Polymer composition, method for applying such composition and use of such composition in railway track structures

Railway track structure, produced by a process comprising:

• i) mixing a polymer composition comprising
• a) a component 1 comprising a silane-terminated prepolymer;
• b) a component 2 comprising water;
• and
• c) a component 3 comprising a silanol condensation catalyst,
• which composition is packaged in at least two separate packages, wherein no package contains all three components 1 and 2 and 3,
• in which composition water is present in an amount of 0.01 to 10 pbw per 100 pbw of prepolymer present in the composition, and
• wherein the apparent viscosity of each of the packages is at most 95 Pa·s (Brookfield viscosity (A/6/10)) according to ISO 2555 at 23° C., to obtain an uncured mixture;
• ii) applying a layer of the uncured mixture to at least one substrate;
• and
• iii) allowing the layer of uncured mixture to cure.
