Johnson glass film in the United States uses magnetron sputtering coating process to deposit rare metals and compounds on the substrate, which has a strong control effect on sunlight. DPS quick-drying pressure sensitive adhesive is developed by Johnson Glass Film company in the United States on the basis of traditional PS adhesive. By adding quick-curing ingredients, the drying time is shortened to 3 hours, and the window can be easily rolled down after 3 hours of film pasting.
Johnson film is a kind of self-adhesive polyester film that can be attached to the glass surface. It is mainly composed of polyester substrate, adhesive, composite layer and lining. Used for sunlight control and safety protection.
Johnson glass film in the United States deposited a dense nano-carbon layer on the surface of the metal film coating, and developed a composite film, which maintained the high thermal insulation performance of the metal film and also had the low visible light reflectivity of the nonmetal film.
Technical features:
1, no interference signal
Using the global patent technology-TIN magnetron sputtering technology, an IR ceramic thermal insulation film was developed, which did not produce signal shielding and put an end to the problem that traditional metal films interfered with mobile phones and GPS wireless signals.
2. Matrix
The polyester substrate with excellent optical and physical properties is adopted. The thickness of this material is only a few tens of microns, but its strength and toughness are super strong, and it still maintains excellent stability under different temperature, humidity and harsh natural conditions.
3.CST wear-resistant and scratch-resistant coating
All products of Johnson & Johnson glass film in the United States have a hard scratch-resistant coating-CST coating, which is made of high-quality oligomer and acrylic acid by patented technology.
Through laboratory tests and thousands of field applications, it is proved that CST coating exceeds the American ASTMD 1044-94 standard, which can provide lasting scratch and wear protection for diaphragm and ensure the long life of automobile film.
