  • Pigments
  • Binder or Vehicle
  • Carrier
    1. PIGMENTS

Pigments are finely grounded powder that are dispersed in paints, providing color and hiding. There are two primary categories of pigments prime and extenders. Prime pigment provide whiteness and color and are the main source of hiding capability. Titanium dioxide (TiO2) is a predominant white pigment, provide exceptional whiteness by scattering light; provides whiteness and hiding in flat and glossy paints. Extender are used to ensure proper spacing of particles to avoid crowding and loss of hiding and provide greater chalking tendency to paints. In contrast color pigments, (either organic or inorganic) provide color by selective absorption of light. Color pigments are compounded into liquid dispersions called colorants. In factories color pigments are use as dry powder and in liquid colorant form to make pre-packed color paint. Commonly use extender are clay, silica, silicate, calcium carbonate, talc and zinc oxide.

    1. Binder

It provide adhesion, integrity and toughness to the dry paints by binding the pigment together. The binder effect properties like flow leveling and gloss development. Oil based binder are generally refer to both oil and alkyd coatings and some coatings particularly exterior primers are made with the combination of both oil and alkyd to achieve appropriate flexibility. The most commonly used binder are cold pressed linseed oil, however, it can be made with walnut oil, poppy seed oil, safflower oil or other less popular oils.

    1. Carrier

The liquid portion of the paint (also referred to as Carrier) provide desired consistency and it possible to apply the pigment and binder to the surface being painted. For most oil based and alkyd paints, the liquid component is paint thinner and water is primarily used in latex paint. When we apply paint to any surface the liquid portion (generally thinner) is evaporate and what remain on the wall is pigment and binder. Together they are called the solid portion of the paint (pigment + binder = solid). While the coating is a combination of liquid and solid.

MANUFACTURING OF PAINTS The manufacturing of paint include following steps

  • Preparing
  • Mixing
  • Grinding
  • Coloring
  • Filtering
  • Packing
    1. PREPARING

The paints are prepare by pigments and fillers, binders (oil or resins), solvent, plasticizers, driers other raw material. In Industries paints are manufacture by using water ring type vacuum pumps to suck the raw material into a chemical reactor which can reduce manual work.

    1. MIXING

Now raw material is put into a high speed dispersing kettle which mix all the raw materials and form mixture and you get a semi-finished paint.

    1. GRINDING

Now semi-finished paint is put into the horizontal sand miller to grind the granule (residue from the semi-finished paint) into smaller particles, for the better stirring.

    1. COLORING

Now after grinding process put the semi-finished paint into the color mixing tank, add some pigment or other additives into it to make other color for the paint. If the paint need to be diluted, it can be finished in this tank.

    1. FILTERING

After all these process of mixing, grinding, coloring it is essential to filter it to remove all impurities from the paint to obtain high-quality paint.
