Characteristics:
1.PVB resin that is suitable for flexo and gravure printing, has
good adhesion to polyolefins, metal, cellulose acetate, polyester,
cellophane paper, polyamide and polystyrene film;
2. 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, acetone condensation resin,
alkyd resin, maleic resin and other natural polymer;
3.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;
4.Dissolve under normal temperature (25 ℃ ), the dissolution time
is 30 minutes min., this characteristic has greatly increased the
ink’s solubility;
5.PVB resin has good wettability and pigment dispersion;
6.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 condition, the product can be stored for at
least 12 months if sealed in original packaging.
