In our summer educational series on paint and color technology, we begin with a review of one of the basics: what ingredients are in paint? The variety of paint products offered can be overwhelming. And with each variety of paint offering different properties that affect the outcome of a design project, understanding what's in a can of paint is key to success. All paints generally have four main ingredients -- pigments, binders, solvents liquids and additives. Pigments provide color and hide, while binders work to "bind" the pigment together and create the paint film.
What Is Paint Made of?
To improve your ability to pick the right paint for the right space, it helps to understand what goes into the product. Most paints consist of the same basic components: pigments, binders, liquids, and additives. Each component serves a role in determining the quality of the paint as well as its performance both during and after application. Pigments, either organic or inorganic, are what give the paint its color and its ability to cover. PVC, expressed as a percentage, is the ratio of the pigment volume to the total volume of solids in a particular paint.
Paint is used to decorate, protect and prolong the life of natural and synthetic materials, and acts as a barrier against environmental conditions. Paints may be broadly classified into Decorative paints, applied on site to decorate and protect buildings and other objects, and Industrial coatings which are applied in factories to finish manufactured goods such as cars. The binder resin and solvent together are sometimes known as the vehicle. The binder may be dissolved as a solution or carried as a dispersion of microscopically small particles in a liquid. Paints are formulated according to their proposed use - primer, undercoat, special finishes matt, gloss, heat resistance, anti-corrosion, abrasion resistance.
Basic Paint Components and Their Role in Quality, Performance
Paint is any pigmented liquid , liquefiable, or solid mastic composition that, after application to a substrate in a thin layer, converts to a solid film. It is most commonly used to protect, color, or provide texture to objects. Paint can be made or purchased in many colors—and in many different types, such as watercolor or synthetic. Paint is typically stored, sold, and applied as a liquid, but most types dry into a solid. Most paints are either oil-based or water-based and each have distinct characteristics. For one, it is illegal in most municipalities to discard oil based paint down household drains or sewers.
pigment(s) - prime pigments to impart colour and opacity.
What is in a can of paint
Different types and grades of paint provide different application and resistance properties, depending upon the kinds and levels of ingredients used to create the paint. In turn, the properties of a paint determine the general quality of the coating. Pigments are finely ground particles or powders that are dispersed in paints, provide color and hiding; and some are used to impart bulk at relatively low cost. The binder affects application properties like flow, leveling and film build, and gloss development. Pigments and the binder are what are left on a surface when the paint dries and the liquid portion evaporates.
It is a volatile liquid used to obtain desired viscosity and flow of the paint. It keeps the solid components of paint in suspension and also influences the adhesion properties of the surface. It is an optional component of paint i. The solvent after application of paint evaporates to leave a solid dry film on the surface.
Industrial paint, as used to protect metal, wood, and a wide range of other materials, possesses a variety of traits that can be manipulated to provide application-specific coverage. Of course, these characteristics depend in a large part upon the ingredients of the paint and the performance specifications of the selected application. Application methods, too, can influence the quality of the paint coverage and determine how well paint adheres to the substrate. Industrial paints are specially formulated to meet the needs of various industries including aerospace, over-the-road equipment, civil projects, canning, heavy machinery, marine, etc.
General Industrial Paint Components
Paint has to be one of the most common but underappreciated substances ever invented. There is nothing in your life that is not in some way affected by paint. We put paint on our walls, our appliances, and on the hood of our cars, to protect these valuable surfaces. Paint comes in thousands of different types, purposes, and colors, and line distributor shelves by the hundreds. Even chemists and chemical engineers who design and experiment with advanced paint formulas realize paint composition can be extremely complicated. However, the four basic components in a typical can of paint are actually quite straightforward.
