Cyanoacrylate Silicone Adhesives Guidelines for Use
Cure speed is very fast, so ensure that the parts are properly aligned before assembling with adhesive. KANGLIBANG K770 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 is dependent on the substrates to be bonded. Best results come with close-fitting parts. Larger bondline gaps will give longer cure times. KANGLIBANG K770 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.
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.
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.
