Title: Hannu K Pennanen: Innovator in Coating Technologies
Introduction
Hannu K Pennanen is a notable inventor based in Elk Grove, IL (US). He has made significant contributions to the field of coating technologies, holding 2 patents that showcase his innovative approach to creating advanced coating compositions.
Latest Patents
His latest patents include "Pigmented, corrosion resistant, thermosetting coating compositions" and "Pigmented, antioxidant-containing solution coating compositions." The first patent describes a pigmented, thermosetting organic solvent solution coating composition that offers improved resistance to acid rain. This composition combines a resinous polyepoxide, a phenoplast resin cross-linking agent, a phosphoric acid ester catalyst, a chromium-containing pigment for corrosion resistance, and a clay that can fix phosphate. The application process involves baking the prime coating to remove solvents while retaining the phosphoric acid, followed by a topcoat application and further baking to cure the first coating.
The second patent focuses on pigmented coating solutions that enhance resistance to ultraviolet radiation-induced auto-oxidation. These solutions contain an aromatic hydrocarbon solvent with a polysulfide or polydisulfide derivative that has terminal -SH groups. This derivative is reacted with a monofunctional reactant to create a nonreactive derivative. The polar polymeric binder in the solvent degrades through a photo-oxidative mechanism, leading to a stratified coating that protects the surface of the cured film.
