer Sealant
-
Eco-friendly and Non-toxic
MS polymer sealants contain no isocyanates, solvents, or harmful plasticizers, and have very low VOC emissions, fully complying with EU REACH and RoHS environmental standards. -
Excellent Adhesion
They bond strongly to various substrates such as metal, glass, wood, concrete, and plastics without the need for primers, serving both sealing and structural bonding functions. -
Outstanding Weather Resistance and Durability
MS polymer sealants resist UV radiation, rain, and temperature cycling, making them ideal for outdoor use. -
Bubble-free and Non-yellowing
Unlike PU sealants, MS polymer sealants do not bubble during curing in humid environments, resulting in a smooth and aesthetically pleasing surface. -
Paintable and Sandable
After curing, the surface can be painted or sanded, suitable for applications where appearance matters.
Applications of MS Polymer Sealant
-
Construction
Glass curtain walls, aluminum panel joints, stone joint filling, window and door frame sealing, roof waterproofing, and more. -
Automotive
Car body joining, roof seam sealing, door liner bonding, vibration damping, and sound insulation. -
Rail Transit and Marine
Cabin sealing, floor bonding, waterproofing, and soundproofing. -
Industrial Assembly
Home appliances, electronics, solar panel encapsulation, industrial container sealing, etc.
MS Polymer Sealant vs. Other Sealants
| Property | MS Polymer Sealant | PU Sealant | Silicone Sealant |
|---|---|---|---|
| VOC Emission | Very Low | Medium | Low |
| Adhesion Strength | Excellent | Excellent | Moderate |
| UV Resistance | Excellent | Moderate | Excellent |
| Paintability | Good | Good | Poor |
| Elastic Recovery | High | Medium | High |
| Application Range | Indoor & Outdoor | Requires Care | Outdoor Suitable |
How to Choose the Right MS Polymer Sealant?
When selecting an MS polymer sealant, consider the following:
-
Modulus and Movement Capability: Choose between high elasticity or structural bonding types based on your environment.
-
Curing Speed: Fast-curing products are preferred for projects with tight schedules.
-
Paintability: Select paintable and sandable options for visible or decorative surfaces.
-
Brand and Quality: Opt for internationally certified and reputable brands such as Sika, Bostik, Den Braven, or Soudal.
Conclusion
Experts highly regard MS polymer sealant for its environmental impact, longevity, and superior performance, making it one of the best sealants on the market. This sealant perfectly suits those who need a solution for multiple substrates, framed weatherability, and long-term compliance with eco-friendly construction standards.
