Thus, does anyone know what VPI stands for and where I could obtain some of it? If there's a better suggestion on how to store cast bullet molds to prevent rust, I'm all ears so please share your advice and suggestions. Share Share this post on Digg Del. Most folks just spray some oil on them when they have cooled then use some spray on break cleaner to get them ready to cast.
I changed over to Aluminum molds years ago and they just go in a drawer between casting. As far as bullets go, just box them. This paper is impregnated with a vapour phase inhibitor to prevent corrosion. Goods wrapped in VPI Paper will not rust in transit or storage.

What Is Vacuum Pressure Impregnation? The Vacuum Pressure Impregnation Process Sloan specializes in vacuum pressure impregnation, which is more effective than traditional dip-and-bake methods and is better suited to high voltage motors and generators. Curing Finally, the equipment is placed into an oven to cure the resin. The vacuum used in a VPI creates a more solid structure that can withstand: December 9th, by admin.
We pack various parts for our service dept by first wrapping them in VPI paper, then bubble wrap, then packing in a cardboard box. We have various sizes of parts, and hence various sizes of VPI paper to wrap them in.
In our company it has always been the assumption that for the VPI paper to be effective, it should completely enclose the parts, but, from the reading around I have been doing, the corrosion protection comes when the anti corrosive chemicals in the paper get in to the air around the part. The questions I have are: If we used a smaller sheet of paper, so did not get complete enclosure of the part in paper, but are subsequently wrapping in bubble wrap and a cardboard carton, will we then have 'less' corrosion protection?
Or is the level of corrosion protection independent of the amount of paper used? Does the storage of the VPI paper itself, before it is wrapped around our parts also affect the level of corrosion protection given. I assume that 10 year old paper that has been subject to temperature variations will be a lot less effective than a freshly delivered batch. Is this a correct assumption, and if so, are there any recommendations for storage? We buy through a re-seller who doesn't want us to contact the original manufacturer.
The parts in question are sub assemblies of various steels that are spare parts for powertools.
ARMOR WRAP® VCI papers utilize VCI nanotechnology and are essential to keeping your metals protected and corrosion-free for years.
VCI paper and film are treated with engineered chemicals that safely prevent corrosion on protected metals. The chemicals in the VCI or VPI products are volatile. When metals are wrapped or packaged in VCI products the chemicals volatize in the packaging environment and form a protective molecular layer on the surface of the metal.
