Spray paint works the way it does because it’s actually a combination of paint and a gas propellant. During the manufacturing process, the cans are first filled with paint and then injected with the gas propellant. The valve is then crimped, trapping the highly compressed compound within the confines of the can.
What are the ingredients in spray paint?
Each type of paint contains four main ingredients, which are solvent, binder, pigment and additives. The solvent is added to the paint as a liquid used to carry the components of the paint from its container, in aerosols the solvent is used to maintain the consistency of the paint as it is sprayed from the can.
How do you manufacture aerosol spray paint?
1 The first step in manufacturing aerosol spray paint is to prepare the liquid concentrate in large metal or glass tanks. This process involves mixing the liquid ingredients such as solvents, corrosion inhibitors, and pH and viscosity control agents with large impeller type mixers driven by electric motors.
What solvent is used in spray paint?
The solvents commonly used in solvent-based aerosol paints for solubilization of the paint resins are aromatic compounds such as toluene or xylene, various ethylene glycol ethers and methylene chloride. These compounds are good solvents and produce excellent solvent-based aerosol paints.
Does spray paint contain metal?
Most aerosol paints also have a metal, marble, glass or plastic ball called a pea inside of the can, which is used to mix the paint when the can is shaken.
Can you make your own spray paint?
Using the spray mechanism found in standard spray cans and some common discarded items you can make your own spray paint.

What is acrylic spray paint made of?
Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion and plasticizers, silicone oils, defoamers, stabilizers, or metal soaps. Most acrylic paints are water-based, but become water-resistant when dry.
Is spray paint acrylic?
Acrylic: Acrylic spray paint is a water-resistant and flexible substance that provides a durable finish, and is often used in automotive paints. Oil-based: Oil-based spray paints don’t usually need a primer, and are highly resistant to chipping and corrosion.

How is paint made using chemistry?
Paints contain: pigment(s) – prime pigments to impart colour and opacity. binder (resin) – a polymer, often referred to as resin, forming a matrix to hold the pigment in place. extender – larger pigment particles added to improve adhesion, strengthen the film and save binder.
