Jargon Buster

Cyanoacrylate

The chemical name for super glue. This fast-curing adhesive polymerises rapidly when exposed to moisture present in the air or on surfaces, creating strong bonds within seconds. All super glues are cyanoacrylate-based adhesives.

Viscosity

Refers to the thickness or flow characteristics of the adhesive. Low viscosity super glues are thin and runny, ideal for penetrating tight gaps and capillary action bonding. Medium viscosity offers versatility for general applications. High viscosity and gel formulations are thicker, providing gap-filling properties and non-drip performance on vertical surfaces.

Thixotropic Gel

A specialist non-drip gel formulation that maintains its position on vertical and overhead surfaces without running. Perfect for gap-filling applications and precise bonding work where adhesive migration would compromise the repair.

Activator/Accelerator

An aerosol spray product that dramatically speeds up the curing process of cyanoacrylate adhesives. Particularly useful when bonding non-porous materials, working in low-humidity conditions, or when instant handling strength is required.

Rubber-Toughened

A modified super glue formulation with added elastomers providing increased flexibility, impact resistance, and peel strength. Ideal for applications subject to vibration, mechanical stress, or thermal expansion and contraction cycles.

Cure Time

The duration required for the adhesive to reach full bond strength. Initial bonding with super glue occurs within 10-30 seconds, but complete cure typically takes 24 hours for maximum strength development and optimal performance characteristics.

How to Choose the Right Super Glue

Material Compatibility: Whilst most super glues bond a wide range of materials, some formulations are optimised for specific surfaces. Standard cyanoacrylate works excellently on plastics (excluding polyethylene and polypropylene), metals, ceramics, and rigid materials. For porous materials like wood, leather, or card, consider slower-setting formulations that allow penetration. UPVC applications benefit from specialist products paired with activator sprays for optimal bond strength.

Viscosity Requirements: Low viscosity adhesives flow readily into tight joints, hairline cracks, and capillary spaces, making them ideal for precision work and invisible bonds. Medium viscosity offers the most versatility for general repairs and typical applications. High viscosity and gel formulations provide gap-filling capabilities up to several millimetres and won't drip on vertical or overhead applications, remaining exactly where applied.

Application Environment: Consider your working conditions and performance requirements. Rubber-toughened super glues offer flexibility and superior resistance to impacts, vibration, shock loading, and temperature cycling. Thixotropic gels maintain position on vertical surfaces without sagging. Black formulations provide more discreet finishes on dark materials, whilst standard clear adhesives remain virtually invisible when cured.

Applicator Style: Brush-on applicators available from Tooled-Up offer precise control for detailed work and reaching awkward areas. Nozzle bottles suit general applications and allow controlled dispensing into recesses. Easy-flow bottles provide consistent, controlled dispensing without requiring excessive pressure. Consider purchasing multiple formats for different job requirements to maximise efficiency.

Quantity and Value: Professional users should consider larger volume packs or multi-packs for better value. Remember that cyanoacrylate adhesives have a limited shelf life once opened (typically several months with proper storage), so balance quantity against your typical usage rates to avoid waste through premature curing.

Safety Information

Super glue requires careful handling to ensure safe use in accordance with HSE and COSHH regulations. Always work in a well-ventilated area, as cyanoacrylate adhesives release vapours that may cause respiratory irritation, particularly in confined spaces. Wear appropriate eye protection to prevent accidental contact with eyes, which can cause serious injury requiring immediate medical attention. Never attempt to remove adhesive from eyelids—seek emergency medical assistance immediately.

Skin bonding is the most common accident with super glue. If skin becomes bonded, do not attempt to forcibly pull surfaces apart, as this may cause tearing. Instead, immerse the affected area in warm soapy water and gently peel surfaces apart using a blunt object. Keep a dedicated debonding agent in your toolkit for emergencies. Never use super glue near the eyes, mouth, or on large areas of skin. The adhesive bonds skin instantly and can cause burns through the exothermic curing reaction.

Store super glue in a cool, dry location away from heat sources, direct sunlight, and moisture. Keep containers tightly sealed when not in use, as exposure to atmospheric moisture will cause the adhesive to cure within the bottle. Always read and follow the manufacturer's safety data sheets (SDS) and comply with COSHH regulations when using these products in workplace environments. Dispose of empty containers according to local regulations. Keep out of reach of children at all times.

Frequently Asked Questions

How long does super glue take to set and fully cure?
Initial bonding occurs within 10-30 seconds on most surfaces, providing handling strength almost immediately. However, full cure strength develops over approximately 24 hours. For maximum bond strength and durability, avoid subjecting repairs to significant stress during this curing period. Using an activator spray can reduce cure times to just seconds when working with non-porous materials or in low-humidity conditions.

Can super glue withstand outdoor conditions and weathering?
Once fully cured, most quality super glues offer good water resistance and can withstand typical UK weather conditions. However, prolonged exposure to moisture, UV light, and temperature extremes may gradually degrade the bond over time. For critical outdoor applications or joints requiring long-term weatherproofing, consider specialised weatherproof adhesives, polyurethane adhesives, or two-part epoxy systems specifically designed for exterior use.

What's the difference between liquid super glue and gel formulations?
Standard liquid super glue has low viscosity and flows easily through capillary action, making it ideal for tight joints, small gaps, and applications requiring adhesive penetration. Gel formulations like Bondloc B454 are thicker and thixotropic, meaning they stay exactly where you apply them without running or dripping. Gels are perfect for vertical surfaces, overhead work, gap-filling applications up to 2-3mm, and situations where adhesive migration would compromise the repair. Both offer similar ultimate bond strength when fully cured.

Why won't super glue bond certain plastics or materials?
Some plastics, including polyethylene (PE), polypropylene (PP), PTFE (Teflon), and silicone, have extremely low surface energy that prevents effective bonding with standard cyanoacrylate adhesives. These materials require surface preparation with plasma treatment, primers, or specialist adhesives formulated for low-energy plastics. Very smooth, oily, or contaminated surfaces also resist bonding—clean thoroughly with a suitable degreaser or solvent before application. Using an activator spray can significantly improve adhesion on difficult surfaces.

How can I prevent super glue from curing in the bottle?
Store super glue upright in a cool, dry place with the cap tightly sealed immediately after use. Moisture in the air causes cyanoacrylate to cure, so minimising exposure is crucial. Wipe the nozzle clean before replacing the cap to prevent blockages. Some professionals store opened bottles in airtight containers with silica gel packets to absorb moisture. Refrigeration can extend shelf life, but always allow the bottle to return to room temperature before use to prevent condensation inside the container, which will cause premature curing.
