Photocurable Polyurethane Acrylate 7620: The "All-Round Armor" for High-End Coatings
In the demanding arena of industrial coatings, photocurable polyurethane acrylate 7620 stands out as a core material for high-end applications such as UV vacuum metallization, ultra-wear-resistant coatings, and UV inks, thanks to its five key properties: high film hardness, excellent toughness, superior wear resistance, anti-yellowing capability, and outstanding adhesion. It equips products with an "invisible shield" that combines aesthetics and functionality.
High Film Hardness
Post-curing, the coating achieves a surface hardness of 4H or higher, rivaling sapphire glass, effectively resisting daily scratches. This makes it the preferred choice for smartphone mirror coatings and vacuum-metallized luxury metal logos, delivering a premium "touch-resistant" finish.
Excellent Toughness
Despite its extreme hardness, the flexible molecular chain design enables the coating to withstand 180° bending without cracking. This breakthrough in "hard yet flexible" performance makes it ideal for dynamic applications like foldable smartphone hinge coatings and curved automotive interior surfaces.
Superior Wear Resistance
Leveraging nano-crosslinking technology, the coating endures over 10,000 wear cycles (Taber abrasion test, CS-10 wheel, 1kg load). It is widely used in high-frequency scenarios such as UV topcoats for premium hardwood flooring and smartwatch dials, combating long-term abrasion.
Anti-Yellowing
With dual protection against UV and oxidation, the coating maintains a color difference ΔE <1 even after 500 hours of outdoor exposure. This ensures lasting clarity for white appliances and transparent packaging coatings, eliminating yellowing concerns over decades.
Exceptional Adhesion
Achieving a 5B rating per ASTM D3359 on metals, glass, and engineering plastics (e.g., PC, ABS), the coating bonds tightly to substrates without primers. This solves delamination challenges in vacuum-metallized coatings on complex geometries.
From shimmering vacuum-metallized jewelry to tech-driven wear-resistant electronic screens, polyurethane acrylate redefines high-end coating standards with its "hardness, toughness, stability, and purity," seamlessly unifying industrial aesthetics with enduring practicality.
