Overview

PolyGone™ stripping agents are unique formulations that remove polysulfide (PRC) and silicone RTV sealants from metal, ceramic, and some plastic substrates. The top polysulfide producers include PRC DeSoto (now PPG), AC Tech, and Flamemaster. The top silicone producers are GE, Dow, and Wacker. Both polysulfide (polysulphide) and silicone RTV are difficult to remove completely since they actually bond into surface/substrate.

The typically, sealant removal method requires scraping that results in damaging the substrate. There are also products that try to "disslove" the sealants but due to their inertness, this does not work. PolyGone however, reacts with the polymers chemically and breaks them down so they can be rinsed away without damage to the surface/substrate. This offers significant advantages over other removal methods. PolyGone emulsifiers are specialty blended chemistries that wet and penetrate the polymer and relatively quickly emulsify it. This emulsification prevents redeposition of the reaction by-products and allow for water rinsing.

The polysulfide (polysulphide) sealant remover is also available as a gel for use in vertical, inverted and non-immersion applications. PolyGone is effective at removing silicone RTV and polysulfide (polysulphide) sealants at room temperature, are fast acting and environmentally friendly as opposed to regularly used solvents. PolyGone is currently being used by several MRO organizations as a sealant remover.

Available in both liquid or gel.

Probably the most pleasant part of dealing with scraping old ProSeal was having this product. It softens old sealant very quick with a few applications and with the help of some easy scraping. Good way to remove sealant from covers and hatches.

This stuff is amazing! Used it to strip a tank on my Mooney. It’s a lot of work but the gel formula is awesome for keeping it where it needs to be.

This stuff works very well especially once you learn how to use it. If you are resealing tanks or in my case removing sealant from the wet wing. Mooney. It will have a few layers of sealant. I removed each layer one at a time by scraping. it still works well. Its also a great paint remover lol.

This stuff works. I used it to remove PPG1422 and the sealant used by Woodstock (probably Chemseal). The PPG failed after only 5 months. Let the Polygone sit for a few hours, then use a plastic scrapper. Even works in tight areas like around rivets.

Works well and I recommend using the Gel for vertical surfaces. Use caution this will discolor paint very quickly and make sure any run off doesn’t go where you don’t want to remove sealant.

Anyone having to reseal a fuel tank that has been sealed and resealed prior this is a must use. Works well but does take a lot of patience for areas with large amounts of sealant to be removed. I highly recommend using this as the initial application then after wiping out the initial goo come back over it with the non-gel formula and a paint brush to help remove additional sealant that was not fully de solved. Then repeat. Use caution this product will discolor pain so I recommend having a wet rag handy incase there’s any splash or inadvertent drips on painted surfaces.
