Traditionally Auto parts industry is the mainstream of the electrophoretic paint application market, all dip coating things is one of the important internal parts for assembling cars, the special anti-corrosion requirements on its edge is self-evident, imagine a car will accompany his master up to ten years, twenty years or more , if there is no high strength, how you could go to the end!
It is for this reason that HLS constantly pursues the ultimate perfection and creates our high-edge anticorrosive cathodic electrophoretic coating. It is also the star product series of HLS that we are proud of. It has passed the access qualification of many automobile OEM in the world, such as Volkswagen, GM and Ford.
In order to effectively improve the corrosion resistance of automobile parts, especially the edge corrosion resistance, we introduce silicon polymer components and flake anti-corrosion filler into the coating resin to improve the wet adhesion between the coating film and various substrates, effectively shield the corrosive medium, delay the corrosion speed, and improve the corrosion resistance of the coating film.
At the same time, special rheological auxiliaries were added to control the flow state of the coating film and inhibit the shrinkage of the electrophoretic coating in the process of baking and curing, so as to increase the thickness and coverage of the coating film on the edge of the workpiece and meet the requirements of anti-corrosion performance of vehicles.
HLS-17 series products have been recognized by many domestic and foreign auto parts manufacturers for its Ultra salt spray resistance performance. The measured data obtained on site shows that it can not only meet the requirements of 1200 hours neutral salt spray resistance, but also meet the Cyclic corrosion alternating requirements of Volkswagen, Mercedes, Ford, Volvo and GM
Other physical and chemical performance indicators are in the forefront of the industry.
Excellent corrosion resistance
HLS-17 series of products adjust the curing rheological properties of the film through the introduction of hyperbranched super molecular weight resin components, effectively improve the film edge coverage, the film has excellent edge protection performance.
Excellent edge protection performance (blade)
With the higher and higher requirements for anti-corrosion performance, the edge protection performance of the sharp metal workpiece is also increased, the standard blade is used for testing, the film thickness is 20-22μm, the thinnest place of the blade is 9-10μm, the neutral salt spray test for 240h, blade edge no rust, with excellent edge protection performance, Fully meet the market requirements of the workpiece edge protection performance.
Neutral salt spray resistance test
HLS-17 series products have good compatibility with environmental protection skin film pretreatment and phosphating skin film pretreatment, and excellent corrosion resistance. The thickness of electrophoretic coating film was 20-22μm and the neutral salt was tested for 1200h. The single side corrosion width of the coating film was less than 2.0mm, and there was no obvious blister and rust on the surface of the board, and the edge protection was also very excellent
Cyclic alternating experiment
As anti-corrosion performance requirements higher and higher, anti-corrosion test of single condition has been not adapted to the most automobile OEM, cyclic corrosion alternating can simulate different natural weather conditions, high-end mainstream technical requirements, HLS-17 series of products can satisfy Volkswagen circulation corrosion alternating 60 cycle test, not only in a leading position in domestic brand paint, it is also competitive if comparing with many international first-line coatings brand
HIGH THROWING POWRER
HLS-17 series of products have the characteristics of high throwing power, which can meet the requirements of the complex structure of auto parts inside the film, the penetration force of four boxes experiment can reach more than 60%, not only ensure the effective film forming parts, but also improve the utilization rate and production efficiency of the coating.
LOW CURING TEMPERATURE
When electrophoretic coating, the film drying link ensures the best performance of the film after curing, and is also the main link of high energy consumption and high emissions. HLS-17 series of products with 160℃/20min curing level, efficient energy saving and emission reduction, it is in the leading position of the automotive parts coating industry.
Super anti-rust performance
Edge anti-corrosion outstanding, has reached or even surpassed the industry level
Have good plate adaptability, suitable for all kinds of hot and cold rolled plate and galvanized steel plate
HLS-17 series products are suitable for the industry with high anticorrosion requirements, with excellent edge anticorrosion performance, widely used in automobile chassis parts, seats, rolls, casting parts and other high anti-corrosion fields.
