Re: Does DOW 795 ever cure, bond or dry?

Dow 795 is perfect for through deck chain plate seals as it never truly cures . If using it in a place where someone may step or touch, I found a sprinkling of talc over the out side helped.

PLEASE don't ever use the phrase "DOW 795" in a title again. I haven't checked my stocks in a few weeks and I almost had a stroke.

Not only that - SHE hunts down & buys the boats in her family. I think her husband struck more gold than Sutters Mill there.

From Select Plastics - the largest hatch remanufacturer in the business - temp has to be above 50 F for the entire 21 day cure.

I believe you got some old stock and it will never cure remaining like silly putty forever. I got sold old stock as well for my windows and contacted Dow. They told me never to use 795 beyond its use by date. Oh what fun peeling all that stuff off! The vendor gave me fresh tube and it cured with no problems. Sorry for the bad news.

Just found the Dow specs for the Dow 795 - and now I realize whats happening ---" In totally confined joints (the sealant
requires atmospheric moisture for cure)"
In using this Dow 795 the more is not better- My window situation is because I believed the opposite and pumped as much of this stuff as I could in the joints. Also I think the reason my small test pieces did not bond is because the bead I applied was in the center of the pieces and sitting at the corner of my office desk and since there was no moisture present the silicone did not cure.
I would include the specs in pdf format but I don't know how.
