DM6500 HIGH INTENSITY PRISMATIC GRADE are weatherproof, self-adhesive retroreflective films with an excellent corrosion and solvent resistance.The retroreflective system consists of sealed cells of air backed microprisms, using total internal reflection(see the structure drawing as below).The smooth surface PMMA shows a high scratch resistance and impact strength, and a very good printability with the internal PMMA microprismatic layer.
The reflective data and colours comply with
specifications of this class (RA2; design C)
such as DIN 65720 & DIN 6171 and typeIII
