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.

Limitations of End Uses The solvent in the edge sealer may attack certain painted surfaces; always test in an

inconspicuous area before using.
