The Paint and Chemical Industry
The paint and chemical production processes are quite efficient. However ‘quite efficient’ will not be enough in the future. The digital revolution has already transformed many industries, the paint and chemical industry are next.
We can not imagine a world without paint! Paint is much more than just a color in a paint can. Painted objects not only looks better, paint makes objects easier to see.
Painted objects are more interesting than ones without. Paint themselves have become associated with certain feelings and ideas. Paint also helps to protect objects, against scratches, weather etc. In short.. we think our world is nothing without paint.
The human have been painting to memorialize their lives since the Stone Age. Pigments for these paints included blood, juice, dried plants and many minerals. Since Middle Ages the human introduced new materials, colors and technologies.
The first modern synthetic pigment (Prussian blue) was discovered in the early eighteenth century by accident when a chemist was trying to make a different color. By the end of the nineteenth century almost any color could be purchased.

The Chemicals inside Paint
Paint is more than just a chemical dissolved in a liquid. Paint have three main components, pigment, binder (resin) and solvent. Typically there will be a number of additives added to improve the paints properties in various ways, depending on where and how it is going to be used.
The color chemical in paint is pigment. It looks a certain color because it reflects some wavelengths of light and absorbs others. Traditionally metal compounds (salts) are used to create different colors. These different compounds (e.g. titanium dioxide, iron oxide, chromium oxide) create all their own color. Mixing different pigments makes paint of any color you can imagine.
Pigments are typically solids. Without the substance called a binder, the pigment would be difficult to apply. It would not stick to a wall or paper and wash straight off if they got wet. Some binders are made from natural oils but most are made from synthetic plastics nowadays.
Without the third major chemical solvent, is the substance difficult to spread. The solvent is a chemical that dissolves something else. The solvent forces to make the pigment and binder into a thinner and more flowing liquid. Once the paint has spread, the solvents evaporates into the air. Water is the best-known and most versatile solvent. One big advantage of water based paints is, it is relatively easy to clean. Oil based paints use solvents from organic chemicals (extracted from petroleum). Oil-based paint is more durable but it takes longer to dry and clean up requires thinner.
Most paints also contains additives. Ceramic substances can be added to the paint to improve the strength and durability. Additives in paint designed for outdoor use, can help make objects rust- and waterproof, keep them free of fungus and protect against frost or sunlight.
The manufacturing process
There are five critical parts in the production process of paint. Measurement of ingredients, pigment dispersion, mixing, laboratory testing and filling.
The paint components (solvents, binders, additives) are measured and weighed on scales and will be premixed to form a paste (pigments are added next). The mixture paste is now routed into a mill, this process blends the paste into a solvent. The pigment will be added next after it is dispersed. The paste turned into paint and it is ready to be tested in the laboratory. After the paint is approved, it will be filled in cans and labelled. Now the paint is ready for shipping!
In this process there are different machines required to produce paint. In tanks are the paint components stored, these components are made into paint by mixers, mills and dispersing machines. After which the paint is filled in cans by the filling machine, the cans are provided with labels by the labelling machines and are ready fo
The chemical industry is a prime factor to convert raw materials into desired products that we use in our day-to-day life. The chemical industry is very important to us, this industry has touched all our facets of life like food, hygiene, transport, agriculture and the re-cycling industry.
The chemical industry comprises the companies that produce industrial chemicals. The industry had a wide range of all kind of liquids, e.g. solvents, binders/resins, oil. Some chemicals may require special safety measures to guarantee a save (working) place, for example toxics or flammable chemicals can require a venting system.
High productivity, reproducibility and quick product changes are critical in the chemical manufacturing process. Chemical products have to comply with strict environmental regulations and rigorous quality and safety standards. To meet these requirements you depend on aligned processes within your company. CoatSystem provides an efficient and progressive way of working, using our service is not only an advantage for your purchasing process but the rest of your company processes too.
