3M™ Stamark™ A380ESD is a high performance road marking tape with long-term retained retro-reflectivity, skid resistance and durable whiteness. Abrasion resistant ceramic beads and anti-skid particles are bonded in a highly durable polyurethane topcoat, to create a tape that provides superior visibility and safety during wet weather conditions.
APPLICATION
The 3M™ Stamark™ A380ESD tape can be used on most road surfaces and is particularly suited to long line applications. Application to dry road surfaces is by overlay using a primer or it can be inlayed onto hot asphalt surfaces. The tape is easy to handle and can be cut to length using a knife or mechanical cutter.
Stamark A380ESD offers “Extended Season” applications due to an improved pressure sensitive adhesive (PSA) package on the bottom surface. Stamark A380ESD requires 3M™ Stamark™ Surface Preparation Adhesive P-50 prior to application.
For rough surfaces, a bitumen plus application is recommended whereby a layer of bitumen is screeded onto the road surface prior to the application of the Stamark tape.
