Good Pigment Wetting Polyvinyl Butyral Resin For Printing Ink
Polyvinyl butyral resin has good solubility and compatibility, and has good adhesion to metal, glass, wood, ceramics, fiber products, etc.
Applications of PVB resin:
1)Coating adhesive (increase adhesivity, anticorrosive/shop primer, baked enamel, wash primer, paint and coating, used for various base;
2)Ink adhesive;
3)The whiteboard ink adhesive;
4)Textile printing and non-woven adhesive;
5) Engineering ceramic and other ceramics;
6)Organic pigment wetting agent.
Appearance: Tiny, free flowing white powder

Main characteristics of PVB resin:
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 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.
