The examination of polymer material by transmission electron microscopy (TEM) often relies on staining in order to improve contrast or preferentially stain a polymer phase. Stains such as osmium tetroxide for unsaturated polymers and ruthenium tetroxide for unsaturated as well as certain saturated polymers have been used quite extensively. A new stain, 3-iodopropionic acid, has been found to be very useful to stain preferentially the amine rich domains in waterborne epoxy films.An epoxy dispersion (epoxy equivalent weight, EEW=625) and a polyamine adduct curing agent (AHEW=163) at a 1.5:1 stoichiometry was prepared. The volatile organic content (VOC) was 2.6 lb./gal., and the solvent blend was 90.6% propoxy ethanol and 9.4% Aromatic 150. The particles size of the starting dispersion was obtained by TEM and disk centrifuge and found to be approximately 500 nm. Films (approximately 1.2 mil dry film thickness[DFT]) were cast on a partially fluorinated polyethylene film, 0.5, 2, 4, and 8 hours after hand mixing and cured for two or more weeks at 25° C and 50% relative humidity.

This paper explains the advantages and shortcomings of waterborne marking paint, based on technical characteristics thereof, describes the physical and chemical properties of said paint required in China, discusses the application status of said paint in China and abroad, and proposes the application trend of said paint in China. The results showed that: the waterborne marking paint has little damages on human and environment because of less volatile organic content (VOC), and has many other advantages such as good retroreflective performance, more conveniently cleaning effect for applying equipment and good skid resistance, etc., while it has the shortcomings of thermal sensitivity, easily freezing performance and metal corrosion, for example; the waterborne marking paint has been used with the third amount based on the total of road marking paint in China, but a further progress needs to be made for the waterborne marking paint in technology, application and market promotion in order to improve its field of application.
