preparation
Temperature control: The construction temperature of water-based UV varnish should be between 20-25 degrees Celsius to ensure optimal viscosity and flowability.
Equipment preparation: Ensure that the coating equipment is clean and dust-free to avoid impurities affecting the coating effect.
Stir the varnish thoroughly before use to avoid layering.
Construction precautions
Temperature control: During construction, the ambient temperature should be maintained at 20-25 degrees Celsius to avoid rapid curing of the varnish.
Avoid UV exposure: During construction, avoid direct contact between UV varnish and UV rays. Thick curtains should be used to cover windows during indoor construction.
Viscosity adjustment: The viscosity of water-based UV varnish changes with temperature, becoming thinner when heated and thicker when cooled, and needs to be adjusted according to actual conditions.
Coating thickness: The coating thickness should not be less than 1 μ to ensure the polishing effect.
Preventing pinholes and sticking back: The suction pipe in the pumping system should be placed at the bottom of the polished oil drum, and the return pipe should be placed on the surface of the polished oil to avoid the generation of bubbles and pinholes due to impact; After printing, control the temperature of the paper stack to be below 36 degrees Celsius to prevent sticking back.
Storage and safety measures
Storage conditions: Water based UV varnish should be stored in a cool, dry, ventilated place, away from sunlight and heat sources.
Safety measures: Wear protective gloves and masks during construction to avoid direct contact between oil and skin; If accidentally splashed on the skin, immediately wash with soap.
