Dispersion as a chemistry – So what happened 15Y back Asian nerolac and berger, they used to make their own dispersions, however the probs they were facing was is that when lets say u buy pigments from sudarshan. Biggest prob is tinctorial strength (strength of imparting color)
When u put x grams of pigments in a paints the shade has to be exactly as standard thats given to u but that was not happening. It had variation of about 2-3%. As a house owner u want to paint wall blue – u get 2 boxes of blue from asian paints. And after the 1st coat from first box and now u open 2nd box and you would notice that tonal variation is seen at this pt. About 15-20Y and possibly still u use to apply putty first and then 1st coat of paint and then let it dry and then a 2nd coat and 3rd so on.That was 1 of the reason paint companies had grown in volume.
Now the way dispersion chemistry has changed and coz of dispersions u are able to get exact color and strength across the batches manufactured. Now there is no need to use putty and now u might just need 1.5 coats of paints. So its in a way double whammy for paint companies as vols go down. And there are few companies that are helping paints companies with these dispersions.
Clariant is one name which are doing this manufacturing of dispersion with sync Paint companies – they buy pigments or make their own pigments and they will create the dispersions for each colors. And as per standards by paint companies they will do color matching with spectro photometer and then this finally goes for packaging like moldtek pkging. This is one new step in the value chain that got added in last 10-15 Y as paint companies wanted consistency coz dispersions companies are very important.
Eg asian buys pigments from 3 companies then it becomes impossible for all 3 pigments suppliers to match the pigments. So it comes upon dispersion companies to create an end shade of all these 3 pigments. Coz paint companies will catch their neck if match doesn’t happen.
Its like an important sub segment in the value chain. Obviously cyclical as it depends on pigments and paints industry. But its a niche as stickiness is there. Its a critical thing in the chain and OEM won’t go anywhere else.
Benefits of Dispersion : Time reduction + Cost reduction + Reduction in size of operations + consistent quality
Dispersion market : Paints 40% Plastics 15% Inks 35% approx
If dispersion guys go into pigment powders that would mean self-sufficiency and far better quality control.
