Name: water-based varnish
Model: H-5303C
Use :for in-line printing , wet to wet printing , matt ,for paper package .
Description: H-5303C is an environmentally friendly oil dumb fast printing, excellent wear resistance, good leveling characteristics. Fast drying and good printability. Wet ink on good wetting leveling, strong resistance to alcohol, printing machine is easy to clean. Used for frozen packaging, bottled instant noodles, electrical appliances, wine packaging and other high-end printing cigarette packaging. This varnish coating for offset printing blanket, inline coating, glazing, and off-line flexo coating.
Appearance: milky white liquid,
Solid content 40%,
Viscosity (seconds): 18 ~ 20, (Viscosity Cups 3 , 25℃)
Gloss: 6 ~10
Notes:
1, It based on conditions of use plus appropriate diluent (water) or alcohol and water (1-5:1) mixture dilution. In order to achieve gloss and abrasion resistance requirements of the situation according to the paper, roll coated with light plus 5 to about 15% thinner, with inline coating liquid, the use of high viscosity coating process should be adjusted to increase the amount of diluent the appropriate viscosity.
2, Varnish on paper should meet the principle, if excessive dilution will affect gloss, abrasion resistance and leveling; the contrary will result in dilution of inadequate leveling varnish is not good, the drying rate is too slow .
3, depending on fuel quality and gloss paper requirements, are generally on-line coating of :2-5 g / m, offline coating 3-7g / m.
4, drying method: to use infrared drying, hot air or heat pipe heating and drying. Drying equipment operation during the first table shows the temperature not lower than 70 ℃.
5, Take 12 hours after polishing of the varnish in order to achieve optimal performance.
6,It can use water to clean equipment, the dry varnish can used Isopropyl alcohol or alcohol to clean.
7, the product of alkali-soluble varnish, when veneer to the cartons (laminating), try to choose a neutral or weakly alkaline (PH ≤ 10) adhesives, when used starch caustic soda glue (yellow glue) fluid, Please be strictly controlled to avoid excess glue with a glue penetrate varnished surface caused by dissolution of the coating adhesive.
Package:
25KG/50KG/120KG plastic containers, sealed in a cool place, the shelf life is one year.
