Trosifol® UV Extra Protect
Invisible to the human eye, ultraviolet (UV) light is as vital as it is hazardous. While a certain degree of exposure is beneficial, too much of this part of the spectrum of natural sunlight is harmful. Excessive exposure to UV light in the 315 to 400 nm range is particularly damaging to the human skin – and no less so to plastics, pigments and paints.
Conventional window glass is impermeable to UV light below 320 nm. PVB films between glass plies filter out further UV light. Trosifol® UV Extra Protect is a PVB film that blocks out incidental UV light in its entirety.
