Latest Patents

Kerres’s recent patent work focuses on compositions that help industrially sprayed surfaces reflect light.

“Retroreflective Composition for Industrial 3D Spraying of Large Surfaces” describes an ink, coating, or paint formulation containing solvent, spherical glass beads, thickeners, and synthetic pigment flakes. The glass beads have specified particle sizes and refractive properties, and may include a light-reflective coating. The formulation is designed for spraying large surfaces while combining retroreflective performance with controlled composition and application characteristics.

“Organic Solvent-Based Retroreflective Composition for Industrial Spraying” concerns a solvent-based ink, paint, or coating with defined viscosity ranges at different shear rates. Its ingredients include organic solvent, spherical glass beads, thickener, and optional additional components. The specified viscosity behavior is intended to support industrial spraying and the application of retroreflective coatings.
