UV screen printing matt varnish(UVY-713)

One. Introduction UVY-713 screen printing matt varnish suitable for a variety of paper. There are matt, wear resistance, high adhesion, no bubbles and pinholes, dry fast, non-yellowing characteristics. Two. Specifications 1. Appearance: milky white translucent fluid 2. Specific gravity (25C.): 1.10 ± 0.15g/cm3. 3. Viscosity (30C): 1500 ± 200 4. Non-volatile matter: 99% or more 5. Drying speed (80W/cm 3): ≤ 3 seconds Three Using Methods and Notice 1. Construction process: Mixing evenly, using 120-165 meshes silk screen to print, then ultraviolet rays curing. 2. The printing effect of presswork is relevant with the the applied material, working surroundings, temperature, printing pressure of printing press. For to use the same variety of ink, it’s necessary to ensure the of aforementioned printing conditions being stable for avoiding the inconsistency of presswork effects between before-printing and postprinting. 3. Varnish viscosity determine the quality of printed materials, which vary greatly with temperature changes. The same batch printing substrate, confirmed that the viscosity printability varnished after printing to ensure Varnish viscosity constant. 4. Ensure that all printed materials dry, try to shorten the curing time in order to prevent the occurrence printed yellowing phenomenon. 5. Varnish must be completely according to dry, otherwise there adhesion is poor, impatient friction, stick together and easy to scratch phenomenon. 6. Cleaning mesh plate and drawknife apparatus regularly for avoiding superimposition. 7. This product splashed on the skin. Please quickly wash with soap. 8. This product should avoid light, avoid the heat to be stored. 6-month storage period.
