...In the context of that conversation, I got the impression that "spotface" didn't have much to do with the process of masking, yet that's the only way I've ever heard it used.
So that made me think, "Huh?" *Insert 'me-feeling-dumb' emoticon here*
Thanks in advance for helping me understand...
Hi Chris -
We have more information at our website - http://www.viadon.com - and although there is not a specific "anodizing" link (this is due to the variety of tapes which can be used for it), check out the "Tapes - Lead foil", "Tapes - Aluminum foil", "Tapes for Powder Coating" and "Tapes -...

I admit I am not familiar enough with all of the specifics of anodizing to know exactly what chromic anodizing involves as far as heat and chemicals. However, my company does provide masking tape to a lot of anodizers, and I'd bet that at least a few of them are doing chromic...
Depending on the areas of the part that require masking, some masking is designed to avoid creating the sharp edges, and custom masks can be designed to "feather" the powder as well.
An alternative method (as described before) is to remove the masking prior to curing the powder. This method...
dbooker630 - I'm a Viadon (Dave), but any of the other companies can help you too. Tolber only carries liquid maskants, the rest of us design molded and die cut masking.
Our company designs custom masks for difficult-to-mask areas - we'd be happy to take a look at the part and see if we can help you, or even refer you to a specialized firm if necessary. If we couldn't help you out, they certainly could.
I don't think you'll find a way to reclaim wet spray that is actually practical. I may be wrong about that, and if I am, I've got lots of customers that would certainly be interested!
I think a better solution would be to work towards increasing your line density, depending on whether the...
For the through holes, pull plugs might be a viable option as well, as long as the parts are not more than 1" thick (as most pull plugs are 1" long for handle, 1" masking area). Pull plugs may be oversized above the part diameter by up to 5%-7% - this is often the case in plating situations...
Suggest to your powder coating supplier that they try using flangeless plugs. They are of a ribbed design, and they designed specifically for masking threaded holes for powder coating. That should eliminate the problem.
We carry them (see here: www.viadon.com), but most any other powder...
Silverspeed,
I checked with one of my suppliers, and he couldn't even find a cross-reference to that tape.
Are you looking to match a current tape with the Mystik tape? At the very least, I can hook you up with some samples of some foil/glass tapes (which I can get specs for), though I...
In my completely UN-scientific experiments here using several different kinds of rubber (simply pulling them across Teflon tape), EPDM rubber seems to "hold" the best.
Of course, anyone with more scientific info is welcome to refute (or support) that.
Hope that helps.
I'm probably not the right person to answer this, but I hope this may help explain it. There are many different "flavors" of silicone that can be produced: hard rubber, soft rubber, foam rubber, liquid adhesive, pressure sensitive adhesive, and yes, paint that includes silicone.
If I...
Lead foil tape with natural rubber adhesive is probably the most widely used masking for hard chrome, however, you may also have good luck with 7 mil vinyl tape (that will give you pretty much every color of the rainbow and then some).
We stock and slit both of these kinds of tapes, however...

Sorry about the late reply; Scapa Industrial makes a tape that is an unsupported (no carrier) acrylic adhesive tape that is 5 mils thick, can handle operating temps of -40 to +300 and has a peel adhesion of 290 oz/in. They also make a 2 mil version of the same tape (145 oz/in). Their sales...
Powder coating offers almost limitless color options - very tough, gets heated to 400F for curing (so can handle the 120 easily). Cost varies depending on how you want to powder to perform, as many different blends exist now. Numerous job shops nationwide that could handle 1 part to millions...
Huntress,
Another option might be some of the new UHB and VHB (Ultra High Bond and Very High Bond) adhesives that are used in a number of construction industries (RV's, etc.). These are a form of tape (without the carrier - so it's really just adhesive on a release liner) that is being used...
Have you considered using silicone plugs for the bored surfaces (I'm assuming they're round)? There are a number of different styles of plugs available which may be useful - regular tapered plugs, pull plugs, flangeless plugs, etc. Even silicone caps (which are usually used to cap studs or...
