UNIT I BINDERS, PIGMENTS AND OTHER RAW MATERIALS FOR PAINTS 9
Variable types of binders used in paint making – natural resins – shellac, rosin, oils and
rubber-chemistry and properties; preparation and properties of synthetic resins – alkyds,
phenolics, vinyls, amino resins, acrylics, epoxies, urethanes and silicones - Pigments and
Extenders – Inorganic, organic and metallic pigments and extenders-corrosion inhibiting
pigments-properties and functions.
UNIT II SOLVENTS 9
Solvents, additives, plasticizers and driers used in paints – solvency power, toxicity, Kauributanol
and aniline point values for solvents-various additives and purpose of each
considerations in formulation of a paint – concept of Pigment Volume Concentration and
volume solids – rheological characteristics of paint – water based paints – composition and
properties – factors affecting water dispersibility-Manufacture of paints – ball and pebble
mills, attritors, sand and bead mills, three roller mills.
UNIT III TESTING AND EVALUATION OF PAINTS 9
Liquid paints – Instruments involved in each test – fineness of grind, volume solids, specific
gravity, viscosity, consistency, wet film thickness, drying time - testing of physical properties
– dry film thickness, holiday detection, adhesion, hardness, flexibility, impact resistance,
abrasion resistance - testing of corrosion resistance – electrochemical tests, humidity, salt
spray, weather resistance, immersion test and field exposure test. Paint film defects –
identification and remedial measures.
UNIT IV SURFACE PREPARATION AND APPLICATION OF PAINTS 9
Methods of surface preparation – chemical and mechanical cleaning. Standards covering
them and instruments involved. Conversion coatings-phosphating, chromating of ferrous
and non-ferrous metals; application of paints – methods – brushing, dipping, roller coating,
air spray, airless spray, electrostatic spray.
UNIT V PAINTS FOR FUNCTIONAL APPLICATION 9
Paints for rural atmospheres, industrially polluted atmospheres, marine atmospheres
offshore applications, chemical paints, automobiles and air crafts. Coating for pipelines –
coatings for concrete, wood and plastics. ceramic coatings , powder coating- principle,
basics and application.
TOTAL : 45 PERIODS
