Title: Cyano and water
Post by: Terry on January 25, 2015, 10:05:27 am
Is Cyano adhesive OK for areas that occasionally  get wet, ie above the waterline.


Cheers, Terry.

A good quality one in the medium range should be alright for a few years.  Mind you, it is designed to degrade on human skin.   %)

Can you use epoxy resin. ?  This will last.

I did a test a couple of years ago, as this question kept coming up, I made a small styrene box about 2" square and 2" deep,  using Admiralty Glues Professional thin cyano and filled it with water and put it on a shelf in the workshop I remembered it 6 weeks later it was still in one piece with water in it, how much more water proof can you get %% %%

natural evaporation would empty the vessel, so how did you overcome this? a weighted vessel in water (as this is what the usual test would be for - keeping water out) means it does not matter what the water level is and can be maintained as the water evaporates, any water entering is easy identified.

I said it had water in it, obviously some had evaporated, the point is it didn't leak out and the joints were intact, in fact it took some force to break the box apart, so I don't see any difference whether you are keeping water out of a box or in a box the glue in the joints is still being tested %%
