GB900B water based universal high gloss varnishes is adequate for
offset press on line machine, independent varnishing machine,
flexography printing machine. This product is closing ultrasonic,
high gloss, drying fast, good levelability. Its print have good
suitability, and economic and practical, which is used to
varnishing on all kinds of paper cup or paper bowl of Master Kong,
Uni-president, Aromatic Milk Tea. Not only do it can ensure
decolouration, but also improve beauty aesthetics. It can
automatically seal after ultrasonic heating.
Viscosity 12--18S (4# Cai's 25° C)
Solid contents (40± 3)%
Wearing resistance ≥ 200 times (4 pound / copy paper is
not clearly decolouration)
Gloss 65_75 (depending on paper and varnishing machine)
pH value 8.0-9.0
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.
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
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
