Water-based UV Resin (General Purpose) F2301Paper coating Used for coating the surface of paperSuperior environmental performance
Water-based UV resins are environmentally friendly polymer materials that utilize water as a dispersion medium and incorporate ultraviolet (UV) curing technology. Under UV light exposure, photoinitiators within the resin absorb light energy, generating free radicals or cations that trigger polymerization and cross-linking reactions in the resin's double bonds. This rapidly forms a solid film with specific properties. Compared to traditional solvent-based resins, water-based UV resins reduce orga

Water-based UV resins are environmentally friendly polymer materials that utilize water as a dispersion medium and incorporate ultraviolet (UV) curing technology. Under UV light exposure, photoinitiators within the resin absorb light energy, generating free radicals or cations that trigger polymerization and cross-linking reactions in the resin's double bonds. This rapidly forms a solid film with specific properties. Compared to traditional solvent-based resins, water-based UV resins reduce organic solvent usage and lower VOC (volatile organic compound) emissions, making them more environmentally compliant. They are currently popular materials in coatings, inks, adhesives, and related fields.

Before application, ensure the substrate surface is clean, dry, and free of contaminants like oil, grease, or dust. During application, control the coating thickness, typically between 5–50μm, based on product requirements and application techniques.
UV Curing: Immediately after application, place the coated substrate under UV curing equipment for curing. Select an appropriate UV light source (e.g., UV mercury lamp, UV LED lamp) and control UV energy and curing speed. Typically, UV energy ranges from 600 to 1200 mJ/cm². Adjust the curing speed based on coating thickness and equipment power to ensure complete curing.
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 degradation. Keep packaging tightly sealed during storage to prevent moisture evaporation and contamination.
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-inspection and be approved before use.
Transportation Requirements: During transportation, avoid collisions, crushing, and inversion to prevent packaging damage. Ship using standard chemical transport methods, avoiding co-transportation with hazardous chemicals such as flammable, explosive, or strong oxidizing agents. When transporting in cold regions, implement insulation measures to prevent product freezing.
VIII. Safety Precautions:
Operational Protection: During use, operators must wear protective gloves, goggles, and masks to avoid direct skin contact and inhalation. If skin contact occurs, immediately rinse with copious amounts of water. If eye contact occurs, immediately rinse with copious amounts of water and seek medical attention.
Fire and Explosion Prevention: Although water-based UV resins use water as a dispersing medium, they may still contain trace amounts of organic solvents. Keep away from fire sources and high temperatures. Smoking or open flame operations are strictly prohibited at the construction site. Ensure adequate ventilation in storage and usage areas to prevent the accumulation of flammable gases.
Waste Disposal: Product packaging waste must be sorted and disposed of according to local environmental regulations. Do not discard carelessly. Unused product and waste liquid from cleaning application tools should be collected centrally and handed over to professional waste disposal agencies for treatment to prevent environmental pollution.
