favorite epoxy with divinycell H80

About to use some divinycell H80 for a hull. Does anyone have a favorite epoxy that seems to work well with the divinycell?

Thanks,
Rob

 

Yes RAKA, but the hull should not be of sandwich construction below waterline.

In my opinion it should not be of foam sw anyway.

But thats my opinion, some others have other ideas........

 

Plenty of good epoxies, and depends on whether you are hand laminating, vac bagging or using the infusion method as to what is really required.

I use a good epoxy in Australia, but you cant get it there (US), so best to source local imho

Thats clearly a comment from someone who is clueless.

You know what they say about opinions........................

 

ive been using west with balsa core, but now need to use foam for this set.
Just wondering if anyone has a preference, and wouldn't mind if it ended up costing less.
I am doing a hand lamination, so a little thicker helps me out.

These are for drysailed racing catamarans, so I wont pay attention to everyone else's thoughts on what is the right or wrong core to use.
thanks,
Rob

 

No, tell us!
Especially about your well established preconceptions which are based on opinions only!

 

You have no idea how many boats I have built or what my history is.
You are pulling numbers out of your arse and are making yourself look foolish.

How many of those have been lightweight composite multihulls?
How much knowledge of these types of vessels do you have?
Do you care to provide us with examples of these lightweight composite multihulls that have solid glass bottoms?

<everybody has one>

Who was talking multihulls here?

Except you of course

 

Perhaps you should get down off your pedestal and read the post before looking an even greater fool

Now, how much lightweight composite multi experience have you got?
Examples please, especially the ones with solid glass bottoms.

Perhaps you should stick to your steel dinosaur's

 

Oops,

I must confess I missed that.

Your last comment shows pretty clear, that it is not worth to try talking serious business with you. And it shows who is on a pedestal. (own goal)
Your stupid preconception is so well established, that I do not waste my time on you.

My so named steel dinosaurs are made of almost every taste of advanced composites, steel is not amongst them.

over and out........

 

Pays to look before gobbing off

My stupid preconception?
What, like the stupid preconception of yours that I have only built one boat?
like the stupid preconception that boat bottoms shall not be cored?

Really?
Strange that you rejected a composite build then isnt it?

What is this advanced composite you speak of ? Solid choppies and poly?

And while I'm here, how old are you and how is it possible to have built several thousand boats?

I call ******** on that.

See ya...............

 

You probably already have the Divinycell on the shelf, but when you have some time, see if you can get your hands on some Parabeam 3D fabric to play with. Incredibly rigid (I used it with vinylester) and light. Best of all, there's a firm connection between inner and outer 'glass layers, unlike foam.

(I stole the pic off the interwebs--I don't have any connection to the manufacturers or distributors of this stuff. In fact, they shun me when I email them.)

 

very cool. I have used some mat products for repair. I would like to know how much resin it absorbs
Rob

 

In general the same weight as the glass is. In Handlayup add some 10 - 20%, depending on your skills.

 

Very little. If you get it too wet, it fills the inside with resin and you lose the whole effect. You just need enough to wet the fibers.

I learned to use waxed resin with the stuff so it would cure on the inside.

 

Oops

seems I misunderstood the question as being related to the mat. not the Parabeam which I have not used yet.
