Which Pigments Can Be Used In Coatings?

Pigment Manufacturing Process

The Pigment Green 7 manufacturing process very involved. First, the raw materials must be selected. Second, the raw materials crushed and milled into a fine powder. Third, the pigment screened to remove impurities. Fourth, the pigment tested for colorfastness. Fifth, the pigment is dispersed in a vehicle. Sixth, the pigment is ground to achieve the desired particle size. Seventh, the pigment is tested again for colorfastness and compatibility with other ingredients.

Eighth, the pigment is dried and heated. Ninth, it is combined with binders and solvents to create a paint or coating. Tenth, sometimes it needs to undergo additional grinding or screening steps if not enough pigment was produced during the production of paint or coating due to the requirements of their applications. Eleventh, some pigments are also treated before they are packaged by adding drying agents that help keep them from clumping together after production

The most common type of pigment found in paints and coatings has been manufactured for many years and consists of titanium dioxide coated with iron oxide (invented in 1865). Titanium dioxide gives off a bright white light when exposed to sunlight while iron oxide provides it with its red-orange hue

Types Of Pigments Used In Coatings

Inorganic pigments are made up of minerals that processed and ground into a fine powder. These include white pigments like titanium dioxide and zinc oxide, as well as color plastic pigments like iron oxide and carbon black. Organic pigments are made from molecules that contain carbon. They tend to be brighter and more vibrant than inorganic pigments, but they also fade more quickly. Some common organic pigments used in coatings are azo compounds, phthalocyanines, and quinacridones.

UV Cure Vs Heat Cured Coatings

Ultraviolet (UV) light cure and heat cure are two methods of curing or cross-linking polymer coatings. Pigment manufacturers in Gujarat offer a variety of products that used in either type of coating. Here is a comparison of the two curing methods to help you decide which is best for your project. – UV Cure: Coatings cured with UV light produce minimal odor, contain no solvents, and require less equipment.

The primary benefit of UV curing is speed – cures usually take 1-3 minutes as opposed to 10+ minutes with heat-cured coatings. On the downside, it’s important to note that UV curing doesn’t work on wet surfaces, so there’s a waiting period between coats before using UV light again. – Heat Cure: Coatings cured with heat require more equipment than UV cured systems but are cheaper to use in general because they only require electricity as opposed to expensive ultraviolet lamps needed for the other process.

The Importance Of UVA Protection

Coatings are one of the most important ways to protect against ultraviolet (UV) radiation. UV radiation is invisible to the human eye but can damage skin, eyes, and immune systems. It is important to select a coating that has the right pigment for the job. Some pigments reflect UV radiation while others absorb it. Pigment manufacturers in Gujarat offer a wide variety of UV-protective pigments. These include special titanium dioxide additives that provide UVA protection, zinc oxide or zinc sulfide additives that provide UVA protection as well as UVB protection, and mica or talc additives which provide an all-around reflection of both UVA and UVB radiation. Different markets will require different types of protective coats depending on their needs.

For example, it’s especially important to use a coating with titanium dioxide if the product expose to high temperatures, such as oven ranges. A good coating provider should also know any potential fire hazards to choose an appropriate fire retardant additive. Manufacturers will also need a high quality primer before they apply any topcoat products with pigments added. Primers allow better adhesion of topcoats and enhance gloss properties on surfaces like plastic or metal. The best primer available water-based for safety reasons and produce minimal odor during application so that there’s no danger of overexposure when handling materials without adequate ventilation equipment at hand.
