The composition includes a polymeric resin having at least one ,-unsaturated ester group, a vinyl aromatic compound having at least one vinyl substituent on an aromatic ring, and an amino- or mercapto-substituted compound represented by formula (HD).sub.1-4-R. Each D is independently S or N(H) and R is a monovalent alkyl, alkenyl, or polyalkyleneoxy or a multivalent alkylene, alkenylene, or polyalkyleneoxy, wherein the alkyl, alkenyl, alkylene, or alkenylene are each interrupted by at least two O, N(H), N(H)C(O), SC(O), or OC(O) groups or a combination thereof. A method of repairing a damaged surface using the composition is also described.

A composition, device, and method for maintenance of railroad wood ties is presented herein. The device comprises a system for simultaneously filling rail spike holes in wood cross ties including a controlled system able to move in the x, y, and z planes. The system includes a product distribution box with multiple valves and dispensing lines for applying an environmentally friendly wood filler composition into multiple rail spike holes simultaneously. The wood filler composition is applicable for filling holes or gaps in wood to stabilize wood structures.

Described is a method for the production of a moisture curable composition whereby the reactive end groups of a reactive polymer are reacted with a cross-linking agent for forming a prepolymer, whereby the method is operated in batch mode and the production of the prepolymer occurs in a mixing vessel, characterized in that the reactive polymer and the cross-linking agent, as well as the additional ingredients necessary for the production step in the mixing vessel, are introduced into the closed mixing vessel and react without opening the mixing vessel, and the mixing takes place without opening the mixing vessel, and the product is removed from the mixing vessel without opening the mixing vessel.
