I understand that someone out there has found a terrific coating for metal mounts that involves a powder and minimal heat and no fumes and passed Oddy tests, but I can't find it in these discussions. Can someone please direct me to this material and share your experiences with it? It sounds potentially wonderful!
I normally use Krylon Crystal Clear or B72 in xylene (seems more flexible and less bubbly than with other solvents), but am interested in other coatings you all might be using as well.
Thanks much, Shelly
We have been using this coating a lot. We can paint the mount with acrylic paint and then heat it with a heat gun and then ether dip it into the powder or sprinkle on the mount. Then we heat the mount again to get the plastic to flow out. Sometimes we dip it twice if we want a thicker coating. The coating is design to make light bulbs shatter proof. So it is clear and UV resistant. The coating is glossy but you can make it duller if touch it while it is still warm. You also can sand it to dull it down. The mount is usable as soon as it cools. It is great for armor and swords that can cut through other barriers. I also coat my pinning pliers with it to make them safer around objects. We also use it in black.
I would like to thank Mac at the Getty for ODDY testing it for us!!!!

RE: [mountmaking-forum] Re: Mount Coatings Wow! This sounds great. Where do you get it, how does it come, how expensive? How hot do have to get the object that you are applying it to?
You can get it by following this link:
It comes in a 44 lb box for $286. A 44 lb box would last you about 100 years. So it might make sense for someone like Benchmark to sell it in smaller quantities. You have heat the mount to about 230C. Don't heat the mount high enough to discolor the acrylic paint.
Thank you so much for the hot tip. I wonder about procedure... the last bit of acrylic we use (after primer and base-coat) is a brush painted faux coat. Then we typically apply the padding or dip-coat b-72. Have you been successful with the same heating and sprinkling technique over hand painted acrylic?
Philip Brutz 5/1/08 Yes, that is what is so cool about this coating is that we can paint out the mount, heat it, dip it, and install it. Philip
