Advanced Moisture Sealing Tape for Complex Surfaces
MARINE-SEAL 2 (Ref-DC260) is a double-coated, pressure-sensitive adhesive tape engineered for demanding marine environments. Its differential adhesion system features a strong-bonding polyether adhesive on one side and a silicone rubber layer on the other—both designed to leave no residue upon removal.
Thanks to its compressible construction and highly conformable silicone layer, MARINE-SEAL 2 excels in sealing complex or uneven surfaces where traditional gaskets may not be practical. The silicone rubber is 100% cured, highly hydrophobic, and has a low durometer, offering excellent reworkability and moisture resistance.
REACH and RoHS compliant, it's a clean, efficient solution for sealing tasks across a wide variety of marine applications.

Application Information
Proper Application For Best Results
-
1
Surface Preparation
Ensure surfaces are clean, dry, and free from oils or contaminants for optimal adhesion.
-
2
Measure & Cut
Cut MARINE-SEAL 2 to the required dimensions, allowing small overlap at joints where necessary.
-
3
Apply The Tape
Position with the polyether adhesive side against the primary substrate, applying firm pressure to activate adhesion.
-
4
Compress For Sealing
When securing the second surface, apply even pressure to compress the silicone layer for optimal sealing.
Frequently Asked Questions
-
How does MARINE-SEAL 2 compare to traditional gaskets?
MARINE-SEAL 2 offers several advantages over traditional gaskets, including easier application on irregular surfaces, better conformability to complex shapes, and clean removal without residue. It eliminates the need for custom gasket cutting and provides reliable sealing with its compressible silicone layer.
-
Can MARINE-SEAL 2 be repositioned during application?
Yes, MARINE-SEAL 2 allows for initial repositioning during application. The differential adhesion system provides enough initial tack to hold the tape in place while allowing adjustment before final pressure is applied to create a permanent bond.
-
How well does it work on textured surfaces?
MARINE-SEAL 2 is specifically designed for textured and irregular surfaces. Its silicone layer conforms to surface variations, filling gaps and creating an effective moisture barrier even on uneven substrates. The compressible construction helps maintain contact with both mating surfaces despite variations in gap width.
-
What temperature range can MARINE-SEAL 2 withstand?
MARINE-SEAL 2 maintains its performance properties across a wide range of temperatures typically encountered in marine environments. The silicone rubber component provides excellent temperature stability, while the adhesive system remains effective in both cold and warm conditions commonly found on vessels.
