|DuPont to pay $670 million to
settle C8 lawsuits
Lawrence Moody said he is satisfied that he and 3,550 other people are finally getting justice.
"You just can't do that to people," the Washington County man said after DuPont and its spinoff company Chemours agreed to pay nearly $671 million to Mid-Ohio Valley people affected by a chemical used to make Teflon that causes cancer and a host of other health problems.
The settlement was announced Monday during the trial of Moody's lawsuit in U.S. District Court in Columbus. Chief Judge Edmund A. Sargus Jr. sent the jury home without a verdict.<more>

I don't know if you have covered this before. We notice that the cured powder does not stick readily to edges that have been cut by a laser. What are the causes of this and what can be done to overcome the adhesion issues?
Nope, this is a first time question. Cutting steel with a laser offers many advantages including precision, speed, less rejects and low labor costs. However one of the problems inherent to laser cutting is the blue oxide edge it leaves on carbon steel. Powder coatings don't like to adhere to this oxidized surface. Conventional iron or zinc phosphate pretreatments don't adequately penetrate the oxide to provide adhesion of the cured powder. This results in a loss of adhesion and the potential for serious corrosion problems.
There are a few paths to compensate for this shortcoming. One is to employ a more aggressive pretreatment process. Using a strong acid etch prior to the phosphate stage can attack the oxide layer enough to allow the phosphate to do its thing.
Another option is to avoid creating the oxidation by using nitrogen in the laser cutting process. It's more expensive than using oxygen but it minimizes oxidation from the laser and therefore allows a conventional iron or zinc phosphate process to provide a surface more amenable to adhesion of a cured powder.
A third option is physically abrading the edges. This can be accomplished either automatically (blasting or wheel abrading) or manually. If you opt for a blasting process it is imperative to keep your media clean otherwise you can contaminate the surface you are attempting to clean. ScotchBriteŽ pads or wheels work well but require additional labor. Keep in mind that these extra steps can be cost-prohibitive.
I hope this helps.
All the best,
We're looking for an epoxy powder that is resistant to D.O.T. 3 brake fluid, we are a manufacturer of stainless steel filters and a customer of ours uses D.O.T. 3brake fluid with our filters which we use an epoxy resin in our assembly of the filter.
D.O.T. 3 brake fluid is a tough one. Most hydraulic fluids act as a paint remover when exposed to an organic finish. Brake fluid will seriously attack conventional polyester and hybrid powder coatings Standard epoxies fare better but only a high performance epoxy will adequately withstand regular exposure to the D.O.T. 3 material. Epoxies formulated for decorative purposes don't have the chemical resistance needed to resist the aggressive solvating ability of the fluids used for hydraulic systems. Therefore I suggest you specifically ask your powder supplier for a brake fluid resistant epoxy. These have been commercially available for years so you shouldn't have a problem getting the right material for the job.

7th Leading International Trade Fair for Industrial Coating Technology from 17 through 20 April 2018 in Karlsruhe (Germany) with More Exhibition Floor Space
Strong Demand for Booth Locations at PaintExpo 2018
Oberboihingen, November 2016 Although it is only been seven months since PaintExpo 2016 closed with record breaking results, promoters FairFair GmbH are already able to report lively demand for exhibition floor space at the upcoming, leading international trade fair for industrial coating technology: at the beginning of November 2016, 170 companies had already made firm bookings for their booth locations at PaintExpo from the 17th through the 20th of April, 2018. With roughly 75,000 square feet, net exhibition floor space already amounts to more than 50% of the level reached at the last event. And thus for PaintExpo 2018, booth floor space offerings will be significantly increased.
PaintExpo 2016 received top scores and set new standards with regard to exhibitor and visitor numbers, as well as internationalism. With 10,522 visitors from 74 countries, the leading international trade fair for industrial coating technology observed an increase of 14.8%. And it's no wonder, because with its comprehensive overview of the industrial coating technologies market, PaintExpo is meanwhile the number one information and procurement platform for users from all over the world. 'PaintExpo is theglobal showcase of the painting industry, which makes it an absolute must for us. It's the most effective way to present our product range and new developments to international expert visitors, and we'll exhibit again in 2018 as a result', explains Andrea Ortelli, export manager for Italian paint manufacturer Arsonsisi. And the fact that he's not alone with this assessment is already demonstrated by the star studded exhibitor list 17 months before PaintExpo 2018 opens its doors. Roughly 170 companies from 15 countries have already made firm bookings and secured ideal boothlocations. They include nearly all of the national and international heavyweights from the various exhibition segments.
PaintExpo 2018 with Additional Exhibition Hall With roughly 75,000 square feet, net exhibition floor space already amounts to more than 50% of the level reached at the last event. This extremely strong, early demand for booth floor space illustrates the importance of PaintExpo amongst the suppliers of products and services from the field of industrial coating technology. 'We're of course very pleased that the companies are deciding to book so early, and it provides us with the opportunity of clearing the path for further growth. That's why we've increased exhibition floor space offerings to include an additional hall. This is being very well received by the exhibitors so that we've been able to distribute visitor magnets uniformly throughout all of the halls' reports Jurgen Haufmann, managing director of FairFair GmbH.
Procurement Platform for Future-Oriented Painting and Coating
Worldwide demand for optimised painting and coating solutions speaks infavour of strong further development of PaintExpo where visitor numbers areconcerned as well. 'Regardless of where products need to be painted, usersfrom the various regions around the world are generally placing ever higherdemands on finished goods. In addition to optimised quality andproductivity, this also involves more efficient use of materials andresources, as well as sustainability. Beyond this, ever smaller lot sizesand increasing individualisation necessitate more flexible solutions in thefield of coating technology. New challenges for coating job-shops and companies with in-house painting operations are also resulting from the use of new materials, for example fibrous composite materials for lightweight parts, as well as the use of various materials within a single finished product. 'Thanks to an exhibition programme which is focused exclusively on liquid painting, powder coating and coil coating, as well as market-driven, representative and future-oriented exhibitor offerings, PaintExpo 2018 will be a point of departure for the visitors in their search for suitable solutions based on products and processes', states Jurgen Haufmann with confidence.
The exhibition programme covers liquid painting, powder coating and coil coating systems, application systems and spray guns, liquid paints and powdered enamels, automation and conveyor technology, cleaning and pre-treatment, drying and curing, environmental technology, pneumatics, compressed air supply and exhaust purification, water treatment, recycling and disposal, accessories, measuring and test technology, quality assurance, paint stripping, job-shop coating, services and technical literature. Beyond this, downstream process steps such as printing and packaging are covered as well.
