Yes, absolutely. A number of companies make PTFE "dry lubricants" and coatings using Vertrel® as the carrying agent. These are normally applied in a dipping process. These processes work
particularly well with Vertrel® because Vertrel® has some capability to dissolve PTFE and the densities of the material are similar to each other. Coatings produced with Vertrel® will have superior lubricity to coatings produced with HCFC-141b carrying agents, for example, because of the intrinsically closer match chemically between the Vertrel® and the PTFE lubricant. The end result is a PTFE coating that is exceptionally smooth, free of runs and drips, and highly cost-effective.
In the photo at right, two coatings are compared. On the left, a 2% concentration of PTFE was applied with HCFC-141b as the carrying agent. On the right, the PTFE was applied in the same dipping process, but with Vertrel® as the carrying agent. The difference is striking.
The handling of the dipping process is simplified, as well, with Vertrel® because the material stays in suspension better than with the lighter carrying agents. This improves quality and reduces rework while simplifying the need to constantly agitate the dipping solution.
