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.

Sikasil®-670 Fire adheres without primers and/or activators APPLICATION METHOD / TOOLS Sikasil®-670 Fire is supplied ready to use. After the necessary substrate preparation, insert a suitable backing rod to the required depth and apply any primer if necessary. Insert a foil pack or cartridge into the sealant gun and extrude Sikasil®-670 Fire into the joint making sure that it comes into full contact with the sides of the joint and avoids any air entrapment. Sikasil®-670 Fire sealant must be firmly tooled against the joint sides to ensure adequate adhesion. It is recommended to use masking tape where exact joint lines or neat lines are required. Remove the tape within the skin time. Do not use tooling products containing solvents. CLEANING OF TOOLS Clean all tools and application equipment immediately after use with Sika® Remover-208 and/or Sika® TopClean T. Once cured, residual material can only be removed mechanically. FURTHER DOCUMENTS ▪ Safety Data Sheet (SDS) ▪ EN 13501-2 classification report ▪ ETAG 026 assessment report ▪ Brochure Sika Fire Protection Solutions LIMITATIONS ▪ Sikasil®-670 Fire cannot be overpainted. Colour variations may occur due to exposure to chemicals, high temperatures and/or UV-radiation (especially with the colour shade white). However, a change in colour is purely of aesthetic nature and does not adversely influence the technical performance or durability of the product. ▪ Do not use Sikasil®-670 Fire on natural stone. Do not use Sikasil®-670 Fire on bituminous substrates, natural rubber, EPDM rubber or on any building materials which might bleed oils, plasticizers or solvents that could attack the sealant. ▪ Do not use Sikasil®-670 Fire to seal joints in and around swimming pools. ▪ Do not use Sikasil®-670 Fire for joints under water pressure or for permanent water immersion. ▪ Do not expose uncured Sikasil®-670 Fire to alcohol-containing products as this may interfere with the curing reaction.

Can I use Command™ Products on glass windows? It is okay to use Command™ Products if the glass is not exposed to direct sunlight and not flooded with water. For glass shower doors use our special Water-Resistant line of products (blue strip) which are clearly marked on our packaging.   Will Command™ Products stick to brick? No. Command™ Products are intended for mostly smooth surfaces such as those listed above. However, our products will stick to painted, smooth cinder block (the type found inside many school and office buildings).   Can I use Command™ Products on fresh paint? Paint should be fully cured (check paint can for manufacturer's cure time) before using Command Products. We recommend waiting 28 days before use on fresh paint. Also, alcohol may remove or dull the surface of fresh paint.   Can I use Command™ Products on wallpaper? No. Most wallpapers are too delicate and can tear when adhesives are applied.   Will it hold soundproofing acoustic foam board or decorative plates? Yes, provided the item is within the weight limit specified for Command™ Picture Hanging Strips. We do not recommend hanging tapestry or other fabrics. For decorative plates, please ensure there is a smooth surface for the strip to adhere to. Do not hang valuable or irreplaceable items.
