Powder coatings are widely used in automotive components

Powder coatings in automotive parts applications, started in the mid-1970s, such as hanging parts, engine blanks, oil filters, air purifiers and brake tubes and other components, the preferred variety is epoxy powder coatings; Powder coatings for exterior metal components such as door and window components, wipers, luggage racks, bumpers, etc., with polyester or acrylic as the preferred system. These powder coatings are usually low gloss black or dark gray products. Epoxy powder coatings give coatings excellent adhesion, regenerative properties, stone resistance, chemical resistance and corrosion resistance, which can be achieved after 15min curing at low temperatures (130 degrees C). For coating parts under the hood to meet the requirements of use in extreme environments. After sand blasting rust cast iron engine body directly with epoxy powder coating, with short-wave infrared rapid curing (160 degrees C, 8min), and then the cylinder head surface and other key parts of the machining, to achieve micron-grade tolerance, to obtain a surface suitable for gasket positioning, coating requirements can withstand high-speed mechanical processing, no debris, roll layer or surrounding fins and other defects. The world-class automotive manufacturers MITUBISHI, KIA, FORD, CHRYSLER, BMW, RENAULT and VVV all use these technologies, and the representative brand name of the powder coating is INTERPONAUTOBLOCK. Components such as oil filters and brake tubes, coated with INTERPONAUTOPAN powder coating, inserted filter paper and then bent around the base of the filter oil filter components to complete assembly, the main performance requirements are oil resistance. Polyester powder coatings and acrylic powder coatings have good weather resistance. Almost all external metal components can be coated with powder, roof fences, doors and windows components are typical exterior trims, color is usually black flat light or dark gray, requiring excellent UV aging resistance and aesthetics, this part of the coating accounted for almost 15% of automotive powder coatings.external durability can be measured by an instrument, such as a drop in mirror gloss or color, usually in conjunction with visual standards such as "greyscale color labels". Most of the current technical standards for exterior trims require up to 12 months of Exposure to Florida. For example, Ford Motor Company requires AATCC grayscaness color label 4 (WSKM2P141). Now, some car manufacturers have recognized that exterior trims need to meet the same high-quality weather resistance as body housings, as typically, when General Motors (GM) requires 60 months of Florida exposure (GM4367M) for coating performance, a level known as "advanced durability." Most polyester powder coatings meet the performance standards of the standard durability specifications for external metal components, as is the case with INTERPONAUTOBODY powder coatings. "Advanced durability" is usually achieved with acrylic powder coatings.according to experts, however, recently proved to be the name of THEOPONAUTOBODY5000, a new class of polyester powder coating in Florida exposure for more than 60 months, the preservation rate is greater than 80%, compared with acrylic system, the cost is lower, There is no general acrylic powder in use prone to powder incompatible compatible problems, its shoals have been tracked in Europe, and has been used by TOYOTA, HONDA, AUDI, PSA, FORD and TAGUAR car companies manufacturers. In addition to improved weather resistance, polyester powders are also improved in aesthetics, with a coating of 20. With a gloss of more than 90 and an image clarity value (HUNTERDORIGON definition) of 85, it can have a look similar to traditional solvent-based coatings and multi-vehicle body housing paints.
