PRODUCT DATA SHEET
Product Reference Cyanoacrylate Adhesive PST20
PST20 is an ethyl Cyanoacrylate adhesive of very low viscosity. It is especially suitable for very fast bonding of close fitting surfaces on rubbers, plastics and filled rubbers. It’s very low viscosity and wetting ability allows wicking in and post application.
Rubber O ring manufacture. Single component adhesive.
Bonds in seconds, rubbers, plastics and ceramics. 100% Solventless.
Bonding of foams and filled rubbers. Economical in use.
Bonding of electronic components. Very rapid bonding at room temperature.
Locking small screws and fasteners. Excellent wicking in properties.
Fine instrument manufacture.

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.
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% +.
Prior to use consult relevant Material Safety Data Sheet.
When continuously used local fume extraction is recommended.
Contains Cyanoacylate ester. Use in a well ventilated environment.
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.
Keep out of reach of children.
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.
Available in 20g, 50g, and 500g packs.
