Paint IngredientBefore making anything we need to know about the ingredient used. Some of the ingredients used in the paintings are: Say no to plagiarism.

There are two main categories of primary and extension pigments. Primary pigments provide whiteness and color and are the primary source of masking ability. Titanium dioxide (TiO2) is a predominant white pigment, providing exceptional whiteness by diffusing light; provides whiteness and concealment in matte and glossy paints. Extenders are used to ensure proper particle spacing to avoid crowding and loss of masking and provide a greater tendency for paints to chalk. In contrast, color pigments (organic or inorganic) provide color by selective absorption of light. Color pigments are mixed with liquid dispersions called dyes. In factories, color pigments are used in dry powder and liquid dye form to make prepackaged colored paints. Commonly used extensions are clay, silica, silicate, calcium carbonate, talc and zinc oxide. BinderIt ensures the adhesion, integrity and tenacity of dry paints by binding the pigments together. Properties of the bonding effect such as flow equalization and gloss development. Oil-based binders generally refer to both oil and alkyd coatings and some coatings, particularly exterior primers, are made with a combination of oil and alkyd to achieve flexibility appropriate. The most commonly used binder is cold-pressed flaxseed oil, however, it can be made with walnut oil, poppy seed oil, safflower oil, or other less popular oils . CarrierThe liquid part of the paint (also called Carrier) provides the desired consistency and texture. it is possible to apply the pigment and the binder to the surface to be painted. For most oil and alkyd paints, the liquid component is paint thinner and water is primarily used in latex paint. When we apply paint to any surface, the liquid part (usually thinner) evaporates and what remains on the wall are pigments and binders. Together they are called the solid part of the paint (pigment + binder = solid). While coating is a combination of liquid and solid.PAINT MANUFACTURINGPaint manufacturing involves the following stepsPreparationMixingGrindingColoringFiltrationPackagingPREPARATIONPaints are prepared from pigments and fillers, binders (oil or resins), solvents, plasticizers, driers and other raw materials. In industries, paints are manufactured using water ring type vacuum pumps to draw raw material into a chemical reactor, which can reduce manual labor. MIXINGNow the raw material is placed in a high speed dispersing kettle which mixes all the raw materials and forms a mixture and you get a semi-finished paint.GRINDINGNow the semi-finished paint is placed in the horizontal sand mill for grind the granules (residue of semi-finished paint) into smaller particles, for better stirring.COLORINGNow, after the grinding process, put the paint..
