Application
PVB resin has a lot of application:
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.
Characteristic
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 fim;
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, amd could be used together with alcohol soluble condensation resin, alkyd resin, maleic resin and other natyral polymer;
3.Dissovle under normal tempearture(25ºC), the dissolution time is 30 minutes or less, this characteristic has greatly increased the ink's solubility.
4.Low viscosity PVB resin has good wettability and pigmnet dispersion;
5.Non-toxic, tasteless, odorless, no aromatic element, no heavy metal, no plasticizer, is the first chocie of resin for environment friendly printing ink.
Store
PVB resin should be stored under a dry and cool(25ºC or less)condition, the product can be stored for at least 12 months if sealed in original packaging.
Preventive measure
During the operation process of dissolving PVB resin, appropriate take safety measure, and prevent electrostaic.
