Abstract:
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.
Abstract:
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.

Abstract:
A curable composition includes: a) at least one aliphatic polyisocyanate; b) at least one aliphatic polyamine; and c) from 8 to 17 percent by weight of at least one liquid compound, based on the total weight of components a), b) and c) combined. Each liquid compound is independently represented by the formula (I): wherein Z represents an n valent organic group, and n represents an integer ≧1. Methods of coating the curable coating on a substrate and composite articles are also disclosed.
