Waterproof Uv Printing Ink
Waterproof Uv Printing Ink is a waterproof UV printing ink designed for humid, rainy and outdoor high-humidity environments. It achieves excellent waterproof performance through molecular cross-linking technology. It is suitable for a variety of substrates such as plastic, metal, glass, paper, etc. It is widely used in outdoor advertising, packaging printing, electronic labels and other scenarios to ensure that the graphics and texts are persistent and clear in rain, condensation water, and immersion environments.

Product Introduction
Waterproof UV Printing Ink - High Performance for Outdoor & Wet Environment Applications
🌊 Triple waterproof protection mechanism
Molecular-level dense film layer
Using bifunctional acrylic resin, after UV curing, a cross-linked film layer with a thickness of 5-10μm is formed, with a surface tension as low as 28 dynes/cm, a water drop contact angle of ＞110° (reaching IPX7 waterproof standard), and rainwater naturally rolls off the surface of the substrate without penetration residue.
After immersion in 2m water for 24 hours, the ink layer adhesion retention rate is ≥95% (ASTM D3359 100 grid test 4B level), far exceeding traditional UV ink (adhesion drops by 60% after immersion).
Hydrolysis-resistant formula design
Adding carbamate modifiers to enhance the anti-hydrolysis ability of the ink layer, it can be stably maintained in acidic and alkaline environments of pH 3-11 (such as swimming pool water, seawater), and after 500 hours of hydrolysis resistance test (ASTM D570), the color difference ΔE＜1.5, without cracking or falling off.
Edge sealing reinforcement technology
For areas prone to water seepage, such as hollow fonts and fine lines, the intelligent ink drop distribution algorithm (patented technology) increases the thickness of the edge ink layer by 30%, combined with a low-viscosity wetting agent (surface tension 25 dynes/cm) to ensure the waterproof integrity of complex patterns.
FAQ:
What printing equipment is supported? Is small-batch customized printing feasible?
Compatible with mainstream equipment and support flexible production:
Inkjet printing: Low viscosity formula (15-25 cP) is suitable for high-speed models such as Epson SurePress and HP Indigo, supports variable data printing (such as serial numbers, QR codes), and the cost of small batches (starting from 100 sheets) is 30% lower than that of traditional processes;
Screen printing: High thixotropic models (80-150 cP) are suitable for thick film printing (film thickness 15μm), can achieve embossed waterproof effects, and are suitable for outdoor three-dimensional logos;
Customized support: Provide free proofing services, complete special formula debugging (such as fluorescent colors, metallic colors) within 72 hours, and meet the high-precision requirements of luxury packaging, anti-counterfeiting labels, etc.
