Contact: Dr. Charles F. Palmer Ethox Chemicals [email protected] T +1 864 277 1620 They are used in many industrial and architectural applications. The hydrophobic nature of the alkyd polymer makes them good choices when water repellency is important. However, formulating alkyds into low VOC (volatile organic compound) waterborne coatings results in a number of problems, which can be minimised ...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
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 ...
Alkyd resin merupakan produk polimer yang banyak digunakan dalam industri cat, coating, dan pembuatan film. Hal ini dikarenakan keunggulan sifat – sifatnya sebagai surface coating meliputi fleksibilitas, kekuatan durabilitas, serta adhesi baik. Penelitian membuat alkyd berbasis palm fatty acid distillate (PFAD) urea formaldehide terbutilasi dengan variasi rasio molar butanol 0,5-3 mgrek/mgrek. ...
