can vinyl go underwater?
I have been asked to add lettering to a load of scuba diving equipment.
I’ve got just basic ritrama 5 year vinyl in stock, I’m assuming this won’t be good enough?
In which case is there a specific vinyl i would need for use underwater?

Dave if you do a search, this topic has been covered before, I think it was about swimming pools, we have put vinyl on boats with no problems.

but will depend on the substratePeter

Hi Dave
We have tested Metamarks MD-P and MD3 on dive Cylinders both did fine we have never had any complaints and continue to use MD-P, both solvent based adhesive, but as Peter said its very much down to the substrate and application.
Ive also tested MD-P in dish Washer test, over 100 cycles at 85Deg and still OK, just a half mil or so loss of adhesive around edgehope this helps

i would agree with what has been said too… A good cast vinyl should do the job. once on, give it a heat to help speed up a good adhesion.

how about applying the vinyl while underwater? anyone tried?

I’d be using a cast with hitac adhesive myself. That said, 3M 7725 is a marine grade vinyl, so should do the trick, depending on the quality of the surface it is going on I guess.

I don’t see it as being too much of a test for a decent quality vinyl to be honest (dishwasher is a lot fiercer, due to the addition of that much heat) Reasonable vinyl can withstand petrol, diesel, truck wash, direct sunlight, ice and snow, car washes, scratches down the side, especially on luton vans, I’ve done loads of boats etc. Putting it in the sea for a few hours at a time really can’t matter. Swimming pool chlorine may be an issue, but I can’t see it as the kayaks are used in the pools for lessons, they don’t have any problems. As with all applications substrate is an important issue, if the vinly sticks to the coating, but the coating is rough/poor or doesn’t stick to the object, it’s a problem waiting to happen. Vinyl doesn’t seem to like de-icer though, any ideas why??
