The document discusses the key raw materials, manufacturing process, and quality control for paint production. The main raw materials are pigments, solvents, resins, and additives. The manufacturing process involves mixing the raw materials, dispersing the pigments, thinning the paste, quality control testing, canning the paint, and packaging for distribution. The process aims to produce paint with the proper density, dispersion, viscosity, color fastness, hiding power, and other desired characteristics.

3. I. Raw materials
II. The manufacturing process
III. Conclusion

4. • Components:
– pigments
I. Raw materials
– solvents
II. Manufacturing
process – resins
III. Conclusion – various additives

5. • The pigments
– white pigment > titanium dioxide
I. Raw materials – black pigment > carbon black
II. Manufacturing – reds > iron oxide and cadmium sulfide
process
– yellows and oranges > metallic salts
III. Conclusion – blues and greens > iron blue and
chrome yellows

6. • The solvents
– various low viscosity, volatile liquids
I. Raw materials
II. Manufacturing
process
– include petroleum mineral spirits and
aromatic solvents such as
III. Conclusion
benzol, alcohols, esters, ketones, and
acetone

7. • The resins
– natural resins > lin-seed, coconut, and
I. Raw materials
soybean oil
II. Manufacturing
process
III. Conclusion
– synthetic resins >
alkyds, acrylics, epoxies, and
polyurethanes

8. • The additives
– many purposes
I. Raw materials – calcium carbonate and aluminum
silicate > fillers that give the paint body
II. Manufacturing
process and substance without changing its
properties
III. Conclusion
– Other additives produce certain
desired characteristics

10. 1) Making the paste
• Premix of the pigment with
I. Raw materials
resin, solvents and additives
II. Manufacturing
process
III. Conclusion

11. 2) Dispersing the pigment
• mixture for most industrial and some
I. Raw materials
consumer paints:
II. Manufacturing
process
III. Conclusion – transportation into a sand mill
– filtration

12. • For 90% of the water-based latex
paints designed for use by individual
homeowners:
I. Raw materials
II. Manufacturing – high-speed dispersion by a tank
process
– high-speed agitation by a circular
III. Conclusion

13. 3) Thinning the paste
• Transfer to large kettles
I. Raw materials
II. Manufacturing
process • Bustle with the proper amount of
III. Conclusion solvent

14. 4) Quality control
• Inspection to a finished paint for its
I. Raw materials
density, dispersion, and viscosity
II. Manufacturing
process
III. Conclusion • Study for bleed resistance, rate of
drying, and texture

15. • The different tests:
– color
I. Raw materials
– resistance of the color to fading
II. Manufacturing
process – paint hiding power
III. Conclusion – gloss

16. – mar resistance
– adhesion
I. Raw materials
– scrubbability
II. Manufacturing
process – weathering
III. Conclusion – fire retardancy

17. 5) Canning the paint
• empty cans are rolled horizontally onto
I. Raw materials
labels
II. Manufacturing
process • lids are placed onto the filled cans
III. Conclusion • the lids are sealed
• the handles are cut and shaped

18. 6) Packaging and dispatching
• Cans (usually four) are boxed and
I. Raw materials
stacked before being sent to the
II. Manufacturing
process warehouse
III. Conclusion

19. • A process rather polluting so paint
manufacturers treat their waste or
I. Raw materials recycle them.
