Need rubberized dip coating for pressure transducer

1996

I am in need of a rubberized dip coating for a small electronic pressure transducer. The device is .020 inches thick by .5 inches in diameter. The coating should be colored and leave approx. .020 inch coating on the transducer after it dries. This must be accomplished with one dipping. I have used solvent based coating before, but, this required two to three coatings before the required thickness was obtained.

If anyone could shed some light in this area for me, I would greatly appreciate it.

Thank you for your time;

Is there a reason that plastisol coating (such as you sometimes see on pliers, as well as on plating racks) isn't satisfactory, Ed? The normal build in a single dip is in the range you are speaking of. But the temperature resistance is only about 160 °F.

As far as single-dip is concerned, remember the primary rule of metal finishing: cleaning/prepping is almost always more important than the finishing process itself, and is the source of the overwhelming majority of problems. So be wary of any proposition that claims that something is not only a good coating, but requires no prep.

Have you tried Tolber's xp2000. You might get .020 in one dip if you play with the amount of solvent. If you use the optional 140 F drying it becomes very tough like plastisol.
