3) Classifications:  
Emulsion paints for  interior  use are classified into the following:  
Class (A) – premium – semi gloss – gloss   
Class (B) – medium – matt – silk 
Class (C) – economy – matt 
All the above classes are divided into three types of bases, base (A ) for light colors, base (B ) 
for medium colors and base (C ) for dark colours .  
 
4) Terms & Definitions:  
 
4.1  Emulsion  
A mixture formed by  the incorporated of two liquids which are normally immiscible. One liquid 
is dispersed in the other in the form of minute drops. If the droplets remain permanently 
dispersed the emulsion is said to be stable and certain compound s are added as stabilizers of 
their power to keep the droplets dispersed.  
 
4.2  Emulsion for paints:   
A dispersion of 2 or more organic monomers which are copolymerised  and dispersed in water. 
The dispersed phase is in the form of minute drops. The droplets remain permanently 
dispe rsed. The emulsion is said to be stable and certain compound are added as stabilizers 
because of their power to keep the droplet dispersed.  
 
4.3  Vehicle : 
The liquid portion of the paint in which the pigment is dispersed and it is composed of the 
binder an d the thinner if any.  
 
4.4  Binder : 
The n on-volatile portion of the  “Vehicle” of a paint. It binds or cements the pigments particles 
together and the paint film as a whole to the material to which it is applied.  
 
4.5  Thinner : 
Volatile liquids added to pai nts or varnishes to facilitate application and to aid penetration by 
lowering gather viscosity. They should be completely miscible with the paints or varnish at 
ordinary temperature and should not cause precipitation of the non -volatile portion either in t he  
6 
 container or in the film during drying. For some purposes thinner containing a small proportion 
of non -volatile material may be used.  
 
4.6  Pigment  
The insoluble dispersed particles in a paint which give the dried film its characteristic 
properties of c olour and opacity.  
 
4.7  Base   
It is a semi -finished product which needs to be tinted to be a finished coloured product and it is 
classified as A base, B base, and C base depending on the required colour of final product.  
 
4.8  Opacity  
The ability  of a co at of paint to obscure (hide) an underlying surface.  
 
4.9  Drying time  
The time which elapses between the application of a coat of paint and the attainment of a 
specified dry state . 
4.10  Peeling (removal)  
The failure which occurs due to the bulging of a d ried layer of paint or varnish upon painting 
with another layer, and usually appears in the form of twists.  
4.10  Lifting (bulging)  
This is a failure which occurs in the paint or dried painted layer and usually appears in the form 
of wrinkles when painted with another layer above it.  
 
5) Characteristics & Requirements  
5.1      Composition : 
The emulsion paint shall consist of pigments with suitable extenders in suitable proportion in a 
medium consisting of any suitable stable synthetic polymer emulsion in water wi th other 
suitable ingredients as may be necessary to produce a material so as to satisfy the 
requirements of this standard.  
 
5.2 Application properties : 
The substance should be applicable by a regular brush or roller or by spraying as 
recommended by the manufacturer (Technical Data Sheet TDS). The paint layer should not 
reveal any lumping, foam or rough protrusions of the paint film or any undesirable properties. 
Further, the thin paint layer should not result in any breakdown, softening or any deformity 
upon painting with another layer of a surface which has been painted earlier, after the lapse of 
12 hours as a maximum of air drying.  
 
 
  
7 
 5.3 Condition in the container :  
The material shall have no evidence of biological growth, levering, skinning, and putrefac tion, 
hard settling of the pigment, lumps, or corrosion of the container. Any settled pigment shall be 
readily dispersible in the liquid medium by stirring with paddle to produce smooth 
homogeneous emulsion paints, free from persistent foam. The material s hall have no irritating 
or offensive odor.  
 
5.4 Odour :  
The odour of the paint shall not be putrid or otherwise offensive or irritating before, during and 
after application. There shall be no residual odour after 24 hours of drying.  
5.5 Resistance to biological gr owth:  
The paint in the container shall not reveal any growth of fungi during the validity period stated 
on the container, taking into consideration the storage properties set under clause 5.6 . 
 
5.6 Storage properties:  
The paint shall retain its properties in t he original sealed container when kept away from direct 
sunlight for a period of 12 months without any skinning forming on the surface or thickening 
happening during this period. If there is any settled pigment, it shall be easily stirred.  
 
5.7 Colour fastnes s to light:  
The paints shall show no darkening or other changes in appearance when subjected to 72 
hours exposure to direct sun or any other light  source .  
 
5.8 Appearance of dried film (finish):  
When a film of the paint has dried for the specified drying peri od, it shall have, smooth, firmly 
adherent and substantially free from brush marks or sagging or wrinkling, and shall in no way 
be inferior as regards finish to a film prepared in the same way and the same time from the 
approved reference sample.  
 
 
5.9 The tab les below (table  1 to table 7) shows the specified  requirements of class (premium, 
medium, economy) of emulsion paint s for interior  use for white colour and different base type, 
as well as imported paints which are pre -coloured  by country of origin accordi ng to colour 
shade and base type specified  by customer .
