PMA anti-radiation coating which is invented by PMA group is the only high-tech water-based painting product that using absorbing technology. It is obtained national invention patent, and filled this technology area gap in domestic. It’s made by special ferrite absorbing materials and dozens of rare elements. It has features of wide frequency range absorbing and strongly decay rate. It could absorb electromagnetic wave from 1.0 to 20,000MHZ. According to different coating thickness, it can waken electromagnetic wave 2-20db, and decay rate could reach to 99%. At present, this technology is only owned by America and few other developed countries, it’s the international top technique to protect from electromagnetic pollution. Since it launches market, it’s attracted many large network rooms and building industry. What’s more? This special coating has been recognized by many governments anti-radiation tenders project.
