Latest Patents

One of his latest patents is titled "Coatings for pelletized thermoplastic pavement marking compositions." This invention provides a coating for pelletized thermoplastic road marking material, incorporating waxes, silica compounds, and inorganic compounds on the surface of the thermoplastic pellet. The process involves mixing a binder mixture with a filler mixture, heating the ingredients into a homogeneous molten mixture, and extruding it. The extruded material is then cooled, cut into individual pellets, and coated to prevent clumping while enhancing flowability and lowering melting point properties. Preferred coatings include micronized polyethylene wax, silicates, silanes, silicones, siliconates, fluoropolymers, calcium carbonate, and zeolite.

Another significant patent is "Thermoplastic pavement marking composition and method." This invention outlines a composition suitable for use as a road marking substance. The method includes mixing a binder mixture with a filler mixture, heating the ingredients into a homogeneous molten mixture, and extruding it. The extruded material is cooled, cut into pellets, coated with an anti-clumping coating, and packaged for in situ road marking applications. The binder can be alkyd-based or hydrocarbon-based, incorporating rosin resins, wax, and a plasticizer, with a hydrocarbon resin added for the hydrocarbon-based binder. The filler consists of titanium dioxide, a pigment if necessary, and ground calcium carbonate.
