Product Description

Polyvinyl Butyral (PVB) Resin

Characteristic

PVB resins can be divided into different levels according to their molecular weight and degree of acetalization.

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 alkyd resin, maleic resin and

other natural polymer;

3.Dissolve under normal temperature (25 ºC ), 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.
