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 ...

Aims: An eco-friendly coating emulsion prepared with mixture of oils sesame and grape seed alkyd-based waterborne varnish. The applied four different wood substrates (walnut, beech, cedar fir) in order to be investigated for some selected surface properties.
 Study Design: Several test methods were used evaluate physicochemical properties the coatings. results obtained may suggested select...

For a purified preparation of the soluble form of phosphatidate phosphohydrolase (EC 3.1.3.4) from guinea pig cerebral cortex, I-O-alkyl-racglycerol 3-phosphate was found to be accepted as a substrate. This substrate analog was tritium-labeled in order to serve in a rapid sensitive assay for the enzyme, in which labeled I-alkyl glycerol is released. Heat denaturation and enzyme activity depende...

Benzoguanamine (2,4-diamino-6-phenyl-1,3,5-triazine) is used to increase thermoset properties of alkyd, acrylic and formaldehyde resins. It is used as a raw material for guanamine resins. Maleic acid is used as an oil and fat preservative and food acidulant. Crystal structures of melaminium (2,4,6-triamino-1,3,5-triazin-1-ium) maleate monohydrate 201 and Bis(melaminium) DL-malate tetrahydrate 2...

Epoxidized oils, manufactured by chemical epoxidation of fats and vegetable oils such as soybean [Glycine max (L.) Merr.], are useful in reformulation of oil based (alkyd-resin) paints to reduce emissions of volatile organic compounds that contribute to production of smog. Other potential markets for epoxy fatty acids include plasticizers, additives to polyvinyl chloride, polymer blends and coa...
