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 can dilute about 10% thinner, on line machine can directly use. 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: 2-5kg/m2 on varnishing machine, 3-6G/M2 on line machine.

Note:

1. Varnishing amount should take paper thinkness as principle. If dilution is excessive, it will affect gloss and mirror effect degree of cover; 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 heating and drying.

3. Because water based varnish is difficult to wash after drying, 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.
