Sealant w/o adhesive

[heritage]

Rich, do you think that elastomeric would work on the sharp edges of the ends of hose clamps?

Absolutely. But I have some little red plastic push on covers for the hose clamp tails. The stupid things are about 25 cents apiece but they are removable and reusable. Since clamps are occasionally removed I think the red plastic covers are the way to go for clamp tails.

capta: I recommend Sudbury 321 Elastomeric Marine Sealant. It is available in a variety of colors and will stick to mast aluminum and stainless steel cotter pins. My rigger put me on to it. He and now I use it to coat cotter pins to protect against snagging. The great thing about it is when you need to remove it all you do is grab a piece of it and pull. It comes off cleanly without leaving lots of little pieces to pick off. Skins over quickly and cures in one day at 70 degrees.

I got onto as a result of a bunch of PS testing. It struck me as the most predictable of the low-strength sealants. Also better adhesion to polyethylene, though flaming the surface really helps.

Where? They sound neat.

Wow, we're kinda all over the place.
Thanks all. Wonder why it's so hard to find a sealant that isn't an adhesive, in a tube? If it wasn't such a mess, I just use hot tar, like sailors have been doing for a couple of thousand years or so.

Rich where did you get the plastic covers. They have a name?

Actually, you hinted at it. For product to come in a tube it has to be too flowable to stay in place (you said you wanted to inject it into cracks). So, there must be some mechanism to make it thick:

• Tar stiffens when it cools.
• Butyl is already stiff and is packaged as tape.
• Caulk in a tube cures (adhering is a nearly unavoidable side effect).
• Dolphinite comes in a can.It also dries out in small applications.

Folks have listed some pretty poor adhesives. I think that's all you get.

If he goes with butyl, how does he remove the residue if he changes his mind? Does he need a solvent, or just something like a soft toothbrush?

Butyl depends on the grade. My port lights and hatches I removed and bed in Butyl that is very tacky, almost glue like, a mastic, it stretches and gets webby when pulled. It can be removed by getting a good gob of it in your hand and dabbing the leavings off the surface it is stuck to.

On my motor control panel and things that will be pulled off every so often I use a less tacky butyl tape.

I can't remember the source but here is a picture.
