MS Sealant vs. Polyurethane Sealant: Key Differences, Pros & Cons
What is MS Sealant?
MS Sealant (Modified Silane/Silyl-Terminated Polymer) is a next-generation adhesive offering superior flexibility, UV resistance, and eco-friendly performance. Designed to replace traditional polyurethane sealants, it’s ideal for dynamic joints, outdoor applications, and sustainable projects.
What is Polyurethane Sealant?
Polyurethane Sealant is a rigid, chemical-resistant adhesive suited for heavy-duty industrial use. However, its limitations in flexibility, UV stability, and environmental impact make it outdated for modern applications.
MS Sealant vs. Polyurethane: Advantages & Disadvantages
| Feature | MS Sealant | Polyurethane Sealant |
|---|---|---|
| Flexibility | ✅ Retains elasticity long-term | ❌ Hardens, cracks over time |
| UV/Weather Resistance | ✅ No yellowing, no additives needed | ❌ Degrades without UV stabilizers |
| Chemical Resistance | ⚠️ Moderate (resists water, mild chemicals) | ✅ Excellent (oils, fuels, solvents) |
| Eco-Friendliness | ✅ Low VOC, odorless, REACH/RoHS compliant | ❌ High VOC, strong odor |
| Adhesion | ✅ Bonds to most substrates without primer | ❌ Often requires primers |
| Cost Efficiency | ✅ Long-term savings (less maintenance) | ⚠️ Lower upfront cost, shorter lifespan |
