3M 3950 Edge Sealer
Edge sealing minimizes the adverse effects of rigorous use or prolonged or severe exposure conditions by providing water and contaminant-tight seal between a graphic film and substrate.
It is required for some 3M warranted graphics (refer to the base film's Product Bulletin for details).
These products also may be applied even after the applied film shows signs of wear, such as edge lifting,to significantly reduce further wear; however, such application does not meet the requirements for warranted graphics.
Edge sealers 3950 and 4150S are single component colorless liquids.
Edge sealer 8914 is a clear tape used to seal vehicle window graphics and for sealing cut edges and seams on watercraft graphics
