The type of pigment used in paint and coating

There are two main types of pigments: organic and inorganic. Organic pigments are based on carbon and sometimes contain inorganic components. Organic pigments contain carbon components, such as red pigments 202. Inorganic pigments can be blurry, transparent, or transparent. In general, organic pigments are safer to use than inorganic. Below are some examples of organic and inorganic pigments.

Complex Inorganic pigments have improved nature and performance, such as high thermal opacity and UV, hiding power, and infrared reflectivity. While color is the most important consideration when choosing pigments, physical and spectral properties are as important when formulating exterior durable coatings. When choosing a pigment for this application, heat and chemical stability must be considered. UV opacity and hiding power are important attributes for uppermate coatings. In addition, inorganic pigments are non-migration, meaning they will not dissolve or change colors when in contact with solvents.

Earth pigment has been used for thousands of years. They are used by early hunters for cave paintings. Then, they are used to paint buildings and houses. Apart from its weaknesses, the earth pigment has a very low toxicity. Thus, they are used on the early days of painting and put in the artist palette. However, some modern pigments can be corrosive to the surface.

Cadmium -based pigments cause a number of environmental and health hazards. Cadmium is a very poisonous heavy metal. While yellow originating from cadmium is generally insoluble, they still cause problems in solid waste. For this reason, many industries have switched to organic yellow pigments that are less dangerous. After the environmental benefits and the safety risks of cadmium pigment are fully understood, it is important to choose the right color.

The use of natural pigments in paint and coating has increased dramatically during the last century. Organic pigment, conversely, is more expensive and has a lower cover power. Monoazo pigment shows a variety of reddish yellow colors and is very durable. Copper Phthalocyanine Blue (CPB) is another natural pigment used for coloring. Hot stability and good weather also make it a good choice for housepaints. This is also sold as a curiosity blue water paint by Daniel Smith.
