tesa 54411 Sealing Adhesive Tape, 50 mm x 12 m, 1.1 mm thick

tesa® 54411 is a sealing tape designed to replace traditional liquid sealants, eliminating curing times and ensuring an immediate, long-lasting seal against water, dust, and moisture. 

Its UV-resistant ionomer film backing and soft acrylic adhesive mass make it ideal for use in demanding environments and on irregular surfaces. 

Benefits

• Zero waiting time: The acrylic adhesive wets out the surface instantly, reducing downtime compared to traditional chemical sealants. 
• Conformability: Easily adapts to complex profiles, joints, and rivet heads with minimal applied pressure. 
• Paintable and writable finish: After removing the top siliconized PET liner, the outer surface can be painted or marked without compromising the seal. 
• High outdoor durability: Certified UV resistance for up to 104 weeks, along with excellent water, aging, and abrasion resistance. 
• Safe formulation: Completely free from solvents and fluorinated chemicals (PFAS). 

Main Sectors and Applications

Thanks to its high conformability and instant seal, tesa® 54411 tape ensures fast and reliable sealing across various industries: 

• Automotive, campers, and transport: Instant and permanent sealing of joints, profiles, welds, and rivets. 
• Construction and roofing: Roof insulation and protection of cracks or fittings against water, moisture, and dust infiltration. 
• Industrial and agricultural maintenance: Fast and durable repair of plastic tanks, cisterns, silos, and containers. 
• Plumbing and water systems: Emergency repair of water leaks and applications in wet environments such as swimming pools and containment basins. 

How to Apply tesa® 54411 Sealing Tape

Applying tesa® 54411 is fast, clean, and requires no waiting time for drying or curing: 

1. Surface preparation: Ensure the substrate is clean and dry. To maximize initial adhesion or speed up dwell time on critical surfaces, use specific primers. 
2. Cutting and positioning: Cut the tape to the desired length (not hand-tearable) and position it over the area to be sealed. 
3. Initial pressure: Apply light pressure to the tape. The protective liner placed on the top side facilitates smooth application and initial pressure onto the soft adhesive. 
4. Liner removal: Once initial pressure has been applied, remove the top transparent PET protective film to expose the highly abrasion-resistant backing. If needed, the outer surface is immediately ready to be painted or written on.
