Description
Water-based UV Resin (High Adhesion) is a polymer material synthesized through specialized processes using water as the primary dispersion medium, exhibiting exceptional crosslinking capability to form highly interlinked structures. Under UV irradiation, the photoinitiators within the resin absorb light energy, triggering rapid cross-linking polymerization reactions among numerous functional groups within the molecules. Compared to conventional water-based UV resins, this process forms a denser, three-dimensional polymer network structure. This unique structure endows the product with superior performance characteristics. Additionally, the use of water as the solvent reduces reliance on organic solvents, lowers VOC emissions, and aligns with environmental principles. It is widely applied in fields demanding high material performance.

Product Features:
Ultra-High Crosslink Density: Its unique molecular structure and reaction mechanism form a highly crosslinked three-dimensional network after UV curing, achieving significantly higher crosslink density compared to conventional water-based UV resins. This structure markedly enhances material properties such as hardness, abrasion resistance, and chemical corrosion resistance.
Exceptional Physical Properties: The cured coating exhibits extreme hardness, effectively resisting high-intensity scratches and abrasion. It remains intact under external impact without cracking or peeling. Excellent flexibility ensures the coating maintains integrity during substrate deformation, adapting to diverse complex applications.
Superior Chemical Stability: The highly cross-linked structure provides outstanding resistance to chemical corrosion, enduring prolonged exposure to acids, alkalis, salt solutions, and various organic solvents. This makes it highly valuable in industries demanding high chemical stability, such as chemical processing and electronics.
Outstanding Weather Resistance: Even under prolonged exposure to harsh conditions like UV radiation, high temperatures, and humidity, the coating resists aging, chalking, or fading, maintaining stable performance and appearance. This makes it suitable for products requiring long-term outdoor use.
Rapid Curing: Under UV light exposure, the coating cures within an extremely short timeframe, significantly boosting production efficiency. It is well-suited for large-scale continuous and automated production, reducing manufacturing costs.
Environmentally Friendly: Utilizing water as the dispersion medium substantially reduces organic solvent usage and lowers VOC emissions. This meets environmental regulations and supports green production and sustainable development.

VI. Application Method:
Mixing: Based on specific application requirements, blend the water-based UV resin (highly cross-linked) with suitable water-based photoinitiators, pigments, fillers, and additives (e.g., leveling agents, defoamers, adhesion promoters). First, thoroughly mix the resin with water. Then, slowly add the other components one by one, stirring vigorously until the mixture is uniform and all components are well dispersed. Note the ratios and addition sequence of each component; adjustments may be made as needed to optimize performance.
Application: Multiple application methods are available, including spraying, roller coating, and squeegee coating. Before application, thoroughly clean the substrate to remove oil, dust, impurities, etc., ensuring the surface is dry and smooth. During application, strictly control coating thickness, typically recommended between 8–30μm. Final thickness should be determined based on product requirements and application process to ensure coating uniformity and curing effectiveness.
UV Curing: Immediately after application, place the coated substrate into UV curing equipment for curing. Select an appropriate UV light source (e.g., UV mercury lamp, UV LED lamp) with suitable power and wavelength. Adjust the UV energy (typically 800–1500 mJ/cm²) and curing speed based on coating thickness and resin characteristics to ensure complete curing and achieve optimal performance.
Storage and Transportation:
Storage Conditions: Store the product 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 performance degradation due to heat. Keep packaging sealed during storage to prevent moisture evaporation and contamination from external impurities.
Shelf Life: Under proper storage conditions, the product typically 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 for quality assurance before use.
Transportation Requirements: During transportation, avoid impacts, crushing, and inversion to prevent packaging damage and product leakage. Transport using standard chemical shipping methods. Do not transport with flammable, explosive, or strong oxidizing hazardous chemicals. Implement insulation measures during cold-region transport to prevent product freezing and performance degradation.
VIII. Safety Precautions:
Operational Protection: Operators must wear protective gloves, goggles, masks, and other protective equipment 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: Dispose of product packaging waste according to local environmental regulations; do not discard arbitrarily. 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 specifications can be provided upon customer reques
