hi

today i saw floor polish at a local shop.
i remembered the post of using it as etch resist. (in inkjet).
so i thought i may try the printing with it (facing problems with hpgl file generation to plot etc,
etc.)

it should be acrylic floor polish be used but i have no idea if this is one.
since several years it seems no longer required by law to state the main ingredients at the label of a
bottle.
i don't like this. i believe in the past on nearly every product stood what is in there, at least the
main ingredients. maybe they don't want to tell it to the competitors but i think they can find it out
anyways.
this would also be important for appropriate medical treatment if swallowed accidently.

it was a cheap small can, only 5 eur.

the brand is BONA Parkett-Polish.


how can i determine if it is acrylic??

it smells like transparent water based laquer. (i did this guess in a previos post and seems to be
right).
i think it is diluted water thinable laquer but very diluted.

it has a very hollow milky- white appearance, but more transparent.

if anyone can tell me if this is the right stuff??



another question about ammonia:

this is the stuff with the strong smell?
who strong should be a ammonia / water mix to use as cleaner (%)?.

this should be able to clean the dried polish?


if anyone may help it would be fine...

i have found having a inkjet which would be very easy to convert to use pcb material but have no ink
cartridge. this is a hp with head in cartridge (good if clogged and not repairable). i have to get a
cartridge before i can try.


someone mentioned schellac could be also used.
i think if anyone can get this stuff to pass through a printer head it may also be possible to use
colophonium. this would give a ready fluxed surface for soldering and protection against oxygen on the
tracks. but i don't believe it would work (but it's similar to schellac)

any thoughts welcome like ever....
