Excellent Solvent Resistance Polyvinyl Butyral Resin For Gravure
Printing Ink
PVB resin dissolve under normal temperature (25 ℃ ), the
dissolution time is 30 minutes min.,this characteristic has greatly
increased the ink's solubility.
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;
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:
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.
