An electrostatic rotating bell atomizer was used to produce a spray of a 20 wt% aqueous glycerol solution. Droplet size distributions were measured by photographing droplets in-flight and using image analysis software to measure their diameters.
In the present research article, a hyperbranched alkyd resin was synthesized by using bio-based material (castor oil based fatty amide) and pyromellitic dianhydride. The synthesized hyperbranched alkyd resin was characterized by nuclear magnetic …
Three urethane methacrylates, one monofunctional derivative and two di-functional derivatives with different chain lengths were used as reactive diluents in UV-curable polyester powder coatings. Each reactive diluent was formulated with a …

To shed light on the self-stratification mechanism in epoxy–acrylic coatings, 200-, 400-, and 800-micron-thick coatings were applied on glass and aluminum substrates, and their solidification behavior was studied. Some of the applied coats showed …
Poly(o-bromophenol-co-N-methylaniline) [poly(OBP-co-NMA)] was electropolymerized in an acidic medium at 30°C under inert atmosphere. The formed polymer was characterized using IR spectroscopy, XRD, SEM and TGA analysis. The efficiency of the …
