The MS polymer is a silane-terminated polyether-based cross-linked polymer. MS polymer-based products contain no silicone components and solvents, no polyurethane groups, most formulas are odorless and environmentally friendly, MS adhesives sealants are inherently elastic, they can absorb and compensate dynamic loads, uniformly transmit stress, and prevent materials from passing Early fatigue, MS-based materials can achieve a variety of substrate bonding.

The typical feature is that without surface treatment, such as a primer, the MS polymer is cross-linked or cured by continuous exposure to moisture. Moisture mainly comes from the air or the substrate itself.
