Guidelines for Automotive and Architectural Applied Window Film
Automotive Visual Inspection Guideline
Installed automotive film on glass surfaces is not expected to have the same level of visual quality as glass. The following criteria apply to the installed film only and not to any defect inherent in the glass.
Installed film normally has a slightly delayed time for full adhesion to be achieved since installation utilizes a surfactant or slip agent solution in water to float the film onto the glass: the excess water is then squeegeed out, but inevitably some residual water will remain between the film and glass.
Architectural Visual Inspection Guideline
Installed film on flat glass surfaces is not expected to have the same level of visual quality as glass. The following criteria apply to the installed film only and not to any defect inherent in the glass.
Installed film has a discrete time for full adhesion to be effected since installation utilizes a detergent solution in the water to float the film onto the glass: the excess water is squeegeed out, but inevitably residual water will remain between the film and glass.
