This work studied the application of phosphoric acid-gallic acid in vinyl chloride acrylic emulsion and its rust conversion performance. The increase affected stability system, leading to rapid precipitation flocculent precipitation. Rust coating (RCC) showed best synergistic effect when gallic (GA) was 0.2 wt.% (PA) 2 wt.%. XRD FTIR analysis show that components adherent (AR) are α-FeOOH, γ-Fe...

The modified waterborne acrylic resin was synthesized successfully by emulsion polymerization with octafluoropentyl methacrylate and phosphate functional monomer as monomers, showing an improved anti-corrosion performance of the coating. existence general distribution elements in were explored, mechanism disclosed. results show that modification monomers water resistance, corrosion resistance t...

Paints are used to protect and prolong the life of natural synthetic materials as it acts a barrier against environmental conditions. contain extenders, solvents, pigments, binders, some additives. The objective is improve physical properties current matt paint formulation. contents acrylic white emulsion known be 25%Pigments, 12% Extender 5% Additives, 44% Solvents, 14% Binders. [2]. Binders m...

The emulsion polymerization of styrene was investigated using polystyrene-b-[polystyrene-r-poly(methacrylic acid)] amphiphilic block-random copolymers (BRCs) different compositions as stabilizers. These stabilizers with molar masses <20,000 g/mol, which possess unique dispersion behaviour (i.e., self-assembly low aggregation numbers) when dissolved in aqueous medium at alkaline pH, were prepare...

The success in the preparation of Eudragit RS100 microspheres in 0.IN HCI solution using gelatin as antiaggregating agent, encouraged the selection of an acidic drug to be encapsulated using a solvent evaporation technique [1]. Ibuprofen is a non-steroidal, anti-inflammatory, analgesic and antipyretic drug approved for use as adjunct therapy in the treatment of rheumatoid and osteoarthritis [2]...

Alkyd resins are amongst the most important and widely used resins in coating sectors. In this communication we report on preparation of alkyd resins emulsified by grafted acrylic resins on their fatty acid moieties. Both high-shear mechanical homogenizer and ultra-sonic sonicator were used step-wise to disperse the alkyd resin and acrylic based monomers in aqueous media. The resins are of nano...

The effects of water/oil volume ratio, type and concentration of demulsifier, water salinity and mixing speed on the average water droplets size in water-oil emulsion are evaluated at different times through NMR measurements.The type and concentration of demulsifier have the greatest effects on the average droplet size with 38% and 31.5%, respectively. The water/oil volume ratio, water salinity...
