3M™ Extreme Sealing Tape 4411N(case)

3M™ Extreme Sealing Tape 4411N is a single-coated, pressure-sensitive sealing tape developed for challenging sealing applications. It combines a tough, flexible, abrasion-resistant ionomer backing with a thick, highly conformable multi-purpose acrylic adhesive. The tape is designed to seal over joints, seams, penetrations and other areas where a durable seal is required. Its translucent construction allows the tape to conform over irregular surfaces while providing resistance to moisture, high-pressure water, thermal shock and outdoor exposure. The technical data also reports UV resistance based on accelerated aging tests.

Key Features

• Highly conformable: Thick acrylic adhesive adapts well to challenging sealing surfaces.
• Tough ionomer backing: Flexible and abrasion resistant for demanding applications.
• Immediate sealing: Provides a seal immediately after application, while full bond strength generally develops after 24 hours.
• Moisture protection: Excellent moisture and high-pressure water resistance.
• Temperature resistance: Short-term temperature tolerance up to 149°C and long-term tolerance up to 93°C.
• Overlap capability: The adhesive bonds to the ionomer backing, allowing overlapping tape sections to form sealed joints.
• Outdoor durability: Samples passed adhesion testing after 2,000 hours of accelerated UV aging.

Applications

• Joint and seam sealing
• Sealing around penetrations
