Dupont Asbestos Confession

Philadelphia, PA: The Dupont Corporation's days are likely numbered, after its corporate representative admitted in a New Jersey court that DuPont knew by the 1930s that asbestos could cause health problems, and was aware of its link to lung cancer and asbestos mesothelioma by the 1950s. DuPont used asbestos in its factories and other facilities for decades.

Judith Stadler was named as a representative for the one of the world's largest chemical companies to testify before the court with the purpose of investigating the existence and depth of DuPont's knowledge concerning the dangers of asbestos as well as what it did or did not do to protect workers. Some of the company's internal communications from the 1960s show that DuPont management knew about the risks of asbestos exposure but chose to hide the information from its workers and the public.

Although Dupont did not manufacture asbestos products, it did use materials containing asbestos in its chemical plants for countertops, lab equipment (such as Bunsen burner pads), and protective heat- and chemical-resistant clothing. Attorneys for the plaintiffs estimate that thousands of Dupont employees or employees of contractors could have been exposed to asbestos in the past decades.

As part of a huge class action lawsuit against DuPont Chemical, plaintiffs claim that DuPont management was aware of asbestos dangers as early as 1940, but chose to conceal that information instead of instituting policies that would have protected workers’ health.

Willis Whisnant Jr., who worked at Dupont as a pipefitter in 1966, died from mesothelioma in 1999. After his death, his family joined the class action suit, claiming that DuPont negligently and maliciously exposed workers to asbestos when the company knew asbestos dust and fibers  created health hazards.<more>

Asbestos exposure led to death of Runcorn ICI worker
A MAN who died from asbestos poisoning after working at industrial company ICI had been told his period of exposure was ‘not life threatening’.

An inquest heard on Thursday how Harold Smith, of Halton Lodge, Runcorn was exposed to asbestos throughout his working life, which ultimately led to his death.

Mr Smith began working at ICI Pilkington in 1946 after leaving school. He worked for the company during which time he worked around pipes containing asbestos on a regular basis.

In a life statement read out to the court, Mr Smith recalled working in various plants and factories. Labourers would leave asbestos lying around on the floor and workers would then ‘throw it around like snow balls’.

He would assist the labourers to lag pipes, causing more asbestos to become airborne. <more>

Greenpeace protests DuPont chemical use
The environmental group Greenpeace sent a blimp over Delaware and nearby New Jersey this morning as part of a worldwide campaign to eliminate toxic chemicals.

The blimp was tracing what on-the-ground advocates said was the possible path of hazardous chlorine gas that could spill from DuPont Co. plants nearby.

The blimp, launched by Greenpeace pilots at New Castle Airport, passed over the park and DuPont’s Edge Moor plant, crossed the river, circled DuPont’s Chambers Works and retraced its path.

Greenpeace leaders say the airship was sent to focus public attention on the riverside plants’ hazards and a long-running federal debate over chemical plant safety and disputed proposals that could require use of safer chemicals or processes. <more>

OSHA Issues Data on Chemical Exposure
The Occupational Safety and Health Administration (OSHA) announced the release of 15 years of data providing details of workplace exposure to toxic chemicals.

The data is comprised of measurements taken by OSHA compliance officers during the course of inspections, and includes exposure levels to hazardous chemicals including asbestos, benzene, beryllium, cadmium, lead, nickel, silica, and others.

The data offer insights into the levels of toxic chemicals commonly found in workplaces, as well as insights into how chemical exposure levels to specific chemicals are distributed across industries, geographical areas, and time, OSHA said.

“We believe this information, in the hands of informed, key stakeholders, will ultimately lead to a more robust and focused debate on what still needs to be done to protect workers in all sectors, especially in the chemical industry,” said Assistant Secretary of Labor for OSHA Dr. David Michaels.

With an understanding of these data and their limitations, it can be combined with other related data to target further research into occupational hazards and illness, OSHA said. In addition to the raw data, OSHA said it will soon make available an online search tool allowing public access to the information. <more>

AAMA Encourages Congress to Approve One-Year Delay on EPA's Lead Rule
SCHAUMBURG, ILL. -- The American Architectural Manufacturers Association (AAMA) and its members continue voicing their support to delay implementation of the Environmental Protection Agency's (EPA) Lead: Renovation, Repair and Painting Rule (LRRP). Although the new rule took effect on April 22, government leaders are reviewing legislation introduced on April 29 that would postpone implementation until accreditation classes are held for a period of at least one year.

"It is fair and logical that remodeling contractors need time to gain the proper training and certification so that they can comply with these new requirements," says Janice Charletta, AAMA association services director. "The proposed one-year delay also will give the EPA more time to adequately prepare for full implementation and to fully inform U.S. homeowners of the impending requirements." <more>

DuPont and Tate & Lyle expanding Tennessee bioplastics plant
LOUDON, TENN. (Updated May 5, 4:05 p.m. ET) -- The bioplastics movement continues to roll ahead, with DuPont Co. and Tate & Lyle announcing a 35 percent capacity increase at their Bio-PDO resin plant in Loudon, Tenn., by the middle of 2011.

Construction of the expansion is set to begin next month, officials with Wilmington, Del.-based DuPont and Tate & Lyle of London said in a May 4 news release. The project is expected to create 130 temporary construction jobs and a small number of permanent jobs, according to DuPont spokeswoman Michelle Reardon.

“We had record sales last year and are already anticipating the need for additional capacity after just three years of operation,” DuPont Tate & Lyle Bio Products LLC President Steve Mirshak said in the release. “This expansion is proof that cutting-edge industrial biotechnology can deliver products that meet the needs of industry and consumers while contributing to a smaller environmental footprint.”

DuPont Applied BioSciences President Craig F. Binetti added that the expansion “is an important milestone in how superior performing, cost-effective products, which reduce reliance on fossil fuels, are creating a viable bio-based business.”

Polymet™ Base Coat & Polymet-Seal™ Sealer top Coats:
The base coats can be applied separately or with Sealer top coat combination according to various color and friction requirements. The coating offers Chrome (VI) free surfaces with  Zinc-Aluminum flake based silver grey appearance and meets WEE, RoHS & ELV legislation for not using six declarable substances in coating formulation.
The coating is single pack system which gives easy to use & suitable for various climates and reduces costs of rejection by not having risk of jellifying process. The water based coatings are normally non flammable, Easy water cleanup, Low Odor, Environmental friendly and low Curing temperature compares to other products around 200 deg c. This coating has a ability to recoat and better adhesion with sealer top coats. The sealer top coats are water based thermosetting corslinked system organic or inorganic type with variety of colors like Silver, Black, Blue, Red & White etc. which improves mproves the SST life, UV resistance, resistance to automotive fluids and improves or stabilize the Co-efficient of friction values for threaded parts during assembly.

Aquazinc™-Single coat system:
The Aquazinc is made by -Al. flake, water borne one coat system, Silver grey in appearance. This coating is integrated with lubricants and do not need of additional top coat to adjust the friction values for threaded hardware parts and Fasteners.

Single coating system applied by 2 times or as required by dip spin coating and one coat by Spray. It is economical application due to no change in coating chemical for 2nd coating  cycle. The single coat water based coating is best suitable for Red Rust 240 hours and could be Replacement for Zinc Plating!

Main Characteristics of Polymet™ Zinc flake coating:
The first and important characteristic of Polymet™ coating is higher corrosion protection in comparison with electrolytically deposited zinc or zinc alloys. With uniform application of  coating layer by advanced application techniques, 720 hours SST can be achieved with even lower thickness like 8-10 microns and the coating is very suitable for spring steel and high strength steel parts. Other properties are:

Water soluble: Low VOC
Sacrificial behavior
Heat resistance of 150 deg c by organic and 200 deg by Inorganic sealer top coats.
Free from Hydrogen Embrittelment
Protection of various corrosions
Anti Freezing in cold climates
High Chemical resistance
Improved Wear resistance
Colored sealer top coats for aesthetic and sorting
Possible to adjust the required Co-efficient of friction
No hydrogen Embrittelment stress cracking of high strength metal parts

Modes of Corrosion Protection
There are three primary modes of corrosion protection and high performance protective coatings generally use all three in synergistic combination to achieve superior protection.

Barrier Protection is the simplest form of corrosion protection. An impermeable coating over a corrodible substrate prevents environmental factors from attacking the base metal. Unfortunately, if the coating is damaged, the substrate will begin corroding and the protective coating will lift off along the edges of the damaged area. In addition, no coatings are truly impenetrable; many coatings have a high water transmission rate, allowing water to penetrate through the coating, thus allowing corrosion.

Sacrificial Protection is the application of a ‘sacrificial’ metal (i.e., one that is more active or higher in the electromotive force series) to the substrate. This more active metal then sacrifices itself to protect the less active metal. Thus, for example, zinc, aluminium coatings will protect steel.

Zinc coatings may be applied as components of protective coatings, by electrodeposition, by mechanical deposition, by hot-dip processes, and in many other ways; aluminium, by virtue of its’ reactivity, cannot be commercially applied Electrolytically, but it may be applied in many other ways like non Electrolytically applied dip spin coating techniques.
Inhibitive Protection is the incorporation of an inhibitive agent in the coating. Inhibitive agents prevent corrosion by migrating to the molecular corrosion site and intervening in the corrosion mechanism.

Salt Spray Protection by Polymet™
Because these coatings last for years under environmental conditions, accelerated testing procedures are used to evaluate coatings. The most common test is the ASTM B-117 Salt Spray (or Salt Fog) test. In this test, the parts to be tested are exposed to a mist of 5% sodium chloride at 950 F. When red rust is evident the part is deemed to have failed. While zinc plating or phosphate and oil generally provide protection in the 50 hour to 200 hour range, some of these products are able to achieve protection in excess of 1000 hours of salt spray protection.

Various Corrosion Protections by Polymet™ coatings:
The Polymet™ coating protects substrate from various corrosion forms
listed below:
Group 1 - readily identifiable by ordinary visual examination
Uniform corrosion
Pitting
Crevice corrosion
crevice model
pack rust
Galvanic corrosion
Lamellar corrosion
Group 2 - may require supplementary means of examination

Polymet™
Superior results are achieved when the items to be coated are first degreased (using, preferably, conventional alkaline degreasing - although solvent based processes can also be used) and then blasted with an abrasive such as silica, steel grit, or alumina to achieve a surface profile that provides optimum performance and adhesion. In general, the best performance is achieved when the surface preparation is a ‘white metal blast.’
Oil Cleaning-Degreasing: Environmental friendly Alkaline or Solvent base oil cleaning is recommended to use, It is applicable to all metal parts. Good oil cleaning is also enough as a pre-treatment for some parts. No acid cleaning for parts having 32 HRC or higher hardness and spring steel to avoid hydrogen embrittlement.
Phosphate (as for example, zinc phosphate or iron phosphate) is often used as a surface preparation for coatings; it is inexpensive and relatively foolproof. The primary disadvantage of phosphate coatings is that they are non-conductive. Nearly all high performance protective coatings rely on sacrificial action to achieve a high level of protection; the traditional view is that having a non-conductive intermediate coating interferes with the efficacy of the coating; this view has disappeared somewhat over the past decade or so.
Shot Blasting: For high strength steels (10.9 grade and above or hardness >32 HRC), Shot blasting is preferred, since Phosphate treatment may lead to Hydrogen Embrittlement, so it is not recommended for spring steel and high strength steel.
Application Techniques
Polymet™ Polymet-Seal™ Aquazinc™ products can be applied with non Electrolytically applied Dip Spin coating techniques for mass produced hardware parts and by spray application with or without electrostatic for larger metal parts.
Dip spin coating process whereby product is placed in a mesh basket, submerged in coating solution and spun to remove the excess coating. The temperature and viscosity of the coating, immersion time, spin direction and velocities and the cure method are among the variables that allow users to customize a process recipe and achieve precise, highly repeatable results.
Polymerisation Cycle
The coated parts need to cure at around 200 deg c for polymerisation and cross linking of added polymers before the coating is functional. The SST results and other chemical related properties vary if the baking cycle is not being performed properly.
