MS polymer is a kind of cross-linked polymer based on silane-terminated polyether. MS polymer products do not contain silicone components and solvents, do not contain polyurethane groups, most formulations are odorless and environmentally friendly, MS adhesives and sealants inherent elasticity, can absorb and compensate for dynamic load, uniform transfer force, prevent premature fatigue of materials, MS materials can achieve a variety of substrate bonding.
Peculiarity
Typically without surface treatment, such as a primer, MS polymers are cross-linked or cured by continuous exposure to moisture. The moisture mainly comes from the air or the bonded substrate itself. SPUR stands for silane-terminated polyurethane similar to MS polymer, and STP stands for silane-terminated polyether (STP) similar to MS polymer containing polyurethane groups. In essence, MS, SPUR and STP are three different polymers.
