  • Polymer composition, method for applying such composition and use of such composition in railway track structures
    Patent number: 8946370
    Abstract: A polymer composition comprises a) a component 1 comprising a silane-terminated prepolymer; and b) a component 2 comprising water; and c) a component 3 comprising a silanol condensation catalyst. The composition is packaged in at least two separate packages prior to application, wherein no package contains all three components 1 and 2 and 3. In the composition water is present in an amount of 0.01 to 10 pbw per 100 pbw of prepolymer present in the composition, and the apparent viscosities of each of the packages is at most 95 Pa·s (Brookfield viscosity (A/6/10)) according to ISO 2555 at 23° C. The composition may suitably applied to railway track structures for the dampening of noise and vibrations of rails.
