water based preprinted slip proof varnish for paper finishes

water based preprinted slip proof varnish for paper finishes 1.excellent abrasion resistance 2 .high-temperature resistance

Product description:

GB9007A water based preprinted slip proof varnish for paper finishes is suitable for gravure printing machine, flexography printing machine, independent varnishing machine. For high-speed connection packing preprinted varnishing, it is good choice. Such as beer carton, milk carton, fruit carton, tobacco carton etc.Excellent abrasion resistance, high-temperature resistance, water proof , anti-slip, high gloss, drying fast are its  merits. It is smooth when passing through paper board production line. Printed ink do not fade, and scratch resistance and abrasion resistance are good.

Instructions:

1.Stir must be fully before use, maintain internal composition uniformly. After opening, storage should be stamped seal, stop impurity from polluting varnish and effective solvent volatilization in varnish, prevent affecting varnish performance.2. According to coating machine and climate, add appropriate thinner (water) or mix liquid of alcohol with water (2:1) dilute. In order to avoid loss of gloss and keep wearing resistance, depend on season, roller coating varnishing and flexography varnishing can directly use,gravure printing dilute about 10% thinner. During use , when varnish viscosity is too high, appropriate thinner should be added to adjust right viscosity.3.Varnishing amount should depend on paper quality, generally:3-6g/m2 on coating and flexography printing machine, 2-5 g/m2  on gravure printing machine.

 Note:

1.Varnishing amount should take meeting paper size as principle. If dilution is excessive, it will affect gloss and wearing resistance and ; On the contrary, dilution is insufficient, it will result in varnish coating too thick, poor liquidity.2.Drying method can adopt infrared, hot air, or heat pipe to heating and drying.3.Because water based varnish is difficult to wash after dry and hard, so it must keep roller in state of moving and varnish cycle. Before shutdown, roller must be washed, prevent dry.4.This product is water based varnish. When laminating, please try to choose neutral or weak alkali (PH≤11) adhesives. Please strictly control amount of glue, prevent excessive glue penetrate paper from anti sticky.5.Regularly wash varnishing equipment and store varnish tank. Prevent impurity and precipitate in tank dissolve in varnish from affecting varnish quality.

Storage environment: sealed and stored in dark and dry and cool place; store temperature is 5-30°C.Shelf life: six month under normal circumstances
