Custom Solvent Blending Using the Hansen Solubility Parameters

I wanted to restore an old metal table that has been sitting outside for more than 30 years. The top is discolored and rusty.  This is a perfect chance to teach the principles of solvent blending using the Hansen Solubility Parameters

This video hits the highlights of the process.  The technical details are available upon request. 

I have a newfound respect for videographers.  This video is pretty rough in places, but I did not have the time nor desire to retake the rough scenes. I promise to provide a more detailed blog post in the future that focuses on the solvent blend optimizer.

  1. Nice A/V skills. I did a time lapse movie of an 8 hour experiment at work and sync’d it with an excel chart with a moving time indicator from within powerpoint. It was not easy but super cool and impressed a bunch of the corporate guys.
