Alternative for 5200/4300

[Alaskan Sea-Duction]

For those that don't know you can get 3M 5200 at Home Depot for about $17. The problem I have with these 3M products is once you open the tube, that's it. One-time use. This is the small tube with the screw on cap. I called 3M and they told me it was a one time use. This stuff isn't cheap when all you need is a dab.

I know there are also other alternatives that TF folks use, but you pay premium price.

But I may have found a good, reasonably priced product, about $9. One thing to be aware of is it says "fast cure" and it is. It also has a good cap on it.

Just sharing. I have no commercial interest in these products.

That's wonderful ASD.
I always keep a small tube of Life Caulk for that reason.
Any info on the Locktite re UV resistance, adhesion ect?

Just started using a new to the US product called Rescue Bond. It's from my friend who owns Rescue Tape, and he's really excited about this product. We're kind of "testing" it around the boat, even though it's been used extensively in Europe and elsewhere. So far we've rebed a deck prism on the foredeck (which doesn't leak for the first time in years), filled holes in the upper deck (no leaks again) and fixed peeling non-skid strips on the fly bridge ladder. So far so good. We'll keep using it on more things we find.

Oh, the cool thing is once opened the tube is good up to 6-months.

I have been buying extra nozzles for 5200 . I just let it dry in the nozzle and screw a new one on the next time . Still it's not cheap but it has been working lately .

The information on Amazon says it can be painted with any water based paint. There aren't many people using water based paints on their boats, so I guess if your going to paint afterwards you will need to use something different.

I noticed Active Captain promoting the Rescue Bond XL...

Has anyone been able to find a MSDS to see what the "Hybrid" really is?

I keep a small tube of 5200 or 4300 with the screw on cap in my freezer. It lasts for ever in the freezer. My last little tube was still useable after 10 months. I probably used it about 4 times in the interim. Just recap it and back in the freezer. I have not tried freezing a large tbe, but then again, I do not need it very often so I generally do not buy a large tube.

So I thought I'd give Rescue Bond a try. It has some great claims on their promo material, but what is missing is any reference to cure times other than "Rapid Cure." There is no suggestions for working time, set time or cure time on the container.

I wanted to secure a small, plastic storage box on my upper deck, behind the pilot house, but wanted to try something other than drilling into the deck. Since Rescue Bond claims to stick to anything, I used it to "glue" down a couple of small blocks of Starboard which I would use to screw in some brackets for the box. I did this two days ago but the Rescue Bond has only "cured" a little bit around the edges. Weather has been dry, day temps in the 60s(F) down to the mid-40s at night. Can anyone with experience with this product give me a hint as to how long it will take for adhesion?

Thanks,

Presently becoming a fan of butyl tape. 95% of the things I've used 5200 on and 100% of 4200 have plenty of mechanical strength / bond already.

OK - I just gave up on Rescue Bond.

I went back to the boat this afternoon and, more than 48 hours since applying, the Rescue Bond had not set up. The Starboard blocks were easily lifted from the deck and the Rescue Bond was still so liquid I was able to clean it off with a paper towel, then used a solvent to get the residue off.

Don't know what went wrong, but it didn't work at all -- back to 4200...

Anything you remove to re bed will probably need re bedding again.

Dolfinite is probably the easiest to R&R , it is not a glue .

Some early TT need to re bed every thru deck fitting and PH windows every 5-8 years , so it pays to be EZ on your self .

I would contact the manufacturer. I'm sure they would investigate what went wrong. The power of social media is of great concern to small companies.

What went wrong is that starboard i dam near impossible to glue. I would say this is not the sealers fault. To successfully glue starboard a special adhesive is required.

True, but whether it bonded to the starboard or not, it should have still set.

First, it's important to understand that these products are not all the same and it's important to use the right product for the purpose. Some are sealants, some are adhesives, some are a combination of both, some are intended to be permanent and some are intended to be removable.

Second, There are tried and proven products and there are "new" products. There are times and places where using a "new" product is fine; if it fails, you can remove it and use something else. There are other times where the application is more critical and a proven product might be a wiser choice.

There are LOTS of good adhesives/sealants for marine use. 5200 is the gold standard for mounting things like thru hulls where one cannot afford failure.

A few products that work well (both dry somewhat flexible)

West Systems G Flex 655 epoxy, great for for plastic or wood or metals and dissimilar materials. 75 Shore D durometer, Cure 45min. Workable cure 7 hrs. Great for waterproof seal, where there might be some flexing.

3M DP8010 Scotchweld similar to above, but more expensive, shelf life only 6 mo. Shore D 55 to 60, if you need more flex.

I've had no problem sealing up the tube of 5200 and using again, but over time, it will harden.

Yes, I also freeze all polyurethane cartridge tubes. They work great after a thawing, no hardening. I put mine in a plastic bag, then into the garage freezer. A freezer halts the curing reaction with moisture, being a freezer, the air becomes dry. This works with Loctite PL polyurethane products.

Many folks will argue that 5200 is a poor choice for thru hulls because it is permanent and you may have to remove them at some point. 4200 may be a better choice.

A thru hull will have a nut on the inside to keep it from falling out. Adhesion is not important but sealing is.

According to their published specs, this is a polyether which is the same type of sealant that 3M uv4000 is. Since Uv4000 is about half the strength of 5200, is a much faster cure and it does not yellow when exposed to UV, it's pretty much my go to sealant except when I Need 5200's properties. So this sounds like it could be a alternative to UV4000.

I do not know if this helps, but for well over 20 years, we have been using moisture cured polyurethane sealants from TREMCO and will never look back.. I learned the science behind them & avoided all the "marine hype" and associated "marine costs" about what they are all about way back.. As to 3M 5200 & 4200, great products if you want to pay 4+X the cost for the same or better product without the word "MARINE" as part of the marketing scheme..

But, then again we use 100's of tubes per year so to average "Joe boater", maybe that does not matter.. .
