Origin and characteristics of coatings

Paint is a kind of paint made of iron oxide or resin, which is used to decorate and protect objects. This paper will introduce the origin and material characteristics of coatings to help readers better understand coatings.

Uncertain origin

The origin of paint is still inconclusive. In 6000 BC, China improved the paint by mixing and baking inorganic compounds and organic pigments. In BC 1500, in caves in France and Spain, paint was used for painting and decoration.

Natural substances and chemical products

Traditional coating products based on natural substances and modern developing coating products based on synthetic chemical products belong to organic chemical polymer materials, and the formed coating films belong to polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products.

tinder

This kind of paint is a viscous oily pigment, which is flammable under wet conditions.

Insoluble in water

Paint is insoluble in water, slightly soluble in fat, soluble in alcohol, aldehyde, ether, benzene and alkane, soluble in gasoline, kerosene and diesel oil.

Multifunctional engineering materials

Modern coatings are gradually becoming a multifunctional engineering material and an important industry in the chemical industry.
