I would be surprised if this product is still available, especially in
it's original form. As others previously stated, it was rosin in solvent.
The problem with the original product is it required either solvent or
semi-aqueous cleaning after soldering. In today's world of no clean
fluxes, this product would not work. Perhaps they have formulated a no
clean version.

Re: [TN] Someone knows SEAL BRITE COATING?
A blast from the past.
Sealbrite was a Lonco product, a solution of rosin in solvent that was
effectively a simple varnish. Air or oven dried. Worked OK.
Alpha Metals had equivalent products Alpha [2301 2302 etc] which aped it
reasonably well. What happened when everything, including Enthone and
their
products, became Cookson I don't know. Most likely these simple materials
were let go in favour of Enthone's modern OSPs.

Hello All,
Does anyone help input something about surface finish SEAL BRITE COATING?
I
got a talk with pcb fab shop today and I was told that there was SEAL
BRITE
COATING available for pcb surface treatment. I know nothing about such
surface finish and I'm quite curious. Thank you.
