About adhere Professional Cyanoacrylate Adhesives

adhere Cyanoacrylate Adhesives are superior quality, high purity single part adhesives which have numerous applications in all aspects of high technology, high performance assembly. Curing at room temperature in seconds, they provide excellent bond strength on a wide range of similar and dissimilar substrates including rubber, plastics, metal, wood, leather, ceramics, ferrites, stone, cork, composites and paper. The range includes surface-insensitive, fast cure and low odour, low blooming formulations.

Single component systems, adhere Cyanoacrylate Adhesives are fast and easy to use. They require no mixing or heating, and parts being bonded do not need clamping. They are solvent free. They achieve high tensile and shear strengths.

Cyanoacrylate adhesives (CA’s) are sometimes generically known as “superglues” or “instant adhesives”.

Their high quality formulation and manufacture ensures excellent manufacturing repeatability and high stability – facilitating long shelf life. The application of adhere Cyanoacrylate Adhesives can be automated easily for highly efficient production line use; ask us about a complete line of suitable dispensing equipment.

The range also includes an activator for even faster cures, and a primer which facilitates bonding of difficult to bond plastics.

Applications

General purpose
ADH 9420	Very low viscosity, general purpose cyanoacrylate adhesive. Wicking grade.	High strength bonding of most plastics, rubber, metals and other common substrates.

ADH 9416	High viscosity, surface insensitive cyanoacrylate adhesive. Gap filling.	Formulated for bonding plastics, rubbers, wood, paper, cardboard, leather, metals and other common substrates. Suitable for porous substrates where gap fill is required (e.g. foam rubber, cork).
ADH 9485	High viscosity, impact and peel resistant formulation.	Develops strong bonds on most metals, plastics or rubbers. Specifically formulated for applications requiring both a high viscosity and resistance to peel forces and impact.
ADH 9454	Surface insensitive cyanoacrylate adhesive with a very high, gel viscosity. Non-drip.	Formulated for high strength general purpose bonding of most metal, wood, card, plastic, rubber, leather, fabrics and other common substrates. It is also suitable for use on vertical and overhead surfaces as will not drip or slump.
Low odour, low bloom
ADH 9408	Low viscosity, low odour, low bloom cyanoacrylate adhesive.	Suitable for most plastics, rubbers and other common substrates. Low odour, reduced need for ventilation. Low bloom, no whitening. Recommended for use on close-fitting parts and smooth even surfaces. Wicking grade.

Rubber toughened
ADH 9105	High viscosity, black, rubber toughened cyanoacrylate adhesive.	With higher impact, humidity and temperature resistance, provides a more flexible bond than standard cyanoacrylate adhesive. Can be used in temperatures up to 105°C (125°C intermittent). Suitable for metals, plastics and rubbers. Gap filling and resists vibration, thermal shock. Also used on pcb’s to provided strain relief, wire tacking. Loudspeakers.
ADH 9480	Medium viscosity, black, rubber toughened cyanoacrylate adhesive. High temperature resistance.	Higher peel and shock resistance. Has a longer setting time than other grades which allows more time for users to assemble substrates after application. It has been specially formulated to achieve the strongest possible bond between well-mated, non-porous surfaces, such as rubber, metals, plastics, etc.
Activator/accelerator
ADH 9455	Cyanoacrylate activator.	Accelerates cure of cyanoacrylate adhesives. Cures excess adhesive, minimises blooming. Assists cure in non-interfacial applications, and for slower, high viscosity cyanoacrylate adhesives. Treatment of porous substrates to prevent too much adhesive absorption.
Primer
ADH 9770	Cyanoacrylate primer.	Improves the adhesion of cyanoacrylate adhesives to difficult to bond plastics such as polypropylene, polyethylene, silicone rubber and even ptfe (Teflon®). Dries in less than 30 seconds, useful life on part is up to 8 hours.

Guidelines for Use

Cure speed is very fast, so ensure that it properly aligned the parts before assembling with adhesive. ADH 9455 Activator may be used if there are any gaps or porous surfaces. Some plastics or rubbers may have better bonding performance with the use of ADH 9770 Primer. Ensure parts are clean, dry and free from oil and grease. If necessary, use a suitable cleaner prior to bonding. Cyanoacrylate adhesives can be hand applied direct from the bottle – a suitable dispensing needle can be added to the bottle nozzle for more precision. The application of adhere Cyanoacrylate Adhesives can be automated easily for highly efficient production line use; ask us about our complete line of suitable dispensing equipment.

Apply the adhesive sparingly to one surface and press parts firmly together until handling strength is achieved. As a general rule, as little cyanoacrylate adhesive as possible should be used – over-application will result in slow cure speed and lower bond strength.

We do not normally recommend cyanoacrylate adhesives for structural glass bonding. Whilst the initial bond strength may be high, it tends to decrease with age. We have other structural adhesives, including light curing adhesives, which are likely to give more durable and robust bonds.

Cure speed
Cure speed is dependent on the substrates to be bonded. Best results come with close-fitting parts. Larger bondline gaps will give longer cure times. ADH 9455 Activator can be used to increase cure speed (some loss of optimal bond strength can result). Low temperature and low humidity will tend to slow up the curing process.

Chemical resistance
adhere Cyanoacrylate Adhesives have very good chemical resistance to most oils, leaded petrol, alcohols and light duty cleaning solvents. Cyanoacrylates are not resistant to high levels of moisture and humidity over time.

Storage
Store in a cool, dry area out of direct sunlight to achieve 12 months shelf-life. Refrigeration to 5 °C will help give optimal stability.

ADH9455	Protect from freezing and direct sunlight. Store in a dry place. Do not store near heat sources or expose to high temperatures. Keep away from heat, sparks and open flame. Avoid heat, flames and other sources of ignition. Avoid exposing aerosol containers to high temperatures or direct sunlight.
ADH9770	Store in cool, well ventilated area. Keep container tightly closed. Keep away from sources of ignition. Keep away from direct sunlight. Prevent the build-up of electrostatic charge in the immediate area. Ensure lighting and electrical equipment are not a source of ignition. Avoid storing with strong oxidising agents and strong acids and avoid storing in direct sunlight, on hot surfaces, when sources of ignition, flames or heat could be present.

ADH 9455 Activator
Apply activator to parts to be bonded, allow the solvent to evaporate, and then immediately apply adhesive and assemble. Alternatively, ADH 9455 Activator can be sprayed onto exposed cyanoacrylate adhesive bondlines for immediate cure.

ADH 9770 Primer
Apply primer only to substrates requiring priming (low surface energy plastics, rubbers, etc), allow the solvent to evaporate, and then immediately apply adhesive and assemble. Primer will also increase cure speed.
