Patent No. EP4074782 (titled "Method Of Applying A Solvent-Borne Coating Composition To A Substrate Utilizing A High Transfer Efficiency Applicator To Form A Coating Layer Thereon") was filed by Axalta Coating Systems on Apr 12, 2022. The application was issued on Mar 20, 2024.
Patent Summary
Automotive inkjet coating using polyurea crystals to stop paint from sagging on vertical surfaces while keeping the paint fluid enough for precise nozzle printing. Conventional rheology modifiers are too thick, causing visible lines and poor flow, but these crystals act as tiny solid particles that hold the paint in place without blocking the nozzles. The formula mixes acrylic or polyester resins with melamine cross-linkers and optional pigments, adding 0.1 to 4% of the crystal agent. This allows the paint to be applied in thin lines that overlap smoothly, ensuring a uniform 30-micron layer that resists sagging at 45 degrees while remaining free of defects like orange peel or distinct lines.
