How is paint made?


Paint can often seem like a magical blend of colour and strange smells. Whether you are into arts and crafts or are interested in revamping the walls of your home, you may wonder just how paint is made. Paint is not naturally occurring in nature and based on the type of paint that is used, has different processes for its creation.


Creating Colour: Pigments, Solvents, Additives


All paint is created using pigment, solvent, resin and additives. The pigment in paint is what gives the substance colour. Pigments are divided into two groups. One, the "Prime Pigments", and the other, the "Extender Pigments". "Prime Pigments" include Titanium Dioxide or White, Yellow Iron Oxide, Red Iron Oxide, and Chrome Green Oxide. The "Extender Pigments" include Calcite or Calcium Carbonate, Talc or Magnesium Silicate, Mica, Barytes or Barium Sulphate and more.


Binding

 

The resin in pain is the binder that holds the pigments together and gives the paint the adhesion it needs to stay on the surface when applied. Water based paints must use acrylic emulsion polymers as binders. The most common types of acrylic polymers include butyl methacrylate, methyl methacrylate, and poly vinyl acetate or PVA binders.

 

Solvent based resins are also called alkyd resins and are typically used to bind enamel paint. These alkyd resins can be found in most varnishes and coating like Urethane, Moisture Curated Urethane, Epoxy and Polysiloxane.

 

Solvents and Additives

The solvent in paint is used as a carrier with the resin and pigments. Many solvents are organic like water or Mineral Turps. Additives in paint are used to enhance specific properties in the paint. These types of additives can aid in brushing, dirt resistance, efficient drying and more.

 

Manufacturing and Production

 

Most paint is mass produced within factories. When batches of paint are produced, machines carefully go through a process to ensure that each colour is made correctly. The machines carefully and accurately measure variousĀ  ingredients of the pigment, resin, solvent and additives to get the perfect batch of paint. Pigments typically are made in powders that can easily clump together during the production process. The machines must break down these particles with resin and additives, preventing the pigments from being stuck together in the finished product.

 

When you purchase paint at the store, you get a container of what seems to be a pure, perfectly mixed batch of paint. Now that you know all of the time and effort that goes into creating paint, you may enjoy your next home renovation project even more.
