Abstract:
Abstract Polyvinyl acetate (PVA) polymer resins are commonly used in the manufacture of artisanal paints with natural inputs, giving them the classification of economic latex paint according to NBR 11702. Aiming to minimize the final cost, since PVA is the most expensive component, this study contributes to the area of building paints through the innovative idea of formulating paints with PVA resin, curcumin pigment extracted from the root of Curcuma Longa L., color preservative additives and bacterides, in order to find the appropriate proportions capable of reaching the minimum limit of resi

Abstract In this paper, a specific emulsion polymerization of acrylic monomers, in the presence of silica particles, is developed to improve the physical properties of the base polymers and add proper functions to them. With this technique, nanocomposites were made by using two types of nonionic and anionic surfactants. To apply resins as water-based paints, the properties of two nanocomposite latexes were measured and the results were reported. The basic properties of nanocomposite acrylic paints, adhesion, surface hardness, wet scrub, scratch, flammability, gloss and solvent resistance, were

Abstract The requirements put on coating materials are more and more stringent mainly in the environmental domain, especially as regards VOC emissions.

The latexes were synthesized via two--step emulsion polymerisation to obtain a core-shell system. Nanostructural ZnO in an amount of 1.5 wt. % wa

Emulsion stabilization by native cellulose has been mainly hampered because of its insolubility in water. Chemical modification is normally needed to obtain water-soluble cellulose derivatives. These modified celluloses have been widely used for a range of applications by the food, cosmetic, pharmaceutic, paint and construction industries. In most cases, the modified celluloses are used as rheology modifiers (thickeners) or as emulsifying agents. In the last decade, the structural features of cellulose have been revisited, with particular focus on its structural anisotropy (amphiphilicity) and
