3M™ Scotch-Weld™ Preformed Sealant Strip 5313 is a tacky solid extrusion based on a synthetic rubber. The adhesive strength of 5313 is sufficient to cause cohesive failure of the sealer before loss of adhesion to the substrate, when pulled in tension.3M™ Scotch-Weld™ Preformed Sealant Strip 5313 is a non-curing type and retains the same properties and consistency after aging in several different environments, including weathering.
