## Basic Terms for Paint Ingredients and Chemicals(1/3)

Painting anything make our surrounding more attractive. It gives attractive look and protect surfaces of wall, wood, metal etc. For that you need to know basic terms of paint ingredients and chemicals.

#### 01. Accelerator:

One type of resin based additives added in paints and varnishes to speed up the curing process or cross-linking of system.

#### 02. Acoustic Material:

A soft or aerated material lightly bound or bonded to form a soft, absorbent coating or fabricated slab to absorb and isolate sound and reduce echoes. It is used where reduction of the noise is needed. i.e. for commercial purposes and engineering structures.

#### 03. Alkyd Resin:

It is a synthetic resin resulting from the polyhydric alcohol and polybasic acid. It is used in paint as a binder. It gives protecting coatings with good weathering properties. It is an important ingredient in many synthetic paints due to their versatility and low cost. The alkyd resins may be dissolved/diluted in mixtures of organic solvents, water, etc. It makes the paint yogurt thick and brushes dipped in it carries more paint to the surface.

#### 04. Amino Resin:

Amino resins are thermosetting synthetic resin formed by the interaction of amino (-NH2) group with the aldehyde in the presence of solvents.  It is used in paint coatings due to its inherent properties like solubility in water, chemical resistance etc.

#### 05. Anti-Corrosive:

Anti-corrosives are added in the paint for preventing corrosion. It is specially formulated with a focus on retarding the rusting of iron or steel in high-risk environment.

#### 06. Anti-Fouling Compositions:

A coating material formulated for preventing the growth of sub aquatic organisms such as algae, barnacles, etc. A paint formulated from this composition is mostly used in underwater marine surfaces.

#### 07. Anti-Settling Agent (Suspending Agent):

Anti-settling agents are incorporated in the paint to keep pigments in suspension. It prevents pigments or other finely divided solid particles from settling during storage.  It also maintains the proper viscosity of the coating formulation.

#### 08. Anti-Skinning Agent :

Anti-skinning agent is added to a paint with a view to preventing or retarding the formation of an insoluble skin on the top of the surface in the paint container. This may happen due to polymerization or oxidation reactions in paint container.

#### 09. Binder:

Binder means to make other substances or materials stick or mix together. Binders play very important role in paint. They bind the pigments, provide adhesion, integrity and toughness to the dry paint film. It is an important ingredient that affects the almost all properties of coating such as resistance to blistering, cracking, peeling, scrubbing, chalking, fading, flow of paint, film build, gloss development etc.

#### 10. Bituminous Solution:

Bituminous solution has an excellent adhesion and corrosion properties and it is used as an anticorrosive in paint industry.

#### 11. Bituminous Varnish:

Bituminous varnish is a dark transparent varnish containing asphalt/ bituminous ingredients. It is a solution of oil bitumen in organic solvents. It is mostly used to protect the metallic surfaces.

#### 12. Blown Oil:

Blown oil is a drying oil obtained from thickened vegetable or animal oil. Blown oil has been partially oxidized by blowing with stream of air or oxygen and therefore thicker and fast drying. Most common blown oils are castor, linseed, rapeseed, whale, fish oil etc.

#### 13. Boiled Linseed Oil:

Boiled linseed oil is not “boiled” as the name suggest. It is chemically modified oil by adding metallic components in raw linseed oil. It is also known as drier to encourage faster drying.

#### 14. Boot-Topping Composition:

Boot-topping compositions are incorporated in paint coating to prevent corrosion and marine growth. They are obtained from an anti-corrosive and anti-fouling compositions. Paint made from this composition is applied on a load-line area (air-water interface) of ship hulls. It is usually black in colour.

#### 15. Bronzing Lacquer:

Bronzing lacquer is a transparent lacquer designed for use on metal surfaces for industrial product finishing. It has properties to brighten metals, to preserve their lustre and enrich colour.

#### 16. Bronzing Medium or Liquid:

Bronzing medium is a vehicle. It is either a varnish or a lacquer specially formulated for use as a binder with gold bronze or aluminium powder.

#### 17. Chlorinated Rubber:

Chlorinated rubber is a chlorinated thermoplastic resin contain about 65 % chlorine. These additives are mostly used as solvent solution in paint industry.  It is an environment friendly resin having high hardness. It is mostly used for making fire-proof and ant-corrosive paints because of high chlorine content.

#### 18. Copal:

Copal is a hard-natural resin formed because of extruding of various tropical trees. There are various types of copal in paint industryThe hard fossil types are the basis of all copal varnishes. The softer types frequently obtained by the tapping live trees being mostly used for spirit varnishes. Congo copal is the main surviving member of the fossil class and Manila copal that of the spirit soluble class.

Cross-linking agents are incorporated during polymerization in the polymer chain. It reacts chemically with the molecular chains of a thermoplastic material and linking them together. It creates a more rigid structure resulting in an infusible product.

#### 20. Curing Agent:

Curing agent is also known as a “hardener”. A set of additives incorporated in paint to harden a surface. It facilitates the bonding of the molecular components of the material. If the molecular bonds are strong, material surface becomes harder.

#### 21. Driers:

Driers are set of substance incorporated in relatively small proportion in oil type coatings, varnishes, alkyd paint etc. to accelerate paint drying time at ordinary temperature. These substances are usually compounds of lead, manganese, cobalt, etc.

#### 22. Drying Oil:

Drying oils are vegetable oils having the hardening and drying properties. Drying oils make tough film when applied in a thin layer and exposed to air (oxygen). These oils are major components in varnishes, oil paints, anticorrosive paint etc. Drying oils include Poppy seed oil, Perilla oil, Linseed oil, Tung oil, Walnut oil etc.

#### 23. Epoxy Resin:

Epoxy resins are thermosetting synthetic resins containing epoxies groups. They are formed by   cross-linking reactions of epoxide groups.  A common type is the resin made from epichlorohydrin and bisphenol A. Coating from this type of resins have high flexural strength and good filling properties when combined with filler.

#### 24. Extender (Inert Filler):

Extenders are finely ground natural inorganic material in powder pigments of low refractive index. Extenders are usually cheap and inert materials. Extenders are used as a constituent of paint to reduce the cost of paint formulation and to impart the paint properties such as flow, increase coverage, appearance, settlement of pigment on storage, film strength etc.

#### 25. Filler:

Filler is a thick pigmented material for filling fine cracks, holes, defects, pores in surface to obtain a smooth and even surface as preparatory surface for painting.
