Reflective Film for Traffic Signs and Markings

They differ, among other things, in documented retroreflective performance and intended use. The 3M manufacturer document describes High Intensity Prismatic Series 3930 as a microprismatic reflective film in class RA2 C and assigns Diamond Grade DG³ Series 4090 to class RA3 C. Those classes cannot be applied to every reflective film in the range. Check the requirements at the installation location and the data for the specific product version.

No. The range includes 3M Flexible Reflexfolie 823-11i, a flexible, metallised version described specifically for vehicle warning markings. Other listed films are described, for example, for traffic signs. The vehicle surface, contour, service conditions and requirements for the marking matter when choosing a product. Suitability cannot be inferred from the word “self-adhesive” alone.

First establish the selected product and its intended use. We then need the shape, dimensions, substrate and planned processing step. This information helps assess whether a cut piece or die-cut part supports the required marking and how it should be supplied. Retroreflective performance comes from the film and its product construction; converting does not create a higher reflection class.

State the function of the marking, the location, substrate and required geometry. If a particular retroreflection class or product series is specified, include that information and the applicable requirements for your use. For the delivery format, indicate whether you need a roll, cut piece or die-cut part. Krückemeyer GmbH can then assess the product and processing with you.
