[Rhodes22-list] To Stan @ GBI

[Roger Pihlaja]

Stan,

Gee, I hadn't considered eliminating the glass fiber reinforcing, but why
not?  A foam composite polymer hull could be structurally rigid, much more
sound deadening, and any issues with internal condensation would go away!
Isotec makes spray-in-place polyurethane foam products as well, but I don't
know if they've considered them for use in an application in quite the
manner you are proposing.  Why do you think there would be a problem
fabricating a 22 foot sailboat with this technique?

Isotec is such a small company that it sells both thru direct sales as well
as thru contract agent middle men.

Roger

visited Futura in St. Louis twice looking into their idea to make products
with structural resins with no glass needed.  Never did pin them down
whether they thought it would work with a 22 foot size boat.  What they did
show me was interesting and allowed items to be popped out of a mold many
times a day.  They put in a urethane gel coat - then their structural
resin - then a foam they made up and then a final structural resin end coat.
It took only one skilled gun man and a second man to hold the hoses.  Fast
and nice stuff.

and we could end up buying it direct, that would be interesting - so get the
job.

the urethanes business.  I'm writing to you to let you know about a series
of Isotec products intended for the recreational marine industry.  The

to produce product or expand your operations?  If so, then you might be
particularly interested in Isotec's ACRYLOBOND-EXP product, a two-component
polyurethane designed to be an environmentally friendly, drop-in replacement
for the polyester resins currently used.  As a polyurethane, I would imagine
the UV resistance, impact and abrasion resistance, flexibility & resistance
to crazing, & resistance to osmotic blistering would also be much better.
What would you think about polyurethane/glass fiber reinforced Rhodes 22's?

When I saw the spec sheet for this product, I immediately though of you.
