3M Scotchlite photoelectric grade smooth surface sheeting 7590 is a sealed, water tolerant, printable reflective lens in tape roll form with an acrylic adhesive and liner. Luminance 200X. 3M Scotchlite photoelectric grade sheeting 7590 is a durable, flexible, wide angle, smooth surface, retroreflective sheeting, specially designed for use in photoelectric applications such as retroreflective labels or marks. The sheeting consists of special lens elements enclosed within a transparent resin, having a smooth flat outer surface and is supplied with a low temperature, pressure sensitive adhesive protected by a removable liner. 3M Scotchlite photoelectric grade smooth surface sheeting 7590 is designed for use as expendable code marks in automatic warehouse or conveyor operations. 3M Scotchlite photoelectric grade smooth surface sheeting 7590 is designed for strong uniform response of photoelectric devices up to 45 deg entrance angle. Among the industries it can be utilized are transportation, aerospace, automotive, commercial vehicle, RV, bus, truck, ship yards,-military, metal working, furniture, electronics, solar, trailer manufacturing and woodworking. This tape affords exceptional contrast with its background for increased accuracy, reliability and depth of field in photoelectric sorting and classification systems. This tape is designed to perform at high temperatures. It can withstand continuous exposure to temperatures as high as 200 deg F and short term exposure up to 400 deg F. It provides a typical luminance factor of 200X at -4 deg F reading. Application may be made at temperatures as low as 10 deg F to a clean and dry surface. The sheeting will remain serviceable for many years when properly applied to a suitable substrate and used in typical indoor or outdoor environments.
