MS Polymer Type STPE
MS Polymer for Flooring Adhesives | Manta MS2628
Manta MS2628 is a low-viscosity silyl-terminated polyether (STPE) with high modulus, used as a binder for moisture-curing flooring adhesives, industrial adhesives and general-purpose adhesives. It is suitable for hot and cold blending, allows high filler loadings while maintaining processability, and can be formulated solvent-free and isocyanate-free.

- Silyl-terminated polyether (STPE)
- Form
- Light yellow viscous liquid
Overview
Manta MS2628 is a low-viscosity silyl-terminated polyether with moisture-reactive silyl functional groups for moisture-curing adhesives and sealants. It is designed for a balance of fast reactivity, high hardness and storage stability.
MS2628 is suitable for hot and cold blending and allows high filler loadings while maintaining processability. It gives a short tack-free time and develops a high modulus shortly after application. Its silane end groups hydrolyze on contact with water or atmospheric moisture, release methanol and condense to form a siloxane network. Formulations based on MS2628 can be solvent-free and isocyanate-free.
MS2628 and Manta MS7500 are both high-modulus grades. MS2628 has the lower viscosity, 6,000 – 9,000 mPa·s at 25 °C compared with 40,000 – 60,000 mPa·s at 25 °C, and is listed for flooring, industrial and general-purpose adhesives, while MS7500 is designed as a binder for semi-structural adhesives and high-strength sealants.

Applications
- Flooring adhesives: moisture-curing formulations with high filler loadings
- Industrial adhesives: high-modulus bonding with a short tack-free time
- General-purpose adhesives: solvent-free and isocyanate-free moisture-curing formulations
Processing
The silane end groups of Manta MS2628 hydrolyze on contact with water or atmospheric moisture, releasing methanol, and condense to form a siloxane network. Store and process the polymer with moisture excluded.
Dry fillers and pigments before use. Vinyltrimethoxysilane (VTMO) is commonly used as a water scavenger to improve the storage stability of the formulated product.
Fillers, plasticizers, catalysts and additives commonly used in silane-terminated polymer formulations can be used; their type and level should be confirmed by testing in the specific formulation.
