High Activity Medium Modulus MS Polymer MS3303M

Manta MS3303M is an alkoxysilane-terminated polyether (STPE, also known as silane-modified polymer, SMP) with a polyoxypropylene backbone. In moisture-curing systems it hydrolyzes and crosslinks with ambient humidity to form a durable elastic network. It cures at room temperature in the presence of catalysts such as amine or tin compounds.

Compared with conventional silicone and polyurethane technologies, MS3303M is solvent-free, suitable for low-VOC formulations and contains no free isocyanates. It offers good adhesion to many substrates without primer, bubble-free curing and a paintable surface. Fields of use include construction, general industry, transportation and new energy, including EV battery and solar module assembly, subject to application testing.

MS3303M has the same listed viscosity (40,000 – 50,000 mPa·s at 25 °C), activity and modulus as Manta MS3303T. The MS3303T data sheet is oriented toward clear sealants, glass assembly and fast production lines, while MS3303M is described for general elastic sealing and bonding. For a lower modulus, see Manta MS3303I (low-to-medium modulus, 35,000 – 45,000 mPa·s at 25 °C).

• Elastic sealants and structural adhesives: base polymer that cures at room temperature with atmospheric moisture in the presence of amine or tin catalysts
• Potting compounds and coatings: base polymer for potting compounds and protective coatings
• Construction, general industry and transportation: one-component (1K) or two-component (2K) products that bond to a wide range of substrates
• New energy: EV battery and solar module assembly, subject to application testing
