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.

FAQs
Can I use it on flexible rubbers? 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.
