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 ?


Morgan O.

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?


Morgan O.


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.
