Composition comprising cyclic secondary amine and methods of coating drinking water pipelines

A pavement marking composition comprises an isocyanate-containing component and an amine-containing component. At least one of the components comprises plasticizer and at least one of the components comprises filler. The composition comprises about 5 wt. % or more plasticizer and is substantially free of polyaspartic ester amines.

Pavement marking compositions

An in-situ applicator for applying a composition in a pipe comprises a flow diverter configured to receive a composition and eject the composition from at least one outlet. The applicator also comprises a hollow conical body having a narrow end, a broad end, and an interior surface configured to receive the composition ejected from the flow diverter. The conical body also has a plurality of holes forming a band that wraps circumferentially around the conical body which defines a flow region on the interior surface between the band and the narrow end. The band includes first holes adjacent to the flow region where each of the first holes has a first average diameter and second holes disposed between the first holes and the broad end, each of the second holes having an average diameter greater than the first diameter.
