Transparent Silane Terminated Polyether MS3303T

Manta MS3303T is an alkoxysilane-terminated polyether (STPE, also known as silane-modified polymer, SMP) with a polyoxypropylene backbone. It is a base polymer for moisture-curing systems and forms an elastic network through hydrolysis and crosslinking of its alkoxysilane groups in ambient humidity, at room temperature and in the presence of catalysts such as amines or organotin compounds.

Compared with conventional silicone and polyurethane technologies, MS3303T is solvent-free, suitable for low-VOC formulations and contains no free isocyanates. It can be formulated as a one-component (1K) system for ease of use or as a two-component (2K) system for deep-section curing.

MS3303T is listed with the same viscosity (40,000 – 50,000 mPa·s at 25 °C), activity and modulus as Manta MS3303M. Its data sheet is oriented toward clear sealants and adhesives and toward production lines requiring fast curing and high initial green strength. For a lower modulus, Manta MS3303I has a low-to-medium modulus at 35,000 – 45,000 mPa·s at 25 °C.

• Clear sealants and adhesives: high transparency and yellowing resistance for glass assembly, decorative bonding and visible joints
• Industrial assembly bonding: production lines requiring fast curing and high initial green strength, in 1K systems for ease of use and 2K systems for deep-section curing
• Electronic potting and encapsulation: can be evaluated for moisture and chemical protection of electronic components; electrical properties and long-term reliability must be verified
• Transportation: bonding and sealing of vehicle components requiring high elasticity and aging resistance
• Construction: elastic sealing of curtain walls, window perimeters and interior decoration with a paintable, solvent-free and low-odor finish
