Protecting human life and fortune from trespass
Trespass through glass is mainly done by using weak window. However if safety
Film is applied; trespass is not possible by breaking glass because this glass cannot be broken by fairly much impact.
Protecting harmful ultraviolet rays
It prevents decoloration or discoloration of high-quality interiors and electronics appliances by blocking harmful infrared rays in sunlight.
Energy saving effect
It prevents transmittance of infrared rays in sunlight and maintains cool temperature.
Therefore it has keeping warm effect.
1. Sputtering technology is more complicated. Sputtering is also done in a vacuum chamber, but the metalizing is achieved at the atomic level. In brief, electromagnetic fields direct streams of ions from a chemically inert gas (usually argon) toward the metal. This ion bombardment, which is often described as “atomic billiards,” causes groups of atoms to dislodge in small bursts and scatter uniformly across the film.
The practical benefits of sputtering are that 25 to 30 different metals can be used and the metalized coating is much lighter. It’s possible to sputter metal in a layer one-hundredth the thickness of a human hair. Different metals are chosen to subtract specific bands of radiation from the solar spectrum. The result is a highly reflective layer with very little mirror effect, heat absorption or color shift. Because sputtering is more expensive, these films occupy the high end of the price range. Metallic films control radiation through reflectivity. Simplified film consists of polyester layers, metallic coating, adhesive and scratch-resistant coatings.
While the performance characteristics of dyed and metallic films are generally distinct, there is some overlap. Heat-absorbing dyed films are somewhat reflective, and metallic films do absorb some heat because of the mass and color of the metals involved.
2. Sputtered window film
Sputtering is the most complicated procedure for creating window film. This process is also carried out in a vacuum but the metallization in this process is achieved at atomic level. Electromagnetic fields direct streams of ions from a chemically inert gas (usually Argon) towards the metal. This ion bombardment (often referred to as “atomic billiards”) causes groups of atoms to dislodge in small bursts and scatter uniformly across the film.
The benefits of sputtering are that around 30 different types of metals can be used; various metals can be chosen to subtract specific radiation from the solar spectrum. The metallized coating is much lighter; a sputtered metal can be created in a layer one-hundredth of the thickness of a human hair.
The result of sputtering is a highly reflective layer that has very little mirrored effect, heat absorption or colour shift and as such warranties are usually 10 years to lifetime. Sputtering is the most expensive process to achieve and as such sputtered window film is at the higher end of price range.
