The document discusses the history and components of paint. Paint is made up of pigments, resins, fillers, solvents, and additives that are mixed together. The manufacturing process involves raw materials being mixed and milled, then blended, filtered, and packed. LabVIEW was used to simulate and monitor the paint manufacturing process. An ideal paint has properties like easy application, hiding power, quick drying time, and resistance to factors like corrosion and abrasion.

4. The surface-coating industry is indeed an ancient one, the origin of paints
dates back to prehistoric times when the inhabitants of the earth recorded some of
their activities in colors on the walls of their caves. These crude paints consisted
probably of colored earths or clays suspended in water. The Egyptians, starting
very early, developed the art of painting and by 1500 B.C. had a wide number and
variety of colors.
Around 1000 D.C. they discovered the forerunner of our present-day varnishes,
using naturally occurring resins or beeswax for their film forming ingredient.
Pliny outlined the manufacture of white lead from lead and vinegar, and it is
probable that this ancient procedure resembles the old Dutch process. It is in more
recent years, however, that the surface-coating industry has made its greatest
strides owing to the results of scientific research and application of modern
engineering

5. 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.

6. Paints contain:
 pigment(s)
 Fillers
 extender
 solvent
 additives
 Binders (Resigns)

7. Paint is one major segment of the surface
coatings, which also includes varnishes, enamels,
printing inks and polishes.
• The paint industry produces a huge variety of
products that protect, preserve, and also beautify
the objects to which they are applied.
• Typical products include architectural coatings
(e.g. house paints), industrial coatings (e.g.
automotive finishes, wood furniture and fixture
finishes), and special purpose coatings (e.g.
traffic paints, roof coatings).

9.  Titanium Dioxide (TiO2) :
Provides
excellent hiding power and whiteness.
Available as a solid (powder) or liquid
(slurry).
 Zinc Oxide:
Controls mildew, resists ultra-
violet light Resists yellowing
Titanium dioxide is the world's primary pigment
for providing whiteness, brightness and
opacity. Prime Pigments

10. • Fillers are a special type of pigment that serve
to thicken the film, support its structure and
simply increase the volume of the paint.
• Fillers are usually comprised of cheap and
inert materials, such as talc, lime, clay, etc.

11.  Extender pigments are added in order to reduce
the cost of a paint formulation. They are also
used to modify the flow (viscosity), sedimentation
stability and film strength. Most extenders appear
white and possess a refractive index similar to
commonly used binders. Majority of them occur
naturally and others can be produced
synthetically. Aluminium silicate, magnesium
silicate (talc), silica, calcium carbonate
(synthetic and natural) and barium sulfate are
some commonly used extender in paints and
coatings.

12. The main purpose of the solvent is to adjust
the viscosity of the paint.
• Water is the main vehicle for water-based
paints.
• Solvent-based paints can have various
combinations of solvents as the vehicle,
including aliphatic, alcohols, etc.
• These include organic solvents such as
petroleum distillate, esters, glycol ethers, and
the like.

13.  Additives are mixed in very small amounts
and yet give a very significant effect on the
product.
Additives are used because:
 Modify surface tension.
 Improve flow properties.
 Improve the finished appearance.
 Improve pigment stability.
 Control foaming.
 Control skinning.

14. • Binds or glues ingredients (pigments and
additives) of paint together.
• Resin provides adhesion to the substrate.
• Resin provides durability & resistance properties:
• U-V resistance
• Moisture resistance
• Chemical resistance
• Stain resistance
• Fade resistance
• Chalk resistance
• Block resistance

15. The three most important binders (resins) used
in modern paints are:
 acrylic polymers (resins)
 alkyd polymers (resins)
 epoxy polymers (resins)

16.  are related thermoplastic or thermosetting
plastic substances created from acrylic
acid, methacrylic acid or other related
compounds. They are clear with good tensile
strength. Acrylic resins are impact and UV
resistant. They are used for structural and
decorative panels, adhesives, elastomers,
coatings, signs, and translucent tiles.

17.  are thermoplastic polyester resins created by
heating polyhydric alcohols with polybasic
acids. They have excellent electrical and
thermal properties and good chemical
resistance. They are low cost and used for
electrical insulation, electronic components,
putty fillers, and paints.

18.  also called polyepoxides, are a type of reactive
prepolymers and polymers which contain
epoxide groups. They have excellent chemical
and heat resistance and strong adhesion
properties. They are used for laminates,
adhesives, flooring, linings, propellers, and
surface coatings.

19. 1. Raw material: Resin, pigment and additive
agents are generally major components of
paint.
2. Mixing: Resin, pigment and solvent are
mixed to produce an even mill base.
3. Milling: Mill base produced at the pre-mixing
process is sent to the disperser to finely
disperse the pigment particles.

20. 4. Blending: Resin, additive agents and so on
are added to the mill base, the dispersion of
which is completed. Also, the color phase is
adjusted with color materials.
5. Filtering: Blended and toned paint is
filtrated.
6. Packing: Filtrated paint is packed into a
container.

22.  Some of the typical attributes required can include:
 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
 color stability (i.e. against visible and ultraviolet radiation)
 abrasion and scratch resistance
 durability
 flexibility
 easily cleaned

23.  GUI (Graphical User Interface) of paint
manufacturing process has been created using
Labview.
 With the help of Labview whole plant can be
virtually visualized.
 Process can be controlled and monitored i.e
level monitoring, valve indications, pump
indications, etc.
 Front panel & block diagram are easy to
handle.

24.  It is concluded that with the help of labview
and its various tool box different units of paint
manufacturing process has been designed.
With an additional monitoring and controlling
the level of various tanks & controlling of
mixer, valve & pump indications.
