Between the colorful backshells of smartphones and the technological cockpits of new-energy vehicles, the colorful colors of children's toys and the metallic luster of cosmetic bottles, there is a key technology to support modern industrial aesthetics - plastic coatings. This seemingly traditional chemical field is quietly expanding at a compound annual growth rate of 9.2, driven by environmental regulations and consumer upgrades, opening the evolutionary journey from “functional coatings” to “intelligent interfaces”.

Plastic coating technology breakthroughs are rewriting the industry rules of the game. In a laboratory in Zhejiang, researchers through the molecular structure modification technology, successfully developed a two-component waterborne polyurethane system, so that the PP substrate 100 grid test adhesion to ASTM D3359 standard grade. This innovation not only cuts VOCs emissions to below 50g/L, but also realizes a balance between coating hardness and flexibility. What is more noteworthy is that the new electromagnetic coating applied to 5G equipment adopts the synergistic technology of grade aluminum silver powder and carbon fiber, and its performance breaks through 35dB under the high frequency band of 10GHz, so as to construct a protective net for the intelligent terminal.

The differentiation of market demand has given rise to the blossoming of technology routes. The pursuit of touch and function in the automotive field has driven the development of micro-texture tactile coating technology, which realizes the unity of skin-like feel and anti-fingerprint performance by controlling the surface roughness Ra value in the range of 0.8-1.2μm. In the toy industry, the environmental protection system that passes the EN71-3:2019 migration test has become the entry threshold. The bio-based acrylic liquid developed by a Guangdong enterprise not only controls the heavy metal content to less than 1/10 of the detection limit, but also realizes the anti-bacterial effect for up to 12 months by virtue of the microcapsule slow-release technology. In the field of cosmetic packaging, the combination of PVD coating and UV curing technology makes plastic parts show a mirror effect comparable to metal anodizing, but the cost is 40% lower than the traditional process.

Environmental certification system is the industry competition pattern. With the implementation of the EU REACH Annex XVII new amendments, domestic plastic coating enterprises set off a wave of green technology research. A company in Jiangsu developed a low-temperature curing system, the baking temperature from 120 ° C to 60 ° C, with the use of bio-based curing agent, so that a single product carbon emissions reduced by 65. This innovation not only allows products to obtain the EPD Environmental Product Declaration certification, but also to help downstream customers to pass the review of the automotive industry's IMDS substance declaration. On the testing side, the application of intelligent quality control system has shortened the response time of heavy metal detection to 30 seconds, and the ΔE control precision of online colorimeter has reached 0.3. These technological advances are pushing the industry's entry barrier to new heights.

The synergistic effect of material innovation and process is becoming more and more prominent. The introduction of Shandong Silver Arrow ultra-low-odor aluminum silver paste solved the problem of flow marks in the injection molding process, and its unique lamellar structure increased the orientation of metallic pigments by 20, with the L-value (brightness) reaching a new industry high of 92.5. In the field of 3C electronics, the addition of a new type of thermally conductive filler makes the thermal conductivity of the coating break through 2W/m-K, which, together with the 5μm ultra-thin coating process, provides a reliable heat dissipation solution for folding-screen cell phones. What is more worth looking forward to is that the R & D breakthrough of flexible OLED substrate coating, so that the plastic display's bending resistance breaks through 200,000 times, this technology may open up a new situation in the form of consumer electronics.At present, the plastic coating industry is standing in the key node of transformation and upgrading. Water-based technology routes through the rate of 12 per year to climb, radiation curing system in the market share exceeded 18, behind these data is worth hundreds of billions of market reconstruction. For enterprises to grasp the automotive intelligent surface, biomedical coatings, new display materials, three major tracks, may be able to seize the first opportunity in the industry changes. When the environmental standards and aesthetic needs to form a synergy, plastic coatings this industry, is writing their own times answer sheet.
