High-end solid wood furniture (rosewood/oak/walnut/teak) scratch-resistant, heat-resistant and anti-fouling nano waterborne coating builds a transparent ceramic coating in a waterborne polyurethane/acrylic matrix (VOC 10 MPa·m1/2—resisting brittle cracking)—pencil hardness 9H (traditional PU paint 2–3H, NC nitrocellulose paint 1–2H), dry film thickness 90% (preserving natural wood grain and color—Delta E RMB 50,000/piece) with extreme requirements on coating transparency/hardness/environmental friendliness makes nano waterborne ceramic coating the fastest-growing segment (annual growth >15%). Complies with EN 71-3 (toy safety—specific element migration—surface safety of wooden furniture in contact with children), GB/T 23999-2022 "Waterborne Wood Coatings for Interior Decoration and Refurbishment", and GB/T 35602-2017 "Green Product Evaluation Coatings".
