2. What are the Functions of Paint ?
• Enhance the quality of natural and synthetic materials and
serves as a barrier against harsh environmental conditions
• Decorative paints: Improve the appearance and safeguard
builings and other objects
• Industrial coatings: Applied in factories to finish
manufactured goods such as cars

3. Components of Paints
• Pigments: Provides color and opacity
• Binder/Resin: Aids to keep the pigment in place
• Extender: Pigments that are bigger in size which helps to improve
bonding
• Solvent/Thinner: To reduce the thickness of paints for a wide variety
of uses
• Additives: Change the properties of paints in order to suit different
needs

4. What makes a good paint?
• Ability to be used in a variety of applications
• Good opacity
• Paint dries very quickly
• Protection against water and heat
• Good color stability against visible and ultraviolet rays

5. Future of Paints
• Water-based gloss paints: Intensive R&D work has been put into
develop water-based gloss paints that is greener and higher quality
• High solids paints: Figuring how to improve the structure of the
polymer used in paint with the objective to produce one that is of low
viscosity and good furnishing
• Powder coatings: It is commonly used in the form of sprays on
objects like bicycles. However, powder coating is usually used at high
temperature and thus more work is required to produce one that
works at low temperature.
