Description
Water-based UV Resin (Silver Powder Specialty) is a specialized polymer material developed for silver powder pigments, utilizing water as its dispersion medium. Through unique molecular structure design and process optimization, it achieves excellent compatibility with silver powder. Upon UV exposure, the photoinitiator absorbs light energy to trigger a polymerization cross-linking reaction, stably encapsulating and fixing the silver powder. This forms a coating with distinctive metallic texture and superior performance. This resin reduces the use of organic solvents and lowers VOC emissions, meeting environmental requirements. It is widely used in coatings, inks, and other applications requiring the metallic effect of silver powder.

V. Product Performance:
Optical Properties: Leveraging exceptional silver powder orientation and dispersion capabilities, the cured coating exhibits extremely high gloss and a distinctive metallic shimmer effect. When light strikes the coating surface, the silver powder efficiently reflects light, presenting a brilliant metallic appearance. The coating also maintains excellent light retention, ensuring the metallic luster remains vibrant and does not fade over extended use.
Physical and Mechanical Properties: The coating exhibits good hardness and abrasion resistance, withstanding daily scratches and wear to protect the silver particles and maintain the metallic effect. It also possesses flexibility, preventing cracking or peeling when the substrate undergoes minor deformation, ensuring coating integrity and aesthetics.
Chemical Properties: The coating exhibits tolerance to common acids, alkalis, salt solutions, and organic solvents. When exposed to mild chemical erosion, it resists discoloration and peeling, effectively protecting the silver powder and substrate. This makes it suitable for applications requiring chemical stability.
Weather Resistance: Under natural environmental factors like UV radiation, high temperatures, and humidity, the coating resists aging, chalking, and yellowing. It maintains its metallic appearance and performance over extended periods, making it suitable for products used outdoors or indoors long-term.
Usage Instructions:
Mixing: First, pour the water-based UV resin (specifically for silver powder) into the mixing container. Add an appropriate amount of deionized water to dilute it to the desired viscosity. Then slowly add the silver powder while stirring continuously. Maintain a low stirring speed (approximately 300–500 rpm) to prevent high-speed agitation from damaging the surface structure of the silver powder. Add appropriate amounts of water-based photoinitiators, leveling agents, defoamers, and other additives. Continue stirring thoroughly for approximately 30–60 minutes to ensure complete dispersion and mixing of all components. After preparation, let the mixture rest for 15–30 minutes to eliminate air bubbles generated during stirring.
Application Methods:
Spray Application: Use air spray or high-pressure airless spray equipment. Adjust spray pressure (typically 0.3–0.5 MPa for air spray, 10–20 MPa for high-pressure airless spray) and spray distance (approximately 15–25 cm) to ensure uniform coating coverage, preventing sagging or uneven application.
Brushing: Select an appropriate brush and apply evenly in a single direction. Avoid repeated back-and-forth brushing to prevent disrupting the silver flake orientation and compromising the metallic effect.
Roller Application: Use roller application equipment, controlling roller speed and pressure to ensure uniform coating thickness. Avoid roller bouncing or pausing during application to prevent roller marks.
UV Curing: Immediately after application, place the coated substrate into UV curing equipment. Select an appropriate UV light source (e.g., UV mercury lamp, UV LED lamp) based on coating thickness and resin properties. Set UV energy to 800–1200 mJ/cm² and control curing speed at 3–8 meters per minute to ensure complete curing and achieve optimal metallic effect and performance.
VII. Storage and Transportation:
Storage Conditions: Store in a cool, dry, well-ventilated warehouse, avoiding direct sunlight and high temperatures. Maintain storage temperatures between 5°C and 35°C to prevent freeze-thaw cycles or silver powder agglomeration and resin degradation due to excessive heat. Keep packaging tightly sealed during storage to prevent moisture evaporation and contamination from external impurities.
Shelf Life: Under proper storage conditions, the product has a shelf life of 6 to 12 months (refer to the product label for specific details). Products exceeding the shelf life must undergo re-testing to confirm that indicators such as silver powder dispersion and coating performance meet standards before use.
Transportation Requirements: During transportation, avoid collisions, crushing, and inversion to prevent packaging damage and product leakage. Transport using standard chemical shipping methods. Do not co-load with flammable, explosive, or strong oxidizing hazardous chemicals. In cold regions, implement insulation measures to prevent freezing, which may impair silver powder performance and resin stability.
VIII. Safety Precautions:
Operational Protection: Operators must wear protective gloves, goggles, masks, and other safety gear during use to avoid skin contact and inhalation. If skin contact occurs, immediately rinse with copious amounts of water. If eye contact occurs, flush thoroughly with water and seek medical attention promptly.
Fire and Explosion Prevention: Although water is the primary solvent, the product may contain trace organic solvents. Keep away from heat sources and open flames during use and storage. Smoking and open-flame operations are strictly prohibited. Maintain adequate ventilation to prevent hazardous buildup of combustible vapors.
Waste Disposal: Discard product packaging waste according to local environmental regulations; do not dispose of it indiscriminately. Unused product and waste liquid from cleaning application tools must be collected centrally and handed over to professional waste disposal agencies for safe treatment to prevent environmental pollution.
IX. Packaging Specifications:
Packaged in 50kg plastic drums. Alternative packaging sizes can be provided upon customer request.
