Application description:
Instant adhesives, or cyanoacrylates, cure very quickly
when conf ned between surfaces. Surface humidity on
the substrates triggers the cure reaction, which moves
from the substrate surfaces towards the middle of the
adhesive joint. Cyanoacrylates are typically chosen for
bonding small to medium-size parts to achieve extremely
fast curing. Due to their limited gap-f lling capacity they
require close-f tting surfaces. Their adhesion to most
substrates is excellent and the bonding strength in
shear and tensile mode is very good.
They should not be used on f oat glass or glazed
ceramics, but can be used on GRP. Bonds continuously
exposed to water need proper adhesive selection and
ageing evaluation.
Surface preparation:
Correct surface preparation is a key factor in assuring
the total success of any adhesive performance. A)
Degrease, clean and dry all surfaces before applying
the adhesive. For this you can use the general-purpose
cleaner LOCTITE® SF7063 B) To improve adhesion on
diffi cult-to-bond materials such as PP PE PTFE etc.,
apply activator LOCTITE® SF770
