Abstract
A surface marker resin formulation is provided that includes a linear aromatic polyester or a co-polymer thereof. The resin is dissolved or dispersed in a solvent exclusive of naphtha. An inorganic particulate having an average maximal linear extent of between 10 and 130 microns present from 22 to 41 total weight percent. A process of marking a surface includes two articles being brought into a pre-selected alignment to define a surface. A continuous bead is applied to the surface. The solvent evaporates to a state of dry-to-touch in a time of between less than 60 seconds to mark the surface. The formulation is readily applied from a pen to achieve a controlled bead width. The drying of the formulation by solvent evaporation yields full hardness in 24 hours under standard temperature and pressure as measured at 0% humidity.
