If you're looking for a contaminant and water-tight seal between a graphic film and substrate, choose 3M™ 3950 Edge Sealer. For compatible films, it seals exposed film edges to prevent lifting due to cleaning or environmental exposure. This colorless, single-component liquid sealant can be used for materials that experience severe or prolonged exposure conditions or rigorous use, to minimize adverse effects. 3M sealers are among the best in the world, from a company with a long history of product excellence and innovation.

  • Clear liquid - acrylic/vinyl solution in xylene
  • Resists chemicals such as mild acids, mild alkalis and salts
  • Exceptional water resistance
  • 8-ounce dauber-top can

3M edge sealer 3950 (051128-82018) is required for certain 3M warranted graphics. See the base film's product bulletin for information. 3M 3950 can even be applied to film that has edge lifting or other signs of wear, to reduce further wear, though this usage doesn't conform with requirements for warranted graphics.

3M 3950 edge sealer is also known as 3950 Scotchcal.

Note: The edge sealer solvent may attack certain types of painted surfaces. You should always test first in an inconspicuous area before using.

Application Instructions

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:
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 the product, reducing future shelf life.

Applying the Liquid Edge Sealer:
1. Do not thin the sealer.
2 Use the dauber supplied with the edge sealer or a 1/4" (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.
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.

Shelf Life & Storage

Sealer 3950's Total Shelf Life, unopened, is 2 years. Cans are marked with both date of manufacture and use by date.

  • Tightly cap the container after each use. Opening the container introduces air that affects future shelf life.
  • Store in a cool, dry environment.
