hi
i am not sure if it is the best long-durability coat.
do you coat it before sodering and then not again?
i would fear the coat may be interupted near the soldering joints.
if i want to make a board that last forever i would clean it on the solder
side after soldering
and then paint it with clear laquer.
do you have long term experience with this? does it really last so long?
i once dissolved it in acetone because i had no alcohol left. (i use ethyl
alcohol).
it worked too but it dried maybe too quick. also it was not the shiny coat
you get from
alcohol solved resin. how is this with nitrocelulose thinner? shiny or
matt?
- at the moment i am not sure what nitrocelulose thinner is. i wonder if it
simply is "nitro thinner" as it is called here or something else.
you may have read when i suggested to use colophony/resin as resist in
inkjet/plotter.
the problem is that it is a sticky mess when you dissolve it in ethyl
alcohol.
i treid how it resists etchant and the results are not bad but i have no
idea
how to make a "laquer" of it.
