I'm glad you enjoyed the article. This technology is truly exciting and we expect it will bring tremendous value to applicators and asset owners in terms of ease of use and corrosion protection.

This could be great as a new bathtub paint. We currently make a 2 pack product. Packaging improvements alone could save money. How do we obtain a starting formulation?

Unfortunately, until now, efforts to produce one-pack epoxy coatings based on current ketimine technology have not been successful. It is very difficult to produce formulated coatings that are completely free of water, and even the slight traces of water adsorbed on pigments or picked up from ambient air contact during processing are enough to cause instability and an impractically short shelf life, especially with higher solids (> 60 percent by volume) coatings. The above statement is from the article. Have the problems of instability and very short pot life resolved? and How?
