Mineral Oil & 5200?
 

The question has come up; what effect does mineral oil have over the adhesive qualities of 5200 over time?...:head:

Used 5200 to attach the transducer well to inside of hull...and plan to fill with mineral oil...anybody have any thoughts or past experience w/this??...I guess I'll be in touch w/3M's technical gurus on this one...

Ozzie I do not believe it would have any effect once the 5200 has set up. It could slow or retard full curing in the area of contact if put in place before the cure has set.
It is impervious to many chems and chem agents once the cure has set, I believe for standard 5200 would be at least 24 hours but i would give it 48 to be sure, especially in a damp or high humidity enviroment.

I agree--I do not think that mineral oil will effect 5200 in the least.

As for full cure--I beleive it states 72 hours on the tube.

Willy I agree w/you and Genie Aye...one guy said he had a problem, but admitted he didn't let it fully cure the 72 hrs called for...he fixed the problem w/a quick dry latex sealant by DAPCO...I might give it a coat of that just to be on the safe side...sure won't hurt...

Thanks Guys!!...

5200 full cure time is 7 days. Fast dry is 24 hrs.

Hey Reel? Just a quick question... why are you using the pipe filled with fluid instead of just epoxing the 'ducer to the floor like it is called for by the makers? Is it for ease of removal sometime in the future, or something else?... Thanks..

Destroyer...that's a good question!!...had considered all along would epoxy...then when CB laid out this method, it does leave a second chance if this doesn't work (I think it will)...epoxy one and it's cooked, working or not...over the years I've come to appreciate things that can be undone...

hey reel. I have installed the same transducers that you are talking about. If I remember correctly you are supposed to use GE silicone to install it to the hull. The ones that I have installed specificly say not to use 5200. You can also fill the transducer with ethyl glycol antifreeze if you dont have mineral oil.

Cool... never heard about the antifreeze fill before.. good to know.. :clap:

You can find mineral oil in just about any supermarket in the health section. People take it as a laxitive. Usually about $2.50 a bottle. Besides using it as the liquid in a compass it's also used as the fluid inside a liquid filled sump pump. Very high dielectric strength.

I've used sun tanning oil in a pinch, worls just fine
