Hi Steve,
We work with this material all the time. It is one of only three we use on
all our space products.
It is quite different from Conothane 1155. CE1155 is hard, rigid material
curing to a smooth shiny surface. Arathane (New name, was Uralane 5750) on
the other hand has much longer cure and remains "soft" compliant almost like
a thin layer of RTV. It has a glass transition temperature of -60 deg. C.
That is the value of it for us, we never have to worry about breaking glass
diodes at low (-34 deg. F.) temperatures. CE1155 too thick will definitely
break the little glass diodes. The down side is that the cured Arathane
acts like fly paper and traps dust and fingerprints. It will not rinse
clean like the CE1155. Coated components can be reworked by either
"peeling" the coating of "melting through it to re-solder a part. There are
other tricks too. The activator is moisture sensitive and can go bad if not
stored properly. If the material is not mixed properly and does not cure,
it is a nightmare to remove. Over-all the added effort and risk is still
better than a system failure later with a cracked diode.
I think I have a link for properties I will round up.

Subject: [TN] Uralane / Arathane 5750 Conformal Coating...
Afternoon All!
I've been trying to find (without much success), and Technical datasheet for
Uralane / Arathane 5750 conformal coating...could someone point me in the
right direction?
Have any of you worked with this material? Is it any different than say, a
Conap CE-1155 two-part urethane coating?
Thanks in advance!
Kind regards,
