Main characteristics of PVB resin
1.Low viscosity 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.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;
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.Low viscosity 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 condition of PVB resin:
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.
