PAINTFROM A LAYMAN POINT OF VIEW IT IS SIMPLE A “ COATING MATERIAL”
TECHNICALLY DEFINED AS
“Paint is any liquid, liquefiable, or mastic composition which has continuous flow after application to a substrate in a thin layer is converted to an opaque solid film” . It is a Heterogeneous solution.
COMPONENTS OF PAINTS:
PIGMENT BINDER SOLVENT ADDITIVE
Pigment
Pigments are granular solids incorporated into the paint to contribute color, toughness, texture or simply to reduce the cost of the paint. Alternatively, some paints contain dyes instead of or in combination with pigments.
Pigments can be classified as either natural or synthetic types. Natural pigments include various clays, calcium carbonate, mica, silicas, and talcs. Synthetics would include engineered molecules, calcined clays, Blanc fix, precipitated calcium carbonate, and synthetic silicas.
Hiding pigments, in making paint opaque, also protect the substrate from the harmful effects of ultraviolet light. Hiding pigments include titanium dioxide, phthalo blue, red iron oxide, and many others.
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 made of cheap and inert materials, such as diatomaceous earth, talc, lime, baryte, clay, etc. Floor paints that will be subjected to abrasion may even contain fine quartz sand as a filler. Not all paints include fillers. On the other hand some paints contain very large proportions of pigment/filler and binder.
8
Binder or vehicle
The binder, commonly referred to as the vehicle, is the actual film forming component of paint. It is the only component that must be present; other components listed below are included optionally, depending on the desired properties of the cured film.
The binder imparts adhesion, binds the pigments together, and strongly influences such properties as gloss potential, exterior durability, flexibility, and toughness.
Note that drying and curing are two different processes. Drying generally refers to evaporation of the solvent or thinner whereas curing refers to polymerization of the binder. The term "vehicle" is industrial jargon which is used inconsistently, sometimes to refer to the solvent and sometimes to refer to the binder. Depending on chemistry and composition, any particular paint may undergo either, or both processes. Thus, there are paints that dry only, those that dry then cure, and those that do not depend on drying for curing.
Paints that cure by oxidative cross linking are generally single package coatings that when applied, the exposure to oxygen in the air starts a process that cross links and polymerizes the binder component. Classic alkyd enamels would fall into this category. Oxidative cure coatings are catalyzed by metal complex driers such as cobalt naphthenate.
Paints that cure by catalyzed polymerization are generally two package coatings that polymerize by way of a chemical reaction initiated by mixing resin and hardener, and which cure by forming a hard plastic structure. Depending on composition they may need to dry first, by evaporation of solvent. Classic two package epoxies or polyurethanes would fall into this category.
9
Solvent
The main purposes of the solvent are to adjust the curing properties and viscosity of the paint. It is volatile and does not become part of the paint film. It also controls flow and application properties, and affects the stability of the paint while in liquid state. Its main function is as the carrier for the non volatile components. In order to spread heavier oils (i.e. linseed) as in oil-based interior house paint, a thinner oil is required. These volatile substances impart their properties temporarily—once the solvent has evaporated or disintegrated, the remaining paint is fixed to the surface.
Water is the main diluents for water-borne paints.
Solvent-borne, also called oil-based, paints can have various combinations of solvents as the diluents, including aliphatic , aromatics ,alcohols, ketones and white spirit. These include organic solvents such as petroleum distillate, esters, glycol ethers, and the like. Sometimes volatile low-molecular weight synthetic resins also serve as diluents. Such solvents are used when water resistance, grease resistance, or similar properties are desired.
Additives
Besides the three main categories of ingredients, paint can have a wide variety of miscellaneous additives, which are usually added in very small amounts and yet give a very significant effect on the product. Some examples include additives to modify surface tension, improve flow properties, improve the finished appearance, increase wet edge, improve pigment stability, impart antifreeze properties, control foaming, control skinning, etc. Other types of additives include catalysts, thickeners, stabilizers, emulsifiers, texturisers, adhesion promoters, UV stabilizers, flatteners (de-glossing agents), biocides to fight bacterial growth, and the like.
Additives normally do not significantly alter the percentages of individual components in a formulation.

RESINSResin is a natural or synthetic compound which begins in a highly viscous state and hardens with treatment. Typically, resin is soluble in alcohol, but not in water. There are a number of different classes of resin, depending on exact chemical composition and potential uses. There are numerous applications for resins, ranging from art to polymer production, and many consumers interact with products which contain resin on a daily basis.
Natural resin comes from plants. A classic example is pine sap, which has the characteristic sharp odor of terpene compounds. As anyone who has interacted with pine sap knows, the substance is very viscous, but it hardens over time. A number of other plants produce resins, and plant resins have been used by humans for thousands of years. Some plants exude a similar substance called gum or gum resin which does interact with water. Gum tends to be softer and more malleable than resin.
Plant resin can be clear to dark brown in color, and it varies in opacity and hardness. Some plant resin is also extremely volatile, since it contains unstable compounds. Misidentification of resinous trees can sometimes lead to unfortunate accidents, since some resins contain heptanes, flammable and potentially explosive hydrocarbons. The popular decorative material amber is fossilized plant resin. The rich golden color of amber is a common shade for plant resins, but amber can also be found in more rare colors, like blue.

Procedure to keep Document of Passed batches and operation in Q.C.
In case of Passed batch cards Three type of Indexing is used. First type of Indexing is maintained according to the batch no. of a certain batch . The corresponding Register is called R/S(Retain/ Sample ) Copy.
Information can be found from this Copies are name of the Passing Chemist. Date of Passing and amount of retain sample kept (200ml/500ml.)
2nd type of indexing is maintained according to the quality no. Here one can found all the necessary details of a certain batch . The corresponding Cards are called Test Card.
3rd type of indexing maintained according to a curtained according to a certain date. The corresponding Copy detail daily Pass Book. From this Copy one can obtain the various batches of various qualities passed in a certain date.
To keep document about the operation a separate Copy is used and The name of the Copy is Daily Report Copy.
At the end of Working Day , Q.C. chemist first arrange the batch cards in the increasing order of their batch no. In the daily Report Copy .
To keep documents about the analytical works (for example of analysis Zinc- Chrome, Red- Oxide, Purity of H3PO4) Another Copy called Analytical Copy is used.
To keep document about the passed consignment of Passing material another register is used. Passing of consignment in SAP of packaging item is conducted with the help of this Copy.

Conclusion of the Project :-
I have seen 46.67 % problem are coming from Viscosity. So, Firstly Should be focus to reduce the Viscosity adjustment problem. Also I have observed from Cause & Effect Diagram some reason may be possible to sort out the problem. Which will also increase the RFT %.
