Bostik Ultra-Strong Clear Super Glue (Liquid, Odourless, Fast-Setting) Ultra-Strong Clear Super Glue is a professional-grade, medium-viscosity liquid adhesive designed for quick, reliable repairs on most non-porous materials. It forms an instant high-strength bond that sets in seconds and reaches full cure in 24 hours. The clear, solvent-free formulation is virtually odourless for a cleaner, more comfortable user experience, and its slightly flexible bond helps resist knocks and everyday drops once cured. Why You’ll Love It Fast setting: bonds in seconds to get you back to work quickly. Ultra strong: high strength once fully cured for durable, long-lasting repairs. Water & heat resistant: engineered to stand up to common household moisture and temperature swings. Odourless & solvent-free: cleaner application with a safer, low-irritation formula. Slightly flexible bond: helps absorb minor shocks and everyday handling. Ideal Materials Best results on clean, dry, non-porous surfaces including: China, ceramics and porcelain (non-permanent on items subject to frequent washing) Rubber and elastomers Metals and metal components Jewellery repair (non-food contact) Many rigid plastics* *Not suitable for polyethylene (PE), polypropylene (PP) or PTFE (Teflon?). Not recommended for permanently bonding glass, high-alkaline materials, or items that are regularly washed. Avoid paper and other highly porous substrates. Where It Excels Quick household fixes (knobs, clips, figurines, trim) Hobby & craft assembly (non-porous parts) Workshop touch-ups and small component repair Office and general repair kits How It Works This liquid cyanoacrylate reacts with trace moisture on surfaces to polymerise rapidly, forming a high-strength thermoplastic bond. The medium viscosity helps wet out tight-fitting parts while minimising run-off when applied sparingly. Before You Start Surface prep: Ensure both surfaces are clean, dry, and free from dust, oil, rust, release agents or old adhesive. Lightly abrade glossy plastics/metal where appropriate and wipe clean. Dry fit first: Check alignment, clamping and support so parts come together quickly and accurately. Protect work area: Use disposable backing and keep caps, tissues and a small amount of acetone or nail-polish remover handy for cleanup. Application (Liquid) Open: For first use, attach/screw the nozzle and remove the cap. Apply a tiny amount: Place a small drop on one surface only. More glue can slow cure and weaken the joint. Assemble: Bring parts together immediately and hold with firm, even pressure for ~20 seconds. Avoid movement during initial set. Let it cure: Handling strength develops quickly; allow 24 hours for full cure and maximum performance. Clean-Up & Rework Fresh squeeze-out: Wipe carefully. Small residues may be treated with acetone/nail-polish remover and gently scraped once softened. On skin: Do not pull apart. Soak in warm, soapy water and gently roll/peel. Use a blunt tool (e.g., spoon handle) to separate bonded skin slowly. Pro Tips for Best Results Use the smallest effective drop-thin bondlines are stronger. Maintain close-fitting joints; gaps reduce cure speed and strength. Avoid bonding on PE, PP, PTFE and materials with heavy plasticisers or strong alkalinity. Allow the full 24-hour cure before exposing to stress, moisture or heat. Storage & Shelf Life Store tightly closed in a cool, dry place below 25?°C, away from direct sunlight. Typical shelf life: 12 months from manufacture when stored as directed. Safety Cyanoacrylate adhesive: bonds skin and eyes in seconds. Keep out of reach of children. Wear protective gloves and eye protection. In eyes: rinse immediately with water and seek medical attention.

Yes, many rubbers bond well; ensure surfaces are clean and oil-free. Is it dishwasher-safe? Not recommended for items that are regularly washed, soaked or immersed. Why shouldn’t I flood the joint? Excess adhesive slows cure and weakens the bond-thin layers perform best. Disposal Allow small residues to cure fully (exposed to air) before disposal in accordance with local regulations.
