The International Window Film Association is the world's leading window film manufacturer, and the industry standards set by it represent the highest quality and technical standards in the world. The members of the association are the leading window film manufacturers in the industry, and Alan Johnson, the founder of Johnson & Johnson Glass Film, is the founder of the International Window Film Association.
 
不少用户会将强生与生产医疗卫生保健品的Johnson & Johnson混淆，这是两家完全不同的公司，强生全称Johnson Window Films，是专业从事玻璃膜生产的制造商，拥有上百项专利。强生于1996年进入中国市场，中国中材东方国际贸易有限公司是强生中国唯一总代理。
 
A thin layer of window film is generally composed of 7-8 layers of different layers, and high-grade magnetron sputtering film often has 9-10 layers, and the more layers there are, the better the thermal insulation performance. Due to the differences between the films produced by different processes, solar films generally consist of an anti-stick film, mounting adhesive, polyester film, a metal or ceramic layer, and a wear-resistant layer.
 
Polyester film is the base layer of window film, which must have the function of being very tear-resistant and anti-breakdown, in the selection of substrates, Johnson & Johnson generally chooses polyester substrates produced by DuPont, which have good performance in light transmission and clarity. Because the titanium nitride material is thin enough to transmit light to a certain extent, Johnson & Johnson's high-end window films all use titanium nitride nano-ceramic magnetron sputtering process, which can use the principle of electric field and magnetic field to evenly sputter titanium nitride particles on the high-tensile polyester substrate with high speed and high strength.
 
The outer layer of the window film needs to have a certain hardness and scratch resistance to avoid being scratched in daily use, causing blurred vision. In terms of scratch resistance, Johnson & Johnson film has outstanding performance, with a number of anti-scratch layer patents, as well as anti-climate abrupt change treatment technology and pressure-sensitive electromagnetic treatment technology that are superior to the industry labeling, which can obtain good anti-wear and anti-scratch effects.
 
Johnson & Johnson film is very cost-effective, and high light transmittance in the front gear is the main feature of its products. Johnson & Johnson's products are mostly manufactured by titanium nitride nano-ceramic magnetron sputtering process, and many series use titanium nitride front gear and metal side and rear gear combinations to provide cost-effective solutions. Field, LinkedIn and Swift series is Johnson & Johnson's whole car using titanium nitride magnetron sputtering window film series, its front visible light transmittance between 80%-85%, infrared blocking rate of 63%, 84% and 65%, performance is acceptable, and dragon film, Weigu and other top brands produced by the top brands, its infrared blocking rate can reach more than 90%, however, if the pursuit of high light transmittance, Johnson film is the most suitable product.
