In addition to painting houses, protective coatings are wont to give color to automobiles, underground storage vessels, road markings, ships, and lots of more items.
The element in paints that's liable for lending color to many applications is pigmented. Pigments hold an area of great importance within the paint industry with huge quantities of several varieties getting used for various purposes. Pigments in paints act as colorants in commercial, industrial, and ornamental applications. The various sorts of pigments for paints are often listed as below:
Earth Colour Pigments: These are obtained from natural sources and are classified as inorganic pigments. They’re weather-resistant, lightfast, and chemical fast.
The pigment in paints not only acts as a colorant but also offers the underneath surface protection from weathering and corrosion. It’s actually liable for holding the paint together. Mineral Pigments: These are classified as synthetic inorganic pigments. a couple of the pigments included during this category are Chrome oxide green, titanium oxide, Ultramarine sort of pigment blue, Iron oxide yellow, Nickel titanium yellow, etc.
Special pigments are utilized in specific applications like providing metallic finishes to automobile bodies or offering long-lasting features for road markings. Additionally to pigments, paints contain binders and solvents during paint manufacturing.
The binder helps in holding the coating of paint to the substrate. Solvents also called as thinners act as a medium during which the binder, additives and pigments are dispersed as true solutions or as colloidal dispersion.
With industrial applications of paints starting from aerospace, coil, automotive to architectural and ornamental, paint formulations need to fulfill varied technical criteria besides offering durability, opacity, and simple application.
The pigment, binder, and therefore the solvent need to be mixed within the right proportions in order that the ultimately finished output may be a smooth, continuous and attractive coat of paint. The paint technologist and therefore the paint technician adds conjunction to realize the specified final product.
It’s the work of the paint technologist to formulate the paint as per pre-determined standards and therefore the paint technician who is liable for its manufacture to make sure the achievement of the features set down by the paint technologist.
