INGADA™ MS-625 Low-Modulus Polyether Sealant – Silane-Modified Polymer
±25% Movement Capacity for Prefabricated Construction
-
Stop Joint Cracking: Standard sealants fail under structural expansion; MS-625 “breathes” with your building.
-
Protect Fragile Substrates: The ultra-low modulus design ensures the sealant stretches before the substrate breaks.
-
Sustainable Building Choice: Ideal for Green Building projects requiring zero-solvent, eco-certified materials.

Q：What is the movement rating for MS-625?
A：MS-625 provides a 25-grade movement capability (±25%), suitable for expansion joints in infrastructure and curtain wall sealing.
Q：Can MS-625 be applied in cold weather conditions?
A：The recommended application temperature is between 0℃ and 40℃. In cold climates, it is advised to pre-warm the material before use.
Q：Does MS-625 require a specific surface moisture level?
A：Yes, for optimal adhesion, the substrate should be clean and dry, with a moisture content of ≤8%.
Q：Is this sealant compatible with painted surfaces?
A：Yes, MS-625 is compatible with painted surfaces, concrete, metal, and most other common construction materials.
Q：How durable is MS-625 against fatigue?
A：Its durability is verified through 5000 fatigue cycles, ensuring long-term reliability in dynamic structural environments.
