1 Description
3M™ Stamark™ Pavement Marking Tape Series 270 ES (“Tape”) is a retroreflective patterned polymer pavement
marking that can be used as an inlay marking on new asphalt or as an overlay marking on asphalt and concrete
pavement surfaces in good condition.
The Tape offers “Extended Season” applications due to an improved pressure sensitive adhesive (PSA) package on
the bottom surface.
The Tape does not require 3M Stamark Surface Preparation Adhesive P-50 (“P-50”) or 3M Stamark Low VOC
Surface Preparation Adhesive SPA60 (“SPA60”) prior to application, if applied during the application season as
outlined in the 3M Climate Guide for 3M Stamark Pavement Marking Tapes
Series A270 ES: No liner. Used for lane lines, edge lines, channelizing lines, gore markings, stop bars, and
crosswalks.
.
Series L270 ES: With liner. Used to cut symbols and legends.
Series SMS-L270 ES: With liner. Precut symbols and legends.

2.2 Color
The daytime and nighttime colors of Tape conform to ASTM D6628, the Standard Specification for Color of
Pavement Marking Materials.
2.3 Skid Resistance
The patterned, retroreflective, pliant polymer surfaces of Tape shall provide average initial skid resistance
values of 45 BPN or more when tested according to ASTM E303, subject to the following modification:
o Skid resistance is calculated as the average of two measurements taken at an angle of 45° from one
another.
2.4 Patchability
Snow removal equipment and heavy traffic may cause wear and damage to Tape. Such damaged areas can be
repaired using patches made of Tape. Remove damaged Tape and replace it according to the instructions
presented in the “Overlay Applications” section of 3M Information Folder 5.7
