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. (Message for the print media). A lot of efforts go into the compilation of these monthly e newsletters. Some of the contributions from our subscribers are exclusive.

Ceramic Coatings May Protect
Jet Engines from Volcanic Ash 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> |

 "Ask Joe Powder" "Ask Joe Powder" is a question and answer column authored by Kevin Biller of the Powder Coating Research Group. Mr. Biller has over 30 years experience formulating and manufacturing powder coatings. He welcomes your questions regarding powder coating technology. Please write to: askjoepowder@yahoo.com Kevin Biller The Powder Coating Research Group 15 W. Cherry Street, 3rd Floor Columbus, OH 43215 614-354-11988 www.powdercoatingresearch.com Pinhole Defects in Powder Coating Hot Dipped Galvanized Steel Hi Joe...first of all...how 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? Regards, 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 necessary. 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, Joe 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 oven. I hope that this helps and please let me know what you find. Best Regards, Joe |
