What is Paint?Paint is any liquid, liquefiable, or mastic composition which after application to a substrate in a thin layer is converted to an opaque solid film. It is most commonly used to protect, color or provide texture to objects.
What is paint made of?• Pigments• Resins• Solvents• Additives
Pigments
• Pigments give color to paints• Both natural and synthetic, exist• average particle size can vary from 0.2 to 10
(micro meters)
Pigments
• True pigments exhibit capacity or hiding power in varying degree whereas extenders are practically transparent
Pigments
Resin (Binder or Film – Former)
• Resins helps paint dry and adhere• responsible for the protective and general
mechanical properties of the film
Resin (Binder or Film – Former)
• Convertible Resins• Thermosetting Resins (STOVING RESINS)• Non-convertible Resins
Solvents (Thinners)
• Solvents make paint easier to apply• low viscosity, volatile liquids• include petroleum mineral spirits and aromatic
solvents such as benzol, alcohols, esters, ketones, and acetone
Additives
• Additives serve as everything from fillers to anti-fungicidal agents
Example Black Stoving PaintPigment:
Carbon Black 1.6%
Resins:
Coconut Oil 49%
Alkyd Resin 10%
Melamine Resin 19%
Solvents:
Xylene 15%
Ethylene Glycol 2%
Iso-Butanol 3%
Additives:
Dispersing aid 0.4%
Types of Paint• Primers • Sealers • Undercoats • Finishing Coat • Stoppers and Fillers
Paint Manufacturing Process
1. Making the paste2. Dispersing the pigment3. Thinning the paste4. Canning the paint
Paint Manufacturing Process
Equipment• Attritor• High Shear Mixer
Attritor
• The material to be ground and the grinding media are placed in a stationary, jacketed grinding tank
• shearing and impact forces
• Media= Flint
Attritor
High Shear Mixer
• Mixes fluids having higher viscosities
• Used in paint industry and edibles like chocolates and ice cream
