Alpha Silane-Terminated Polymer | Manta MS310A

Manta MS310A is a silane-terminated polyether with highly reactive silane end groups on a polypropylene oxide (PPO) backbone. It cures rapidly on exposure to atmospheric moisture to a stable siloxane network.

It is intended for formulators who need a fast-curing binder for adhesives and sealants that can be formulated without organotin catalysts, including tin-free and phthalate-free systems. The low viscosity allows easy compounding with conventional fillers and additives and high filler loadings, while the low glass transition temperature (Tg) of the polyether backbone helps the cured material remain flexible over a wide temperature range.

MS310A and Manta MS313 are both high-activity polymers that allow tin-free formulations. MS310A has the lower viscosity of the two: 8,000 – 12,000 mPa·s at 25 °C compared with 30,000 – 42,000 mPa·s at 25 °C.

• Sealants: construction and industrial sealants requiring fast curing and paintability
• Elastic adhesives: binder for elastic assembly adhesives in automotive, rail vehicle and structural engineering applications
• Flooring adhesives: parquet and wood flooring adhesives; high filler loadings are possible
• Potting and encapsulation: can be evaluated for protecting electronic components; electrical and long-term properties must be verified in the final formulation
• Coatings: reactive binder or additive to improve adhesion and crosslink density
• DIY and professional bonding: adheres without primer to many substrates, including metals, plastics and ceramics; adhesion should be confirmed on the actual substrate
