  1. 1. TO THE WORLD OF PAINTS WELCOME ICIS © Copyright - 2012, All Right are reserved
  2. 2. WHAT IS PAINT? A thin dry film so formed by this Solution is then applied to a surface which is used as a decorative or protective coating. “A paint is a Solution or suspension of pigment, binder and mineral solvent.”
  3. 3. Paint is used to protect, preserve, decorate, or add functionality to an object or surface by covering it with a pigmented coating. An example of protection is to retard corrosion of metal. An example of decoration is to add festive trim to a room's interior. An example of added functionality is to modify light reflection or heat radiation of a surface. Also the use of color to identify hazards or to identify the function of equipment and pipelines.
  4. 4. HISTORY OF PAINT Colour or Paints has been with us for more than 20,000 years. Evidence survives in early cave paintings and the ancient Chinese are considered to have brought its manufacture and use to a state of perfection tens of thousands of years ago. One of the earliest recorded Colour discoveries was made by Plato who discovered that by mixing two Colours, a third is produced, therefore changing the, 'manufacture', of Colour forever. 5000 years ago Blue Frit was the first synthetic pigment being produced by the Egyptians. Before the nineteenth century the word 'paint' was only applied to oil-bound types; those bound with glue were called 'distemper'.
  6. 6. Pigments are granular solids incorporated in the paint to contribute color. Fillers are granular solids incorporated to impart toughness, texture, give the paint special properties, or to reduce the cost of the paint. A distinction is usually made between a pigment, which is insoluble in the solvent (resulting in a suspension), and a dye, which either is itself a liquid or is soluble in its solvent (resulting in a solution). PIGMENT Pigments can be classified as natural and synthetic types.
  7. 7. The binder, or resin, is the actual film forming component of paint. It is the only component that must be present in paint. Binders can be categorized according to drying or curing mechanism. BINDER
  8. 8. The main purpose of the Solvent is to adjust the viscosity of the paint. It is volatile and does not become part of the paint film. It can also control flow and application properties, and affect the stability of the paint while in liquid state. Its main function is as the carrier for the non volatile components. SOLVENT MTO or Xylene is the main solvent for Industrial paints. Water is the main solvent for water-based paints.
  9. 9. Additives are usually added in small amounts to provide a significant effect on the product. Example: To modify surface tension, improve flow properties, improve the finished appearance, improve pigment stability, control foaming, etc. ADDITIVES Other types of additives include catalysts, thickeners, stabilizers, emulsifiers, adhesion promoters, etc.
  11. 11. PRIMER Primer is a preparatory coating put on materials before painting. Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted. PAINTS BASED ON APPLICATION
  12. 12. EMULSION Water-based paint used for painting interior or exterior surfaces. PAINTS BASED ON APPLICATION
  13. 13. LACQUER Lacquer is a clear or colored coating, that dries by solvent evaporation, usually a fast-drying solvent-based paint or varnish that produces an especially hard, durable finish. PAINTS BASED ON APPLICATION
  14. 14. An enamel paint is a paint that dries to an especially hard, usually glossy, finish. Enamel paints contain either glass powder or tiny metal flake fragments instead of the color pigments found in standard oil-based paints. Enamel paint is also mixed with varnish to increase shine as well as assist its hardening process. ENAMEL PAINT PAINTS BASED ON APPLICATION QDE - Quick Drying Enamel is an alkyd type paint that provides great durability while being noted as a fast drying paint. It is formulated to give a tough, durable, beautiful and high build film on wood and metal.
  15. 15. Wood stain is a type of paint that is very "thin," that is, low in viscosity, and formulated so that the pigment penetrates the surface rather than remaining in a film on top of the surface. Stain is predominantly pigment or dye. WOOD STAIN PAINTS BASED ON APPLICATION
  16. 16. PU Paint is an acrylic solvent-based coating that forms a seamless, non-porous, watertight film that repels water and prevents seepage. It is noted for its excellent adhesion and long-term durability. Creates a very tight film, serving as a moisture sealant for concrete and a stain inhibitor for wood. PU PAINT PAINTS BASED ON APPLICATION
  17. 17. Epoxy Paint is a high quality, two-component, epoxy- polyamide system that has exceptional adhesion to practically any surface including steel tanks, galvanized iron, pipelines, aluminum, structural steel, etc. Has excellent corrosion resistance and sealing properties. EPOXY PAINT PAINTS BASED ON APPLICATION
  18. 18. Oil paint is a type of slow-drying paint consisting of small pigment particles suspended in a drying oil. Oil-based Paint PAINTS BASED ON APPLICATION
  19. 19. Powder Coating is a type of dry coating, which is applied as a free-flowing, dry powder. The main difference between liquid paint and a powder coating is that the powder coating does not require any solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin." It is usually used to create a hard finish.

  20. 20. PAINTS CAN BE APPLIED BY: • Brush • Roller • Spray Gun
  21. 21. FAILURE OF PAINT The main reasons of paint failure after application on surface are the applicator and improper treatment of surface. Application Defects can be attributed to: Dilution This usually occurs when the dilution of the paint is not done as per manufacturers recommendation. There can be a case of over dilution and under dilution, as well as dilution with the incorrect diluent. Contamination Foreign contaminants added without the manufacturers consent which results in various film defects.
  22. 22. FAILURE OF A PAINT Peeling/Blistering Most commonly due to improper surface treatment before application and inherent moisture/dampness being present in the substrate. Cracking Cracking of paint film is due to the unequal expansion or contraction of paint coats. It usually happens when the coats of the paint are not allowed to cure/dry completely before the next coat is applied. Erosion Erosion is very quick chalking. It occurs due to external agents like air,water etc.
  23. 23. DANGERS OF PAINT Volatile organic compounds (VOCs) in paint are considered harmful to the environment and especially for people who work with them on a regular basis.
  24. 24. Environmental regulations, consumer demand, and advances in technology led to the development of low- VOC and zero-VOC paints.These new paints are widely available and meet or exceed the old high-VOC products in performance and cost-effectiveness while having significantly less impact on human and environmental health.
