Method of marking a trafficway surface

摘要

A trafficway surface (e.g. road, taxiway) is marked by applying a polyurethane thereto. The polyurethane may be produced by impingement mixing of two or more polyurethane forming components. One component may be MDI or MDI modified with a glycol or amine and the other component may be a polyol or an alkoxylated polyol. A hydroxy or amine cross-linking agent may be incorporated in one of the components as may a catalyst.
