Edge Sealer 3950 and 4150S
Edge Sealer Tape 8914
Product Description 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.
Recommended Types of
Graphics and End Uses
Refer to the base film or flexible substrate’s Product Bulletin for details on specific
constructions and any warranty that may apply when using this product.
Limitations of End Uses The solvent in the edge sealer may attack certain painted surfaces; always test in an
inconspicuous area before using.

Prepare the Graphic for
Edge Sealing
1. Do not apply edge sealer unless the temperature is above the minimum recommended
temperature.
2. Remove any application tape and re-squeegee the edges before applying the edge
sealer.
3. Make sure all edges to be sealed are clean, dry and free of contaminants.
Prepare Edge Sealer 3950
or 4150S for Use
To preserve the unused portion of the edge sealer, transfer the desired amount into a
separate disposable container and tightly recap the original container immediately. Leaving
the original container open allows air to contaminate, reducing future shelf life.
Applying a Liquid Edge
Sealer
1. Do not thin the sealer.
2. Use the dauber supplied with edge sealer or a 1/4 inch (0.6 cm) brush.
3. Wipe any excess edge sealer off the dauber or brush.
4. Hold the brush or the flat edge of the dauber so that it straddles the film and substrate
5. Pull the dauber or brush along the edge in a smooth, continuous motion. Make sure
the entire edge is covered with no gaps. See FIGURE 1.
6. Use opened and/or mixed sealer within two hours and discard any used sealer.
7. Air dry for 24 hours before putting the graphic into service.

Edge sealing improves the resistance to environmental damage and enhances the durability
of the graphics. We recommend using one of these easy options on graphic edges.
Seal Edges with Strips of
Overlaminate
This method can be used whether your graphic has overlaminate 8914 or a screen printed
clear coat applied.
Apply a 1/2 inch (13 mm) strip of overlaminate 8914 so each strip evenly straddles the
perforated film and substrate. Overlap the corners. See FIGURE 2 and FIGURE 3.
Important Note! Never allow film or overlaminate to touch the rubber window molding.
