Surface scratches not only affect the appearance, but may also damage product functions and shorten service life. Traditional coatings are often vulnerable to frequent friction or scratches by hard objects. However, scratch-resistant UV coatings based on nano-zirconia are becoming the preferred solution for protecting various surfaces due to their excellent hardness and fast curing properties.
Core technical advantages of scratch-resistant UV coating
UV (ultraviolet) curing technology is widely used in the fields of coatings, inks, and adhesives due to its advantages such as high efficiency and energy saving (curing in seconds), environmental protection, low VOC, and excellent performance. The core of its scratch resistance lies in:
High-hardness nanofillers: such as nano zirconium oxide (ZrO₂), whose Mohs hardness is as high as 8.5 or above (close to sapphire), much higher than many common substrates (such as plastics, wood, and ordinary coatings).
Dense cross-linked network: UV resin instantly forms a highly cross-linked three-dimensional network structure under the action of photoinitiators, providing strong mechanical support.
Nano-enhancement effect: Uniformly dispersed nano zirconium oxide particles are embedded in the polymer network, significantly improving the rigidity and scratch resistance of the coating.
Shenzhen U-Sunny's N-1715 nano zirconium oxide powder, with its ultra-fine particle size, excellent dispersibility and high purity, has become an ideal choice for improving the scratch resistance of UV coatings.
N-1715 nano-zirconia: giving the coating a super strong "armor"
Integrating N-1715 nano-zirconia into the UV coating system brings significant improvements:
Hardness leap: significantly improves the surface hardness of the coating (pencil hardness can reach 3H-6H or even higher), effectively resisting scratches caused by daily friction, keys, gravel, etc.
Wear-resistant and long-lasting: Reduce surface wear, keep it bright and new for a long time, and extend the product life and aesthetics.
Transparent and lossless: Nano-scale particle size ensures that the coating maintains excellent transparency and gloss without affecting the appearance of the substrate.
Fast curing and compatibility: Good compatibility with UV resin system, does not affect UV curing speed and process efficiency.
Good stability: Good weather resistance, anti-yellowing, adaptable to a variety of indoor and outdoor environments.
Diverse applications, protecting surfaces everywhere
1. High-performance coatings
Wood paint: protect high-end furniture, wooden floors, cabinet countertops from scratches and wear, and keep them looking new over time.
Plastic paint: used in automotive interiors, electronic product housings (mobile phones, notebooks), home appliance panels, etc., providing high-end texture and strong protection.
Metal coating: protect the surface of metal decorative parts or functional parts, prevent scratches and enhance texture.
2. Functional inks
Packaging printing inks: used in high-end cosmetic boxes, electronic product packaging, luxury labels, etc., to give the surface anti-scratch and wear-resistant properties, improve product grade and protection during transportation.
Anti-counterfeiting wear-resistant inks: used in the field of anti-counterfeiting logos that require high wear resistance.
3. Special adhesives
Optical adhesives (OCA/OCR): In the lamination of protective films and touch screens, the surface scratch-resistant layer is crucial. UV-curable wear-resistant coatings containing N-1715 can effectively protect the components under the screen.
Electronic packaging adhesive: protect the surface of precision electronic components from accidental scratches during assembly or use.
4. Industrial protective coating
Applied to instrument panels, control panels, equipment identification plates, etc. to resist wear caused by frequent operation.
Shenzhen U-Sunny's N-1715 nano-zirconia, with its unparalleled hardness and stability, has become the core engine for creating top-level scratch-resistant UV coatings. It not only solves the "fragile" pain point of the surface, but also creates lasting value for customers by improving the durability and aesthetics of the product.
