We understand the problem of trying to coat over RTV. We have seen the same problem with acrylic and urethane coatings not wanting to stick to RTV. Some acrylics seem to be worse than urethane. Since this is a new product, may be you could pot your

Common RTV does out-gas causing corrosion. NASA allows use of non/low-out-gassing RTV. Try the following companies: * Ablestik Electronic: Materials, 20021 Susana Road, Rancho Dominguez, California 90221 U.S.A., 310-764.4600, F 310-764-2545 * Arlon

Dear Sir, Please clarify my doubt... What will happened if acrylic conformal coating is mixed with poly urathane conformal coating and mixing of this composition is used to apply for electronic PCBs Thanks & Regards, Raghuveer S.

What happens when you rework those non-coated areas? Please list your rework steps Br, davef

Yeh due to the solvents in the coatings im guessing there is a health and safety risk. Solvent stripping is a lengthy process for the coatings we use and usually means submerging the whole board so not local to the rework. We have a booth with ioni

Not entirely clear on your question. We don't coat any of our hardware (assemblies are coated prior to hardware installation), so if coating needs to be reworked after this, then hardware removal is needed.

A couple of things to try as I just went through this myself. Checkout this link for pointers on plasma cleaning... http://www.nordson.com/~/media/Files/Nordson/march/Papers/The-Effects-of-Plasma-Treatment-Prior-to-Conformal-Coating-NordsonMARCH.p

Hey Phil, i'm just curious what your rework processes are for your hardware after conformal coating is applied (if any). I'm interested in conformal coating as our hardware can be exposed to moisture rich environments at customer sites but to my kno
