solubility you choose the ingredients
solubility you choose the ingredients based on whether they do or don’t
based on whether they do or don’t
based on whether they do or don’t dissolve in each other so when the dry

the table the solvent has to fully dissolve both the resin pigments and the

dissolve both the resin pigments and the release agent but when you write on a

whiteboard that solvent is going to
whiteboard that solvent is going to evaporate leaving only the resin pigment
evaporate leaving only the resin pigment
evaporate leaving only the resin pigment and the release agent and this is the

key part the resin pigment has to not dissolve in the release agent so on the
dissolve in the release agent so on the
dissolve in the release agent so on the whiteboard they separate out into two
whiteboard they separate out into two
whiteboard they separate out into two layers just like oil and water the
layers just like oil and water the
layers just like oil and water the release agent is the layer closest to
release agent is the layer closest to
release agent is the layer closest to the board and the resin pigment is on
the board and the resin pigment is on
the board and the resin pigment is on top of that but it does not stick to the
top of that but it does not stick to the
top of that but it does not stick to the board so when you wipe the resin pigment
board so when you wipe the resin pigment
board so when you wipe the resin pigment comes right off and the release agent
comes right off and the release agent

dry erase marker and a permanent marker
dry erase marker and a permanent marker is that the permanent marker does not
is that the permanent marker does not
is that the permanent marker does not have a release agent so here the resin
have a release agent so here the resin
have a release agent so here the resin pigment just sticks to whatever you’re
pigment just sticks to whatever you’re
pigment just sticks to whatever you’re writing on and you cannot get it off
writing on and you cannot get it off
writing on and you cannot get it off without some sort of solvent now what
