Product’s main characteristics:
1.Low viscosity PVB resin as the foundation of the printing ink
shows a low solvent resistance, good liquidity, good waterproof,
which could be independently used as the basic resin, and could be
used together with alcohol soluble nitrocellulose, alkyd resin,
maleic resin and other natural polymer;
2.Suggested quantity added to: 18-30% for DR-40; 15-20% for DR-30;
10-15% for DR-20; 5-15% for DR-16/DR-17/DR-18;
3.Dissolve under normal temperature (25 ℃ ), the dissolution time
is 30 minutes min., this characteristic has greatly increased the
ink’s solubility;
4.Low viscosity PVB resin has good wettability and pigment
dispersion;
5. Non-toxic, tasteless, odorless, no aromatic element, no heavy
metal, no plasticizer, is the first choice of resin for environment
friendly printing ink.
Storage:
Under a dry and cool (25 ℃ or less) condition, the product can be
stored for at least 12 months if sealed in original packaging.
Preventive measures: during the operation process of
dissolving,appropriate take safety measures, and prevent
electrostatic.
