Epoxi is widly spread...

But, sometimes other traits are wished for. Are there any marine performance
(for wood, plastic, ,metalls) glues that (compared to epoxi) are more...

a) elastic?

b) low density?

c) as epoxi but 1 komponent?

d) how is epoxi lowest density achived ?

What are you trying to bond? There are many other waterproof adhesives
and sealants, but in order to make a recommendation, knowing the
application is important.

The list is so long that you wouldn't like to read it. That's why I asked
about which works.

To glue:
Everything from stainless steel (mast pod) = soft foam (seat cushens)

epoxy and rescorcinol are strongest and "waterproof", others are "water
resistent" but have been used on boats. you can find information on
adhesives in "Do It Youself" books at the public library. I've used both
"plastic resin" (dry powder mixed with water, dries rigid) and
polyurethane (the kind squeezed out of a tube with a caulking gun) with
wood screws to build small boats.

there are different kinds of epoxy with various characteristics.
they would be described on the seller's websites.

I don't think you can get away from mixing the stuff, or from the
unhealthy side effects. You should wear gloves when applying and a
mask when sanding.

Google asked if I ment resorcinol ?

Yes, and Pete C mentions Sika (silicone marine glues and sealants) That's
three. Yipeee! ;o)

Especially gluing foams and keeping the weight down is an issue. It's
somwhat stupid, in my oppinion to foam with epoxy.

Almost like shooting mosqitos whith a cannon. Tips still appreciated!


Greetings to all constructive builders!

Hi,

Try Sika 252 or 221, etc...

cheers,
Pete.

I rely on three main adhesive/sealants Epoxy(with various fillers)
3M5200(CALLED A SEALANT BUT HAS GREAT ADHESIVE QUALITIES) and a product
called MArine GOOP (this stuff looks like that worthless silicon rubber
product, but is nearly as strong as 3M5200 but more elastic)

As for adhesision to various materials, if the adhesive is recommended
for that material then the limiting factor becomes surface preparation.
Bad or no preparation and ANY substance will fail.

Which epoxy fillers do yo like the most?

For 'glueing' I generally use a microfiber (like Wests' or similer), for
filling/fairing either silica or microfiber or in some cases the two
mixed 50/50. Silica HAS LESS STRENGTH BUT SANDS EASIER THAN THE
MICROFIBER(damn cap key) I do not like the micro balloon as it leaks and
is very permeable, but it sands really really easygrin

Has any of you tried filling epoxy with the ~4-5mm EPS balls?

It's not strong compared to GRP but it must be many times stronger then a
70Kg/m3 foam.
