GB80 is a black ethyl cyanoacrylate, with higher peel and shock resistance than other grades. GB80 has a longer setting time than regular Cyanoacrylate adhesive which allows enough time for users to put materials together 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. GB80 is a one-component, solvent-free system and does not require the use of a catalyst, heat or clamps. When a thin layer of GB80 applied between two surfaces comes into contact with atmospheric moisture, a rapid polymerization occurs producing the ultimate bond.
1. Make sure the surfaces to be bonded are clean and dry (preferable to solvent-wipe plastics glass, and rubber, and to acid-treat metals). 2. Dispense a drop or drops to one surface only. Apply only enough to leave a thin film after compression. 3. Press parts together and hold firmly for a few seconds. Good contact is essential. An adequate bond develops in less than one minute. (Maximum strength is achieved in 24 hours). 4. Wipe off excess adhesive from the top of the container and recap, GB80 if left uncapped, may deteriorate by contamination from moisture in the air. 5. Because GB80 polymerises on contact with moisture surfaces, sometimes whitening will occur on the surface of the container or the bonded materials. Should this happen, wipe surfaces well with BD series De-bonder.
TECHNICAL DATA SHEET FOR GB80
Use with proper ventilation. Avoid contact with skin and eyes.
2. If contact with skin occurs, rinse with warm water or dissolve gradually with appropriate de-bonder. Do not try to remove forcibly. 3. If adhesive gets into eye, keep eye open and rinse thoroughly. Seek medical attention immediately. 4. Ke ep well out of reach of children. 5. Keep adhesive in a cool, dry place 20-25oC. For long term storage, refrigeration (5oC) is recommended.
For safe handling of this product consult the Material Safety Data Sheet.
REMOVAL OF CURED CYANOACRYLATE
STORAGE Store in a cool area and out of direct sunlight. Refrigeration to 5° C gives optimum storage stability.
Cured cyanoacrylate may be removed frommost substrates, and parts disassembled, withade-bonder. It is not possible to fully remove cyanoacrylate from fabrics
Cyanoacrylates are supplied in 50g, 500g and bulk packs
DIRECTIONS FOR USE Bond speed is very fast so ensure that parts are properly aligned before bonding.
Activators may be required if there are gaps or porous surfaces. Some plastics may require application of a primer.
Ensure parts are clean, dry and free fromoil and grease.
Product is normally hand applied from the bottle. Apply sparingly to one surface and press parts firmly together until handling strength is achieved. As a general rule, as little cyanoacrylate as possible should be used – over application will result in slow cure speed and lower bond strength.
Please contact your representative for further advice on dispensing solutions.
CHEMICAL / SOLVENT RESISTANCE
Cyanoacrylates exhibit excellent chemical resistance to most oils and solvents includingmotor oil, leaded petrol, ethanol, propanol and freon. Cyanoacrylates are not resistant to high levels of moisture or humidity over time.
