What Is Paint?

---

Pigment +Resin (Binder) +Additives + Solvents (Thinners)

Resins: - The heart of any paint system. They hold together the individual pigment particles and contribute most of the physical properties of the dried paint film. Ie, Hardness, Flexibility, Durability etc. Cohesion of coatings material. Adhesion to substrate.

Basic Resins for Paints & Coatings

Polyester (PE)

Epoxy Resin

Acrylic Resins

PVC Plastisol

Polyvinylidene Fluoride (PVDF)

Polyamide Resins

Alkyd Resin

Silicone-modified Polyester (SMP)

Cross-linker resins

Amino resins

Polyurethane

Provide colour, opacity, and anti-corrosive properties. Colour & Hiding Power.

1. Color

2. Opacity

3. Gloss

4. UV Absorption / Protection

5. Hardness / Flexibility

6. Anti-Corrosion

Types Of Pigments:

1. Titanium Dioxide Pigments

2. Colored Pigments

3. Inorganic

4. Organic

5. Pearlescent Pigments

6. Anti - Corrosive Pigments

Pigments Classification:- 

1. Inorganic Pigment

        Dull Color

        Excellent UV resistance

        Outstanding Chemical resistance

2. Organic Pigment

       Bright Colors

       High Tint Strength

       Poor UV resistance

3. Aluminium & Pearlescent Pigments

      Platelet-shape particles that reflect 

      incoming Light

      Aluminium Flake - Opaque

      Mica particles

      Translucent particles

      Sparkling effect

4.  Anti-Corrosive Pigments

      Used in Primer coats

      Create anti-corrosive effect

Main function is to mix all the ingredients. Help during the paint application stage. Help as the flow and general film properties if the dried coating. These lliquids dissolve resin without chemical reaction which is volatile during film formation.

1. Dissolve the binder in the paint

2. Have compatibility with binder

3. Maintain stability of paint

4. Prepare paint for application

5. Evaporate after drying

6. Assist in flow and leveling of paint

They help to disperse pigments, Help for curing the coating and even remain in the dried film to provide extra durability. Improves the properties of the paint film. Used in very less quantity. Improves the desired properties and remove undesired properties
