DIRECTIONS FOR USE

Ensure surfaces are clean and dry, apply adhesive to one surface. Press surfaces together and hold for 10 seconds or as indicated below. Cure speed is rapid so exercise care when aligning. Cure performance can be enhanced if necessary, by using selected activators.

TYPICAL BONDING TIMES

Plastics 5 - 60 seconds depending on substrates.
Rubbers 2 - 20 seconds depending on substrates.
Metals (degreased) 10 - 60 seconds depending on substrates.

LIMITATIONS

Ensure surfaces are degreased prior to bonding. Ensure surfaces are close fitting.
This product is not suitable for permanent glass bonding, or applications where the bonded joint may be immersed in water.

RELATIVE HUMIDITY CONDITIONS

Where possible the working environment should have a relative humidity of 50% +.

CAUTION

Prior to use consult relevant Material Safety Data Sheet.
When continuously used local fume extraction is recommended.
Contains Cyanoacrylate Ester. Use in a well ventilated environment.
Bonds skin and eyes in seconds, wear safety goggles if danger of splashing.
In the event of inadvertent skin bonding separate bonded skin tissue carefully by peeling apart gently with a blunt instrument. Preferably after soaking in warm soapy water.
Use hand cream or disposable gloves.
Keep out of reach of children.

STORAGE

Store in original sealed upright container between +3°C and 20°C in a dry area out of direct sunlight. The lower the temperature the longer the ultimate shelf life, but bring to room temperature before use.
