In the past ten years, under the influence of auto parts suppliers, the auto industry has also adopted UV LED curing technology. The current application of UV LED curing technology in the automotive industry mainly involves: automotive headlight lenses, reflectors, seat belts, center consoles, instrument panels, car interior wooden decorations, instrument panels, screen printing on measuring instruments, cylinder heads Part gaskets, steering wheels, adhesives for sound insulation pads, dark box parts, brake linings, clutch pads, wheels and windows, etc. The above mentioned are not all the application parts of UV LED curing technology in the automotive industry, but also include some three-dimensional objects and some parts outside the car. UV LED light curing of car headlight lens varnish because polycarbonate lens has high elasticity, is easy to design and light weight, it replaced the traditional glass lens many years ago. However, polycarbonate has poor wear resistance and yellowing, so varnish must be applied to its surface during use. The UV LED curing coating just meets this demand, such as high hardness, chemical resistance, and light resistance. Compared with traditional thermal curing, UV LED curing technology has many advantages, such as greatly reducing the processing time, reducing the footprint of the equipment, and increasing the anti-fouling ability of the coating film and the substrate during curing. The car headlight lens coating curing system has achieved a successful breakthrough in the application of this technology to the exterior parts of the car.
