This document discusses the properties of paint, varnish, and lacquer. Paint is a liquid or liquefiable composition that forms a solid polymer film. It is made of pigments, resins, drying oils, and binders. Good paint is cheap, easy to use, retains its color, uses extenders and diluents, and is generally applied to metal surfaces. Varnish is a hard, clear solution applied to wood to protect and gloss its surface. It is made of natural or synthetic resins, drying oils, and solvents. Good varnish dries by oxidation and polymerization, has a short duration time, reflects less light, does not use extenders, is applied to wood, and does

4. PAINT
Paint is any liquid, liquefiable
composition which is the form of
thin films of polymerization of
polyunsaturated oil are converts to
a solid film.

5. RAW MATERIALS
OF PAINT
PAINT=Pigment + Resin + Drying Oil + Binder
-from paint additives
-pigments both organic and inorganic color
-acrylic emulsion
-metallic driers for paint and ink
-alkyd resins for formulating paintings and
-specialized extenders

6. PROPERTIES OF A
GOOD PAINT
1.The paint should be cheap.
2.It should be easy and harmless to the user.
3.It should retain its original colour for a long
time.
4.Extenders are used in paint.
5.Diluents are used in paint.
6.Generally applied on metal surface.

7. VARNISH
Varnish is a clear, hard solution
that is principally applied to wood
to give it a glossy finish while
forming a protective film around
it.

8. RAW MATERIALS OF
VARNISH
VARNISH=Natural or Synthetic resin+Drying oil+Solvent
-Natural resin such as Chanch,Lac etc
-Synthetic resin such as Polyester,Polyamide etc
-Semisynthetic resin such as Cellulose acetate,
Cellulose nitrate etc
-Drying oil such as Soybean oil,Pum oil,Fish oil etc

9. PROPERTIES OF GOOD
VARNISH
1.It dries on the surface by oxidation,evaporation and
polymerization.
2.Its duration time is law.
3.It reflects less light.
4.Extenders are not used in varnish.
5.Applied on wooden surface.
6.Diluents are not use.

10. LACQUER
Lacquer is a clear or coloured
wood finish that dries by solvent
evaporation or a curing process
that produces a hard, durable
finish.

11. PROPERTIES OF GOOD
LACQUER
1.It dries on the surface by evaporation only
2.Its duration time is law.
3.It reflects lowest light.
4.Extenders are not used in lacquer.
5.Diluents are used.
6.It applied on both metal and wooden surface.
