In construction and industrial projects, project delays, leaks, and rework can quickly escalate costs. MS polymer sealants offer a reliable solution. Learn about the advantages of MS polymer sealants and how to apply them correctly.
1)What is Hybrid Polymer Sealant?
Modified silane (MS) polymer sealants are silane-terminated polymers that cure through a moisture-initiated reaction. Unlike solvent-based products, modified silane sealants are typically isocyanate-free, solvent-free, and have low VOC content, making them more environmentally friendly.
2)Key Performance Advantages of MS Hybrid Sealant
1. Strong Adhesion to a Variety of Substrates
Hybrid polymer sealant exhibit excellent adhesion to a wide range of substrates, including metals, glass, wood, and ceramics, often requiring no primer.
2. Excellent Displacement Capacity
They possess excellent displacement properties, absorbing expansion and contraction stresses in construction joints while maintaining tensile strength.
3. Paintable
4. Weather-resistant and UV-resistant
They resist cracking, shrinkage, and yellowing under UV exposure, ensuring durability for outdoor applications.
5. More environmentally friendly
MS polymer sealants have low volatile organic compound (VOC) content and are free of isocyanates or solvents.
3)Limitations to consider
While modified silane sealants excel in many areas, it’s important to understand their limitations:
1.Heat resistance is not as good as pure silicone
Conventional silicone sealants still outperform pure silicone sealants at high temperatures.
2.Cost factors
MS polymer sealants may have a slightly higher upfront cost, but offer a longer service life.
4)Best applications for Hybrid Polymer Sealant
Interior decoration
Floor installation
Building exterior sealing
Mixed polymer (MS) sealants offer multi-surface adhesion, weather resistance, paintability, and durability—while being safer and more environmentally friendly. Tengyu Chemicals has extensive experience in sealant technical support and can help you choose the most suitable MS polymer sealant.
