Gluvit

[shadowrider]

I am replacing the floor in my 71' 16' Starcraft SS. This was going to be a quick floor job, but is escalating into more work as I read more, and see others boats nicely restored. After reading several posts about gluvit, I am apprensive about using it. The boat has no leaks. My concern is that it will do no good on rivets above stringers. Topcoating a double layer of aluminum will not seal a leak under the stringer, so I thought I would save gluvit for a useful purpose. Also it will run off of any seam it is applied to, unless the seam is level. I can not roll the boat to get it level, too heavy with motor attached. I am trying to get it back on the water asap as salmon season is in full swing. I will apply it to all rivets below water line that are through single thickness inside hull.
I was thinking about using gluvit on the new ab marine ply floor instead of wasting it on rivet seams at an angle where it will run off. I have a quart of it, originally thinking I would just do rivets, it is supposed to cover 25-30 square feet, that is only 5'x5', which is about 1/3 of the floor, so, I am wondering if it will cover more when applied to plywood ? Seems like it would be easier and faster than going the poly resin/glass route. Is there a simple method of keeping gluvit from running away from desired area ?
Has any one used it on plywood , if so did it go furter than 25-30 sqft ? Thanks for reading this long winded post, and any replys.

Re: Gluvit

Well, I just finished applying Gluvit to the rivets, and I must say my concerns were invalid. Product had a long pot life, I finished all the rivets then coated one side of a floor section. This was all done with half a can ( 2lb ). I accurately measured the resin in the can, there was exactly 19 oz of resin. I measured out 9.5 ounces and added 2 ounces of catalist for the 5:1 ratio.
It did run away from the rivets, but that's part of the game. I would use it again for sure.

Re: Gluvit

Great product, glad it worked for ya

I do think it's overkill to use gluvit on wood. Regular two-part resin is cheaper, since gluvit is designed to use on bare metal is has zinc chromate mixed in it which is pricy.

Not bad to use on wood, just costs a bit more is all.

You probably noticed that if you let the gluvit sit it will thicken, and not run as much downhill.

Good peace of mind to know the rivets are sealed well.

Post up some photos of this boat

Where did you get this bit of information?

Re: Gluvit

Chemical composition of Gluvit straight from their site.


This is the resin....

Chemical Name	CAS#	Ingredient Percent
Bisphenol A diglycidyl ether resin	25068-38-6	30 - 60 by weight
Crystalline silica	14808-60-7	30 - 60 by weight
Butyl glycidyl ether	2426-08-6	1 - 5 by weight
Diacetone Alcohol	123-42-2	1 - 5 by weight
Heloxy modifier 7	68609-96-1	5 - 10 by weight
Microcrystalline silica	1317-95-9	1 - 5 by weight

This is the Hardener

SECTION 2 - COMPOSITION/INFORMATION ON INGREDIENTS

---

Chemical Name	CAS#	Ingredient Percent
2,4,6-Tris (Dimethylaminomethyl)phenol	90-72-2	5 - 10 by weight
Trade secret.	N/A	30 - 60 by weight
Polyoxypropylenediamine	9046-10-0	30 - 60 by weight
Phenol, 4,4'-(1-methylethylidene)bis-	80-05-7	1 - 5 by weight
Tetraethylenepentamine	112-57-2	1 - 5 by weight

I guess maybe their Trade Secret could be the Zinc Chromate. Not sure.

Re: Gluvit

I looked at the MSDS too, and all of the info they put out, nothing mentions Z/C being an ingredient. I think was more of an assumption by some since it's used on aluminum so often.

I read it here on the forums a while back, and since it does have a greenish tint to it I believed it to be true.

Nice boat Shadow, I bet you will love the jet drive on the rivers

I remember that being stated, but I think it was just an assumption on that person's part based on no facts. In the epoxy world I have never heard of adding ZC to epoxy to help with the bond, and bonding to aluminum is discussed frequently.

Good info, much appreciated. Given your experience I have no doubts that you are correct.

Thanks for the clarification Ondarvr

Re: Gluvit

I don't claim to know all that much about epoxy, so anything is possible, it's just that I've never heard people that do know epoxy well discuss ZC.

Re: Gluvit

The boat has no leaks.

Im no Gluvit man .. Im a Glass man .

Use the materials for what its intended for. Resins for alum .. or Resins for wood/glass ..

YD.

PS. You dont have to apply resin as soon as you mix it. Times I will wait until its "kicking" .. then apply ..

Re: Gluvit

I was afraid of it kicking before I was done. It turned out fine in my opinion. I am coating the plywood with west systems epoxy.
