water resistant high-gloss varnish ( H-5102)
Description: H-5102 is an environmentally friendly water-based varnish, with a high gloss, high wear-resistant, clear and bright, gloss retention, fast drying, excellent printability, and the water frost resistance, resistance to alcohol resistance. It is meet the national and EU environmental standards, through the EU ROHS test, compliance with international environmental requirements. Suitable for food packaging, footwear, electronics, pharmaceutical, packaging and other high-grade alcohol and tobacco packaging.
Appearance: milky white liquid,
Solid content: 37%,
Viscosity (Viscosity Cups 3 , 25℃ seconds): 11 ~ 13,
Gloss: 70 ± 6
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,
