Title: acrylic resin electrodeposition
Post by: chaos_sniper on June 04, 2014, 07:45:21 PM

hello everyone i am new to this forum and i need your help
sorry if i am posting this in the wrong section.

i am trying to do some electrocoating using acrylic resin. after some researches i tried to use some cationic acrylic to deposit on the cathode. problem is the resin gets deposited on the anode.
for refrence i tired some neutral acrylic resin that gets also deposited on the anode.

if anyone could explain why. i am open to all suggestion.

ps : i don't have the molucular formulas of both resins but the cationic one should be similar to this

What is the deposition process? If it involves oxidation, resin will be always deposited on the anode.

thanks for the reply
the electrodeposition was supposed to involve reduction since its a cationic resin and neutral resin wasn't supposed to be deposited. that being said both are deposited on the anode.
since both of them are copolymers i suspect that the monomere (acrylic) that both share is the cause
and to be precise i think its the carbonyl group that gets oxyded
