Before the film must see how selected films

Experts advise , not freeloaders choose low or fake car explosion-proof membrane products , poor membrane structure is simple, this film is less than a year getting a light color will affect the line of sight , will gradually lose the car looks beautiful . If the front windshield using inferior car film , it will affect the driver judgment, causing an accident. Proof membrane can judge the merits of the following aspects .
A hand touch . Quality thick film feels a sense of smooth , low-quality thin film is very soft , the lack of sufficient toughness , and easy to wrinkle.
Second, the nose smell . Inferior film layer residual solvent benzene content, smell, would seriously endanger the health of the owner .
Third, the sharp eyes . Look perspective , clarity , quality and clarity of proof membrane can be up to 90% , and no matter the color depth , perspective properties are good at night , driving rain can maintain a good line of sight. The poor quality of the film used is common dyeing process , relying on the color heat , so dark colors , always looking out the car hazy feeling.
Fourth, biting . Nibble at the film with the teeth , if the bite point of the transparent , colored adhesive films are described , and instead of using the sputtered metal body colored dye penetration method , bulk infiltration method is not the case for .
Fifth, look at quality assurance. Only to have the film manufacturer warranty card is trusted manufacturers warranty card usually contains warranty item, age, payment methods, and the real name of the manufacturer can find the address and telephone number.
Six , on the back of the film to see if there is security signs. Explosion on the back of regular brand film printed with security signs.
Seven, alcohol , gasoline rub. Because the plastic film is a poor membrane staining , the wiping layer after removal of the resist film can see the color to fade. You can also uncover a transparent layer film on the back of the car , plan what with a hard object , fade inferior film is more serious.
Eight , the technical parameters provided by the manufacturer reference : transparency , shininess , insulation . Usually more transparent membrane , insulation will be lower ; more reflective film , the higher the insulation . High transmittance , low and reflective insulation film is a film and good quality .
Nine test insulation. The use of high-powered incandescent simulated solar light, heat test membrane blocking ability . Quality proof membrane insulation rate should reach 80% , inferior film insulation is low, the feeling of sitting in the car will be boring , but it is poor across the ultraviolet , serve to protect the items inside the car and the passenger effect.
X. scratch is a basic performance automotive film. In normal high- lift window membrane , the membrane surface is not scratched, and the film is inferior in this respect the automobile obvious defects .
