Name: water-based overprint varnish
Model: H-6042C
Use : in-line water-based overprint varnish ,wet-on-wet printing
Description: H-6042C is a high-gloss water-based environmentally friendly pressure-line varnish (commonly known as polished overprint varnish). With high wear resistance, excellent gloss, good gloss and color retention, fast dry, good printability, the wet-wet and wet-dry printing has good wetting leveling, easy to clean the printing machines characteristics. Can afford to use version, version off smoothly, giving the print quality of the mirror effect. Used for electronic and electrical appliances, pharmaceuticals, packaging and other high-grade alcohol and tobacco packaging. This varnish is used wet-on-wet coating, can also be used wet-on-dry coating.
Appearance: milky white liquid,
Solids content41%,
Viscosity (seconds): 20 ~ 24, (Viscosity Cups 3 , 25℃),
Gloss: 80 ± 5
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 3-7 / 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.
