Title: Larry G. Weidman: Innovator in Marine Coatings
Introduction
Larry G. Weidman is a notable inventor based in Fort Myers, FL (US). He holds 2 patents that focus on advanced coatings for marine applications. His work emphasizes environmentally safe solutions that address the challenges of marine growth and acidic conditions.
Latest Patents
Weidman's latest patents include innovative formulations for high concentration acid resistant coatings. These improved polyamide-based compositions are specifically designed for plasma-spray applications on surfaces exposed to acidic environments. The formulations consist of polyvinylidene fluoride, a polyamide such as Nylon 11, and a compatible adhesive like a nylon terpolymer adhesive.
Another significant patent is for an apparatus and method for applying plasma flame sprayed polymers. This invention provides an environmentally safe protective coating for marine surfaces, particularly boat hulls. It is formulated to resist marine growth while minimizing the release of toxic antifoulants into the environment. The coatings are made from powdered mixtures that include Nylon 11, an inorganic porous carrier like carbon black, and an antifoulant such as tributyltin fluoride. The application process involves creating a supersonic gas stream, heating it through an electric arc to convert part of it to plasma, and injecting the powdered mixture into the heated stream for effective coating.
