What is touch screen spraying technology?

Among the numerous anti glare solutions in touch screen manufacturing, spray coating technology has always held an important position due to its unique flexibility. The core advantage of spraying technology lies in its "reversibility". Unlike permanent changes in etching processes, our nanoscale silica suspension can achieve different effects from slight matte to deep anti glare on the same production line by adjusting spray parameters.
 

To overcome the "orange peel" phenomenon that is prone to occur in traditional spraying, our engineers have developed a three-level atomization spraying system. The first stage decomposes the coating into droplets of 30-50 μ m, and the second stage undergoes electrostatic adsorption treatment, ultimately forming a uniform coating under compressed air at 0.3 bar. This system works in a constant temperature curing environment of 25 ℃± 1 ℃ to control the coating thickness deviation within ± 0.2 μ m.
 

It is worth mentioning that our environmentally friendly coating formula has passed RoHS 2.0 certification. While ensuring a hardness level of 3H, the VOC emissions are 40% lower than industry standards. A European elevator panel customer particularly appreciates this process because their products need to meet strict indoor air quality requirements.
 

Despite the attention paid to emerging AR coating technologies, spray coating AG remains the mainstream choice in the cost sensitive education tablet market. Our customized 7% haze solution for a certain brand of student tablets reduces touch screen reflection by 72% in classroom lighting environments, while increasing costs by less than 5%.
