·Product appearance: Tiny, free-flowing white powder.

·PVB resin meet the following regulations regarding food contact plastic material:

1)    The REGULATION (EC) No 1935/2004 – Article 3.1;

2)    COMMISSION REGULATION (EU) No 10/2011 on plastic materials and articles intended to come into contact with food;

3)    The United States food and drug administration’s 21 CFR § 175.105 adhesive, 21 CFR § 175.300 resin and polymer coating, 21 CFR § 176.170 paper composition and paper board contact with water and high fat food.

·Product’s main characteristics:

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, acetone condensation resin, alkyd resin, maleic resin and other natural polymer;

Suggested quantity added to: 18-30% for SDL-28/SDL-28B; 15-20% for SDL-18/SDL-18B; 10-15% for SDL-08/SDL-08B; 5-15% for SDL-04,05,06/SDL-04B,05B,06B;

3.      Dissolve under normal temperature (25), 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 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.
