·Stock vehicle storage security risk general dealer claim
According to the US Detroit News Network on June 3, a General Motors dealer in Arkansas, USA, filed a claim with GM because of the "high security risk" of its GM. These stock vehicles also include vehicles other than those affected by the general ignition switch recall event. On May 23, the Nettleton car sales company filed a lawsuit against General Motors on behalf of GM's other car dealers in the federal court in Little Rock, Arkansas, asking GM to make genuinely punitive damages. On Monday, GM disclosed the news in a bankruptcy court in Manhattan. Nettleton said that before this year, GM had been deliberately concealing the defects of its ignition switch. General Motors, based in Detroit, has recalled 2.59 million problem cars and replaced the ignition switch. Prior to this, 13 people died as a result of this defect. A defect in its ignition switch shuts off engine power and prevents the airbag from opening. “The plaintiff believes that some of the GMs that were affected by the recall also have the same or similar ignition switch problems as the recalled vehicles.†For the recall list, Nettleton said. According to the plaintiff's lawsuit, there will be other general vehicles will be added to the vehicle compensation list.
Powder coating is a dry finishing process that has become extremely popular. Powder coating is used on a wide array of products. More and more companies specify powder coatings for a high-quality, durable finish, allowing for maximized production, improved efficiencies, and simplified environmental compliance. Used as functional (protective) and decorative finishes, powder coatings are available in an almost limitless range of colors and textures, and technological advancements have resulted in excellent performance properties.
Advantages over other coating processes
1. Environment friendly. Powder coatings contain no solvents and release little or no amount of volatile organic compounds (VOC) into the atmosphere.
2. More thicker coatings without running or sagging than conventional liquid coatings.
3. Perfect color consistency. Powder coated items generally have fewer appearance differences than liquid coated items between horizontally coated surfaces and vertically coated surfaces.
4. A wide range of speciality effects are easily accomplished using powder coatings that would be impossible to achieve with other coating processes.
5. Curing time is significantly faster with powder coatings compared to liquid coatings especially when using ultraviolet cured powder coatings or advanced low bake thermosetting powders.
Powder Coating Process
The Powder coating process involves three basic steps: raw material preparation or the pre-treatment, the powder coating application and curing.
Powder Coating Substrate Considerations
Before applying the powder coating material, you must first consider the substrate material that you will be coating. It is very important to have a clear understanding of the true composition of the surface of the part.
ALUMINUM:
ALUMINUM CASTING
COLD/HOT ROLLED STEEL
CAST IRON
BRASS
COPPER
ZINC
STAINLESS STEEL

Damp heat test GB/T 1740-1979 >1000 hours,
mild loss of gloss
Temperature resistance 100°C/48 hours, excellent gloss retention
Powder Coating Colours
RALAL Range, Pantone Range, and other Natural Colour Systems (NCS)
If you have a Powder Coating Colour requirement that we do not stock we are usually able to source powders from the above ranges within 48 hours.
Powder Coating Gloss Level
Gloss is measured as a percentage.
1. Matt Powders are between 20% and 30% gloss.
2. Semi-gloss Powders are usually around 60-65% gloss.
3. Gloss Powders at least 80% and can be 85%.
Powder Coating finishes
1. Textured Powder Coating:
2. Ripple/Leatherette Powder Coating.
3. Hammerite Finish Powder Coating.
4. High Temperature Powder Coating.
5. Anti-Bacterial Powder Coating.
6. Clear or Tinted Powder Coatings.
Application Field
1. In automotive applications:
a) some primers used on bodywork have converted to powder. This has given improved coating quality and provided ecological advantages.
b) where a functional as well as a decorative finish is desirable powder coatings are being used increasingly eg.
i. - wheels,
ii. - bumper bars,
iii. - mirror frames,
iv. - oil filters,
v. - battery trays,
vi. - coil springs and
vii. - heads.
2. Appliances
a) Specially formulated, hard and scratch resistant powder coatings are replacing the energy-intensive porcelain finishes on washer tops and lids.
b) Powder coatings are being used on range housings, freezer cabinets, drier drums, and microwave oven cavities.
c) Outdoor furniture, farm and garden implements and garden tractors also are being finished with powder coating materials. - Interior fluorescent light reflectors are coated using a highly reflective, very thin powder coating.
d) Exterior lamp housings on highway and parking deck fixtures are coated with specially formulated powder which give ultra violet light protection and added corrosion protection
