Peelable Maskant prior to Electroless Nickel Plating (Trike Elimination)




Q. I work for an aerospace company in MFD department. I have been searching for some effective peelable maskant prior to ENP for a long time. Currently my company uses Turco maskant which is very difficult to remove. We use many tonnes of Trichloroethylene every year just to remove this agent. I believe that effective peelable lacquer would cut significantly our Trike consumption and allow us to face emerging EU legislation (Solvent Emission Directive) and safe thousands of pounds on new cleaning chemistry and equipment.
I would be very grateful for help.
Thank you.

A. You might try soaking the part in very hot water for a few minutes. This tends to make the maskant very pliable and you might be able to peel most of it off if it is on machined areas. if it is on sand cast, forget it.
You might also try using aluminum foil tape underneath the maskant, looking for a majority coverage, if not all of it.
What is your part?

Q. Thank you for your response. The parts which we cover with maskant are mainly manifolds. The surface of manifold is not flat therefore the maskant gets into holes. It is a big pain to clean the manifolds after ENP. We have to soak the parts for whole night in hot trike degreaser in order to dissolve "Turco" maskant. Therefore our trichloroethylene needs to be replaced frequently what cost us a fortune.
