The lifespan of organic coatings is reduced in outdoor applications by attacks of solar radiation, oxygen and atmospheric pollutants. Degradation of coating and recoating introduce pollutants into the environment. For solvent base coatings like alkyd paints volatile organic compounds (VOC) are main source of pollution. Undesirable mechanical, physical and chemical consequences of the resulting ...

In this study, different coatings (gray epoxy primer, white varnish and red alkyd paint) of 7075 aluminum alloy are cleaned with a 500 W continuous-wave (CW) fiber laser. We analyzed the influence laser power density on temperature evolution target surface morphology. Under condition continuous irradiation for 1 s, experimental results indicated that suitable cleaning thresholds primer varnish,...

The material composition of a group Rodovetri, hand-painted animation cels, made in the 1950s and 1960s for Italian television, has been determined by Flash Py-GC-MS, Thermally assisted Hydrolysis Methylation-(Py-)GC-MS GC-MS investigations, where, pyrolysis applications, pyrolyzer is connected septum-less to GC inlet. condition selected cels was generally poor (yellowing, exudation, warping, c...

Purpose: Alkyd resins constitute a very high proportion of conventional binders used in surface coatings. In order to enhance the quality of these alkyd resins methyl esters of rubber seed oil (MERSO) were used in the preparation of the resins. Methods: MERSO were obtained by in-situ alcoholysis of rubber seed. Alkyd resins having oil lengths of 45, 50 and 55% were prepared with MERSO, phthalic...

Abstract The present study focuses on the Preparation of Aluminum Oxide, and Copper oxide antifouling coatings to prevent or reduce corrosion fouling in ships marine vehicles. Al 2 O 3 CuO nanoparticles were prepared using ball milling process. nano paints these as pigment linseed alkyd resin a binder. Mild-steel specimens coated with paint immersed seawater for 120 days properties studied Scan...
