- Solvent or Thinner.
- Drier.
- Colouring Pigments or Extenders.
Which oil is used in paints and varnishes?
Linseed Oil
Linseed oils are drying oils commonly having excellent drying characteristics suitable for manufacturing of paints and varnishes, wood preservative and as an agent to protect iron from rust.

What are the properties of paints?
Properties of an ideal paint
- ease of application.
- good flow out of application marks (e.g. brush-marking)
- forming a continuous protective film.
- high opacity.
- quick drying.
- corrosion resistance.
- water resistance.
- heat resistance.
What is the properties of paint?
The constituents of paint 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.
What are the three basic ingredients of paint?
Paint is a science of ratio. At the core paint involves three components: solvent, pigment and resin.

- Pigment impacts the concentration of the paint.
- Resin/Latex/Binder are the variables that give each paint its unique properties.
