Thiruvananthapuram Industrial Pollution

Location:Kerela, India
Region:South Asia,
Source:Chemical Manufacturing
Transmission:air, water
Potentially affected people:23,234,707 in district

The problem

Since 1946 Travancore Titanium Products Ltd. (TTP) has been producing titanium dioxide and has become the leading manufacturer of anatase grade titanium dioxide in recent years. It has been operating close to a beach for several years without an effluent treatment plant. The factory has its own sulfuric acid plants and generates around 120 tons of concentrated sulfuric acid everyday which is dumped into the Arabian Sea directly without any prior treatment. pH of the effluent generated by TTP is always around 1 indicating very high acidity.
Health Impact

According to a study undertaken by the National Institute of Environmental Health, Thiruvananthapuram, people living near the industrial zone showed respiratory problems, watery discharge from eyes, skin problems and increased incidence of oral cancer compared to other areas under the study. An 8.3% increase in respiratory diseases like tuberculosis, wheezing, coughing and hyperactivity of the respiratory canal was observed in residents in the vicinity of the TTP industrial unit when compared to other areas.

The prevalence of diseases in the industrial zone were as follows: 29% Respiratory diseases 11% Gastric problems 10% Skin problems 20% Eye problems 18% Cardiac problems 12% Others

India's Powder Market
A survey
We often receive calls and email from our the Powder Manufacturers inquiring about the size of the powder market of India.

Earlier if you recall, we use to do an annual analysis of the market and shared the information and the analysis with our viewers . However, since the last few years most of the powder companies have stopped revealing their annual production figures publicly. The reason they give is ‘policy matters’

There is a need to know the size of the Indian powder market but its more of a guess work now.

To generate an authentic figure we need your help. Each one of you will be having some bits of information, some pieces of the jigsaw puzzle to contribute the making of a complete picture.

This newsletter will reach most of the people in the powder coating field. Kindly fill up some of the details in the survey form on this link. You may or may not reveal your identity.

In a few weeks time we will try to analyze the data and create some comprehensive information out of it. As always, the information will be freely available.

We need your input. Help us to help you.

Ceramic Coatings May Protect Jet Engines from Volcanic Ash
ScienceDaily (Apr. 13, 2011) — Last year's $2 billion shutdown of European airspace following a volcanic eruption in Iceland alerted everyone to the danger that ash clouds can pose to aircraft engines. Now, researchers have discovered that a new class of ceramic coatings could offer jet engines special protection against volcanic ash damage in the future.

For a study published online in the Early View edition of the journalAdvanced Materials, the researchers tested two coatings that were originally developed to keep airborne sand from damaging jet engines, and found that the coatings also resist damage caused by ash deposits.

"Of course, it's best for jets to avoid ash in the first place," said Nitin Padture, College of Engineering Distinguished Professor at the Ohio State University, who led the study. "That's not always possible. We determined that these coatings could offer sufficient protection against small amounts of ash ingested by the engine over time."<more>

China Consumed Some 1.4 Million Tonnes of TiO2 in 2010
GUANGZHOU, China - According to the latest research data from China Chemicals Market (CCM), a Chinese consulting company based in Guangzhou, China, the total capacity of China’s titanium dioxide (TiO2) represents approximately 30 percent of world capacity. In 2010, the total capacity of China’s TiO2 reached 2,000,000 tonnes, and annual production reached 1,470,000 tonnes. As a result, China has become the largest producer in the world.

China has also become the largest consumer of TiO2 in the world. In 2010, the consumption of TiO2 in China exceeded 1,400,000 tonnes.

Due to the supply shortage in the European market, the export volume of China’s TiO2 increased rapidly, making the first favorable balance of trade in May 2010.

Driven by growth of the macro economy, the demand for China’s TiO2 is growing rapidly, providing opportunities for TiO2 and downstream industries such as coatings, rubber and plastic. Demand for TiO2 is expected to grow at about 10 percent annually in the coming years. <more>

Researchers from Chinese Academy of Sciences Develop a Reflective Coating
Scientists in China have made a reflective coating with a structure that mimics the underside of a poplar tree leaf. The coating could be used on the outside of buildings to counteract the heating effect of carbon dioxide emissions, reducing the energy needed to cool the building from the inside.
Yanlin Song and colleagues from the Chinese Academy of Sciences, Beijing, mimicked the structure of the leaf's lower surface using polymers spun into reflective films consisting of long, hollow uniform fibres.
The underside of the poplar leaf is better at reflecting light than the top. This is because of the 'cool roof' effect, in which a layer of hairs on the underside reflects the light, so that less heat penetrates the leaf. The leaf turns over in strong sunlight to reveal the underside and as the light is being reflected rather than absorbed, the leaf appears white. 'Normally, the poplar tree looks green, but sometimes in the summer, the tree shows a white cast,' says Song.<more>

Pinhole Defects in Powder Coating Hot Dipped Galvanized Steel

Hi Joe...first of are you?
I’m Sanjay Sapkal - Surface Coating Technologist working with one of upcoming security solution industry in India named A1 FENCE PRODUCTS CO. About one year back we had installed a powder coating plant with advanced facilities like Nanochemicals in the pretreatment (as a multi-metal PT) , set up for dual coating, Electrostatic grade PVC coating on hot dipped galvanized surfaces. One of my colleagues, Mr Vivek Soley gave me your reference. He is very good friend of mine.

Can you help me with the following:

1. What specific precautions need to be taken during the process while applying the powder coat on HDG surface?

2. Is passivation during HDG process cause for pinholing?

3. We are going to develop degassing powders? Is it a right solution?

4. Is there any possibility of affect the pretreatment line chemistry for pinholing on HDG surface?

5. Is there any user friendly repairing method of PVC powder coating OR suggest any practical method of repairing? Recoat the PVC coating?

6. Do have any info on any plant in India with a similar application?


Sanjay Sapkal

Dear Sanjay,

Thank you for your questions concerning powder coating processes over hot dipped galvanized
substrates. Zinc coating on steel via the HDG process can be quite variable in quality and can be very difficult to successfully powder coat.

Let’s examine the mechanism first then we can explore and recommend solutions to the problem. First it is obvious that the pinholes in the powder coating finish are the result of gas escaping during the melt, flow and cure of the powder coating. The gas passes through the molten coating creating a rupture in the coating surface. The rupture remains open as the powder hardens resulting in a “pinhole” defect.

The nature of the gas is not entirely known and is cause for speculation. Could it be air entrapped in the pores of the galvanized structure or water retained in micro-cavities that evolves as water vapour during powder cure? Or could it be volatile hydrogen gas caused by a reaction of zinc with an acid pickling stage in the pretreatment? All theories have been posited yet none have been conclusively verified.

Regardless of the nature of the gas the fact remains – HDG causes intermittent pinhole defects in

powder coatings unless precautionary measures are employed. Here are the best practices to eliminate or minimize the occurrence of these defects:

1. Preheat the galvanized substrate to 175 to 185°C prior to applying the powder coating. Apply
the powder while the part is still warm. Regardless of what the source of the gas is this will
significantly reduce the outgassing issue.
2.  Use a “gassing” resistant powder coating. Outgas relief additives exist that can be incorporated in powder coatings. In theory these materials allow the volatile gas to exit the coating and then collapse back into the coating surface thereby filling the rupture. A number of additives suppliers specifically identify these materials as “anti-gassing” or “degassing” compounds.
3. Avoid applying excessive powder coating. Apply the powder per your supplier’s
recommendations. Keep from applying powder coatings greater than 4 mils (100 microns).
4.Use a source of high quality galvanized steel. Undoubtedly inconsistencies in galvanizing
composition, process, age and thickness can contribute to inconsistent powder coating
performance. Understand your vendor’s process, their quality programme and how they
handle the substrate before it arrives at your facility. Have them tighten up their processes as
5. If you use an acid etch as part of your pretreatment process, consider eliminating this step. Acid
etching can create hydrogen gas.
6. Ensure that your parts are fully dry before applying the powder coating. Preheating the parts
should accomplish this.

As for repairing a PVC powder coating that exhibits outgassing defects, I would first attempt reheating the part to see if the thermoplastic PVC will reflow into the pinholes. If this does not eliminate the defects then I would attempt recoating with the same PVC powder. I would carefully clean the surface with a suitable solvent (acetone or alcohol) before recoating as there may be handling contaminants and/or plasticizer or wax on the surface.

As for knowledge of another Indian operation doing this – indeed there are many. I do not know any
personally but I think a search on the internet should provide you with the names of companies doing the same work.

I hope that my insights into your problem help. Please let me know your progress.

Kind Regards,


Gloss Variations: Gas-Fired vs. Electric Oven

Dear Joe,

We have different results in gloss value using my electric oven versus the gas fired oven of my

customer. The gas fired oven gets lower gloss than our electric oven. The metal temperature of the parts is the same (185°C) in each oven and we have verified this with an Easy Track Oven Profiler temperature recorder. The product is a semi-gloss hybrid powder with a target gloss of 35-40%. My concern is there an effect in gloss the fumes of the gas fired oven? My knowledge is only color affects using gas fired oven turns into yellowing. Does a gas fired oven also produce variations in gloss versus an electric oven?

Marco Reyes
Manila, Philippines

Dear Marco,

Gas oven environments can be highly variable depending upon the quality and consistency
of the incoming gas and also the quality and consistency of the combustion in the burner.
Furthermore the amount of exhaust set in your oven can affect the quality of the powder
coated finish.

The way to qualify effect of the gas fired oven environment can be accomplished by isolating
the powder from the oven environment whilst still allowing it the same bake. This can be
done by powder coating one test panel and placing it in a closed tin can. Puncture 3 or 4 small
exhaust holes at the top side of the can to allow for escape of volatiles. Powder coat another
test panel and hang it outside the tin can and place the can into the oven.

After stoving both panels examine the color, gloss and appearance of each finish. If the
gas environment is excessively altering the coating the effects should be very obvious. You
can “map” an oven by placing multiple panel-containing tin cans in various locations in your

I hope that this helps and please let me know what you find.

Best Regards,
