    Tommy Tape® Self-Fusing Silicone Tape The next generation of tape is here — premium, adhesive-free repair and sealing tape for fast fixes at home, on the job, and on the road. Tommy Tape self-fusing silicone tape saves time and money across plumbing, electrical, automotive, marine, garden, and industrial jobs. Unlike vinyl or cloth tapes, it uses no adhesive. Instead, it chemically bonds (self-fuses) to itself on contact to form a tough, flexible, and permanently water-tight wrap — even underwater. Why you’ll love it Extreme temperature range: operates from −65 °F to +500 °F (approx. −54 °C to +260 °C). Electrical safety: insulates up to 8,000 V per layer (typical PVC electrical tape ≈ 600 V). Leaves no residue: no adhesive means no sticky mess when removed. Weather- & waterproof: seals within seconds; ideal for outdoor and marine use. Flexible & form-fitting: stretches over 300% to wrap irregular shapes, fittings, and bends. Built to last: resists UV, oil, salt, and common chemicals; helps combat corrosion. Popular uses Plumbing: emergency seals on copper, PVC, and garden hoses; patch vacuum and pool hoses. Electrical: bundling and insulating leads, wire harnesses, extension-cord strain relief (power off first). Automotive & 4×4: wrap frayed looms, protect hoses, create quick roadside fixes. Marine: mast boot wraps, deck-side waterproofing, salt-spray protection. Tools & grips: re-grip shovels, rakes, wheelbarrows, gym dumbbells, walking canes. Sports & DIY: re-grip golf clubs, tennis/pickleball paddles; improve wheelchair and shower-chair grip. Home & garden: weatherproof outdoor cables, protect back-yard gear and appliances. Industrial: protective wraps on fittings, temporary containment where adhesives aren’t suitable. How to apply (best results) Prep: Turn power/water off where applicable. Clean and dry the area if possible. Start & anchor: Peel off the liner, stretch the tape as you begin to wrap, and press the starting end onto itself to anchor. Stretch & overlap: Stretch to at least 2× its length (more stretch = stronger fuse). Overlap each wrap by ½ width. Build layers: Add additional layers for higher pressure, stronger seals, or increased dielectric protection. Finish: End the wrap on itself and press firmly. Full fusion develops quickly; handle with care while it sets. Remove: Cut off (do not unwind) when it’s time to replace — it leaves no residue. Specifications Material Silicone rubber (self-fusing) Adhesive None (bonds to itself on contact) Dielectric Strength Up to 8,000 V per layer (build layers for higher insulation) Temperature Range −65 °F to +500 °F (approx. −54 °C to +260 °C) Resistance UV, oil, salt, weather, and common household/automotive chemicals Water Performance Weatherproof & waterproof; can be applied underwater in many scenarios Elongation Stretches over 300% for tight, conformal wraps Removal Cut off to remove; no sticky residue Colours / Sizes Varies by SKU (see options above) Better than traditional tapes Feature Tommy Tape Self-Fusing Silicone Vinyl / Cloth Electrical Tape Adhesive No adhesive (self-fuses) Pressure-sensitive adhesive (leaves residue) Waterproof Seal Yes — seals in seconds; can be used underwater Limited; adhesive can lift when wet Dielectric Strength Up to 8,000 V per layer Typically ~600 V Temperature Range −54 °C to +260 °C Narrower range; softens or becomes brittle UV/Chemical Resistance Excellent (UV, oil, salt, chemicals) Moderate; can degrade outdoors Residue on Removal None — clean cut-off Commonly leaves sticky residue FAQs Can I use it on live electrical circuits? No. Always switch power off before wrapping. Build sufficient layers for the required insulation, and follow local electrical standards. Will it stick to wet or oily surfaces? Because it bonds to itself (not the substrate), it can often be applied in damp or even underwater situations. For best results, clean and dry the area first. Is it reusable? Once fused, it forms a single mass. Cut it off to remove; it won’t unwind. Apply a fresh wrap if needed. What isn’t it for? Not a substitute for permanent structural repairs. Avoid use on fuel lines or high-pressure systems without proper engineering sign-off. Notes: Performance values are typical and depend on application method, substrate, and number of layers. Always test on a small area first. Follow safety guidelines for electrical and pressurised systems.

Technical Data Chemical Base 1-C silicone Density (uncured) 1.0 kg/l approx. Skin Time 10 min approx. Tack-free time 20 min approx. Curing Time 24 hours approx. Cure Mechanism Moisture-curing Cure Type Acetoxy Application temperature 5 - 45°C Mechanical/Physical Properties Tensile Strength 1.0 N/mm2 approx. Shore a Hardness 25 approx. Ultimate Elongation 600% approx. Application Details Ensure all surfaces are clean, dry and free from dust, grease and loose material. Remove all old gasket material from mating surfaces before cleaning with a residue-free solvent and allowing drying properly. Cut the nozzle at a 45° angle to the desired bead size (3 mm is suitable for most applications) then apply a continuous and even bead along the joint. Cure Mechanism SikaSeal® Appliance cures by reaction with atmospheric moisture. The reaction thus starts at the surface and proceeds to the core of the joint. The curing speed depends on the relative humidity, temperature and thickness of the sealant. At low temperatures, the water content of the air is lower and the curing reaction proceeds more slowly. Clean Up Uncured, excess SikaSeal® Appliance may be removed with Sika® Remover-208 or another suitable solvent. Once cured, the excess sealant can be trimmed away from the edges with a knife. Application Conditions/ Limitations Restrictions On Use SikaSeal® Appliance is not recommended for use in applications where it will be permanently exposed to temperatures exceeding 250°C or in contact with fuels. The above information is offered for general guidance only.
