Series 3930 prismatic sheeting with pressure sensitive adhesive is a reflective sheeting with a unique construction providing high levels of retroreflectivity for multiple traffic situations. Series 3930 sheeting outperforms its competitors with long-term reflectivity and durability while achieving excellent life cycle costs. Exceeds ASTM D 4956 Spec Type III and IV.Series 3930 sheeting outperforms its competitors with long-term reflectivity and durability while achieving excellent life cycle costs. Exceeds ASTM D 4956 Spec Type III and IV. Not only is 3M high intensity prismatic sheeting bright and durable, it’s better for the environment. The manufacturing process for prismatic sheeting reduces VOC emissions by 97 percent and energy consumption by 72 percent compared to standard engineer grade.
