AR coating is a special surface treatment process, the principle of which is to coat one or both sides of the substrate, which can be PET, PC, PMMA, PC/PMMA alloy, etc., so as to make it have a lower reflective ratio, so that the reflectivity of the light is reduced to less than 5%, the common AR coating processing methods are as follows: spraying, roller coating, lifting, magnetron sputtering, vacuum evaporation, chemical etching, of which Magnetron sputtering and vacuum evaporation are the most widely used in optical thin film. Magnetron sputtering and thermal evaporation composite coating technology with uniform coating, close to zero color, and high transmittance occupies a dominant position in the country, but its high demand for resources and high cost also limit its wider application.

Japan Nagase adopts the leading coating stacking technology on PC/PMMA substrate, using the coating method to develop a new optical film products, the reflection transmittance of more than 98%, pencil hardness of 4H, 500g wool felt wiping 5,000 times, zero color, with magnetron sputtering AR coating than the product is not only more excellent performance, but also environmentally friendly, cost-controllable, and to meet the application needs of more industries. Application Requirements. In Japan, this product has gradually matured and occupied the market, and the domestic change of technology is still in a necklace state, many companies also continue to pay attention to the domestic technology upgrading, and hope that there are fine chemical companies can put forward the relevant program. Winlight and its partners, in response to the market demand, adopted its own technology platform, using coated AR coating transmittance enhancement fluid, using multi-layer coating functional coating process, AR anti-reflective to achieve PC/PMMA substrate transmittance 98.5-99%, hardness of 4H, wear-resistant adjustable, the product hydrophobic and oleophobic, not only environmentally friendly, compared with the magnetron sputtering, the cost of a more advantageous, the automotive center-controlled film and other More design possibilities for automotive center control film and other optical film applications.

Coatable AR transmittance enhancer for optical films is not only environmentally friendly and cost effective, but also has the following features:

● Visible light transmittance peaks at 99%, and the average visible light transmittance exceeds 95%, which significantly improves the original brightness of LCDs and PDPs and reduces energy consumption.

Average reflectivity is less than 4%, with the lowest value less than 1%.

●Effectively weaken the defect of whitening of the screen due to the strong light from behind, and enjoy clearer image quality.

●Ultraviolet-resistant to protect your eyes The transmittance rate of ultraviolet light in the spectral region is greatly reduced, effectively blocking ultraviolet rays from harming your eyes.

● More vivid colors and stronger contrast, making the image color contrast stronger and the scene clearer.

●The best anti-scratch and abrasion resistance, the hardness can be adjusted 4H (general PC board hardness is about HB).

●Can be wiped by wool felt or flannel for 5000 times, and the film layer will not be damaged.
